Hi,
I have the 2810, just set it up this week. Yesterday we had RAIN! When I got up this morning the 24hr Rain amount still said .34 which is what it was yesterday. It didn't reset to zero. The manual says it resets at midnight. So I thought maybe I had the am and pm mixed up. I went into set and checked the time and something odd happened. The date started displaying the DAY first instead of the MONTH like 21.11.09. I looked in the manual and the pictures of the display show mmddyy but the text does say date-month-year. Couldn't find how to change it. Then after awhile (or something I did?) it changed back to mmddyy.
Any ideas why or what I did to change the date display? And why the rain didn't reset? I'll watch it close to see if and when it does reset.
-
My 2315 has the date 211109 (ddmmyy) all the time (I think that's a European thing). I rarely look at the console because it is wired into the computer, so the date doesn't matter too much to me. Also, I have the console clock set to a 24-hour clock so that I don't get the am/pm mixed up.
-
It is valid if the 24Hr field is not zero, depending on when the rain happened the day before. It is a sliding 24 hr window. This is not to be confused with the Rainfall since midnight, which resets at 12am.
-
If you set you clock format to 24hr it will chang the date format to d/m/y
on the 12hr format it will be m/d/y
-
I'm still confused....on page 28 of my 2810 owner's manual, it clearly states that the "Last 24 hours of rainfall reset every day at 12:00am (Midnight).
In the Heavy weather manual, page 26, says the number is for the last 24 hours. Supposedly I can reset in the software, but it never does reset the amount,
only the max resets and the reading for 24 hours stays.
Also, has anyone tested the accuracy of the 2810 rain collector. Mine is mounted level about 5 feet above level ground in the middle of the yard.
It reads 2.05 inches while my 8" Novalynx collector has measured .90 inches on my Maximum Rainwatch, which is for the last 12 years, been
close to what the airport reports. I will get an old fashioned rain gauge and do some testing I guess....the whole rain system on this thing has me
quite puzzled.
-
A rainfall total that resets at midnight is the daily rain total. The 24hr total is supposed to be a sliding 24 hour window. Some units support one or the other, some support both.
Given that other La Crosse units support 24Hr, and not daily, I am guessing you have a 24 hour sliding window.
-
My window is definitely a sliding window with respect to the 24 hour rainfall. The owner's manual just confused me as it states it resets at midnight.
-
If that is the only mistake, someone did a good job with translation from Chinese.
Most software (other than La Crosse) also can report the daily rain total (since midnight).

Bump...

I do have the calibration information on the Novalynx collector. Now I am trying to find some relationship between the diameter of the collector(s). The Novalynx is an 8" diameter collector. So if I dump 250mL of water through it, the same 250mL of water through a smaller diameter collector, as with the 2810 will probably read differently...
Any ideas??
-
I read in your previous post that your Novalynx measured .90 inches of rain. Couldn't you pour 1" in it (keeping track on how much you pour) then again the same amount into the 2810?
-
I could indeed do that, but as I am wondering:
If I pour 250mL into the Novalynx and it measures 0.XX inches or XX tips of the bucket....
I don't believe that the same volume, 250mL of water into the LaCrosse will yield the same number of tips as the "buckets"
are not the same size. I haven't measured the diameter of the LaCrosse rain collector but it is definitely
less than 8 inches, which is what the Novalynx diameter is.
It seems that the tipping bucket size would have to be calibrated to the diameter of the collector itself.
Never really put this much thought into the tipping bucket mechanism/sizing, but it is interesting!
-
The catch area, bucket design (tip distance, size,etc.) will be different for the different rain gages. They are constructed so the mechanisms are designed to match the catch area. 250mm of water poured through both gages will more than likely give different bucket tip counts but the calculated displayed result should be 250mm of water for both.
-
I know from the calibration documentation for the Novalynx, it takes 8.24mL of water to tip the bucket and yield a 0.01" incremental reading on my display.
The question is..."How many mL of water will cause the LaCrosse bucket to tip, which will express an inch of rain being collected via it's catch area?"
The buckets on the Novalynx are MUCH larger than those on the LaCrosse, so the same 8.24mL into the LaCrosse will yield quite
a few more bucket tips.
If I measure the catch area of the LaCrosse and relate that to the Novalynx as a percentage, then decrease the 8.24ml by the same
percentage.....
Might be a starting point....I don't even know if the LaCrosse gauge is user adjustable as the Novalynx is.
-
It's not that hard...
Calculate the area of the 2810 rain collector in inches.
Multiply by 1 to get the cubic inch volume of 1" of rain it collects. (I know, a somewhat meaningless step.)
Convert that to whatever units of volume you can accurately measure. Google can do this. Say it's 6 cubic inches, and you want is in milliliters (ml).
In the Google search box, enter:
6 cubic inches in ml
and it will return
6 (cubic inches) = 98.322384 ml
Slowly trickle that volume of water through the collector and see how close you get to 1.00" of rain.
"Slowly" means take as long as you can, at least 20 minutes (a 3"/hour rain rate) to an hour (1"/hour rate), to do it.
-
From previous post:
"Multiply by 1 to get the cubic inch volume of 1" of rain it collects. (I know, a somewhat meaningless step.)"
My Novalynx has an 8" diameter collection diameter...this is a collection area of 50.26 square inches.
If I multiply this by 1 to get the cubic inch volumie of 1" collected rain I get 50.26 cubic inches,
which is 823.61 mL. Divide this by 100 to get 8.236mL per one inch of rain, which is essentially what the calibration manual says (8.24mL = 0.01" of rainfall).
Thanks SLOweather....I'll see what I can come up with when I get home. I don't know right off what the diameter of the
2810 collector is but will measure this evening. I will post my findings later on with the method used and see if others
can corroborate.
Best regards,
Gman19

"Divide this by 100 to get 8.236mL per one inch of rain..."
Should read "Divide this by 100 to get 8.236mL per 0.01 inch of rain"
I rarely catch myself....lucky Friday I guess!
-
gman19, Are you having any luck with the formula's and the rain guage tweaking? I finally have my new 2810 station installed and going through the temp/humidty/dew point calibration and check out. I did run a quick check on the rain guage when I pulled it out of the box by pouring a 1/2" equivalent of rainfall through it and mine read high as well. I have ideas on how to adjust that but before I make any modifications to it I'd like to see it perform in an actual rain storm first. That will be a more accurate test for it I believe. So far the temp/humidty testing is giving excellent results! It's a learning experience as I go too. I'm lucky to have several sources to compare with while making my adjustments. There's an international airport a half a mile west of me and a Thai Meteoroligical Department station right next to it that provides METAR reports every 30 minutes (usually). Lots of fun. Keep in contact and we might be able to help each other out.
Cheers!

I had the feeling that my 2810 is posting double of the actual rainfall. When I called La Crosse they told me that the test for the rain gauge is:
1. pour water into the gauge and count the number of tips until you reach 10, this should equal 0.19"
2. Wait 15 minutes
Do step 1 and 2 three times
I asked why you not just manually tip the paddles 10 times, he stated that the preferred method is by pouring water into the gauge. I have not done this water test yet.
We finally got some rain yesterday and last night:
2810 rain gauge 0.63"
Walleyworld rain gauge 0.31"
Coffee can, I'm guessing around 1/4"
We are expected to get another storm in that could be around 1". With that much rain my coffee can should be measurable.
-

I would highly recommend joining CoCoRaHS (http://www.cocorahs.org/)!
It is a precipitation measuring project all over the country and we are always looking for volunteers. I'm sure other CoCo guys and gals here will back me up on this. You need to get a good manual gauge to calibrate your 2810 anyway. The CoCoRaHS gauge is an excellent gauge IMO. Check it out here (http://www.weatheryourway.com/cocorahs/rgcoco.htm).
Good luck!

???? Should have asked him/her "how do I know if I poured a gallon or 2 ounces through to get the 10 bucket tips?". It sounds like that test is good for checking the electric/mechanical and software portion but does nothing for measuring quantity.

I sure wish CoCoRaHS would expand their coverage to outside U.S. boundries and go worldwide. It rains outside the U.S. too! There are people who travel that could benefit from this coverage. I for one would jump at the chance to join up and contribute. Can't understand this. I contacted a CoCo rep. a while back and asked this. I was told "thank you for your interest but at this time ....blah blah blah" and so on. :roll:
-
Still wating to hear from them. inquired into it when thet first started hr. Seems like they where only interested in the Matsu valley area. Think alaska polictics where in play more then research.

Looks like I'm having the same issues with my rain gauge. I'm getting constantly twice the rain measure that every other station around me is getting.

It looks like the LaCrosse tech only covered part of the cal. procedure. He/she did not specify how much (quantity of) water is required to tip the buckets 10 times.
I've gave mine a quick look out of the box and it appeared to be set to read high also (around 1.5" for 1" measured). Since the WS-2810 gauge measures 4.5 inch diameter this equates to 15.906375 sq. in. area. 15.906 cu. in.= 260.6588 milliliter = 8.813922 oz. for 1 inch of rainfall. After making some adjustments and pouring water through the gauge many times it now reads close to 260ml gives for 50 tips and reads ~ 1.00" on the console. Need a real rain storm to confirm now before tweeking more if need be.
-
Did you make modifications to the rain collector? or just manipulate the data that is being uploaded to the web? I have an idea for modifying the sensor... maybe some sort of cover for half of the collector?, I'd be interested to see what you've come up with.
-
Yes, making internal adjustments to the gauge itself. I personally don't like "bandaid" fixes where you cover up the issue with software adjustments if the discrepancy can be corrected. The bucket stops are just plastic walls and I'm playing with removing these and replacing them with machine threaded screws for adjustments (like LaCrosse should have done in the first place. Cutting costs I suppose).
-
interesting. does the rain gauge measure rotation on the shaft as the buckets are emptied out or does it simply count buckets?
if it measures rotation than you're on to something. if it's measuring buckets filled with X amount of fluid I dont see how this would work.
In any even I'm interested to see pictures and a write-up on what you have done. It's the rainy season here.
-
The bucket tips are measured using a small magnet on the bucket assembly itself. The magnet passes a reed switch mounted close by. Each reed switch closure is counted as a bucket tip. Raising the stop adjustments speeds up the tip counts and lower these stops, slows the counts. It's a very fine adjustment process that's why the machine threaded screws.
-
The first pic is what it looks like originally. 2nd pic shows the two bucket stop walls cut out and replaced with stainless machine threaded screws. 3rd pic shows view from the bottom and 4th pic reassembled (notice in this pic how much further the bucket needed to drop from the factory setting on the wall). I chose the screws inserted from the bottom so adjustments could be made without removing the bucket assembly.
Pouring 260ml of water (=1" rain) through countless times gave readings in the range of 40 bucket tips with screws almost all the way out up to 65 tips with them inserted fully.
I left the adjustments at 25 tips for just over 130ml (1/2" rain) of water for now to see how it does against the manual gauge with the next rain shower. Even left like this it's much closer than it was out of the box.

This morning I had nothing planned and I'm very anxious to see how the gauge performs after the mods so I tried out my rain gauge cal/checker (http://www.wxforum.net/index.php?topic=6764.0) to see how close everything was. The rain gauge read 0.60" for the calculated 130.3 ml of water poured through on the first check. I took the gauge down and adjusted the screws out 1 turn and ran more water through. Now it reads 0.50" or close for each time and, as I said previously, I just have to wait for the rains to return for the real test.
-
Last night we had our first thunderstorm since the gauge modifications were made. The results are now tracking the manual gauge and the 2310's readings very closely. Last night's rain shows about .17" on the manual and 2810's gauges (placed next to each other) and .15" up on the 2310's gauge (roof level). We had high winds at that time so I'm not confident with comparing to the 2310 but at least feel the 2810 gauge correction worked.
-
Good Job, wish I had all the free time you have. =D>
-
nice work Dan. If my 2810 makes it out of 'probation' I'll go back and re-read your notes.

Although it may not be as accurate as Dan's mod......I modified the rain gauge by reducing the capture area. Today we got some snow and my Rainwise recorded.01″…then….02″ The 2810 showed .02″ Not sure if it went from .01″ but I did get the same result. Monday we’re suppose to get some real rain so I’ll let you know how it measures up.
Here’s a link to some pictures I took:
http://www.flickr.com/photos/vajim/
The pic of the 2810 is the original (back to Costco). The 2nd one is in the same place.
Parts list:
1 lid to plastic butter container (4.5″ diameter)
1 lid to Noxema shave creame

That's some original thinking! Good job! =D>
-
UPDATE on the rain gauge....today we got our first measurable rain since I did the mod. Here's what my stations reported:
Lacrosse 2810: .38
Rainwise: .26
Davis Vantage Vue: .24
Although the Lacrosse is still not there, it's getting close. Once we dry out I'm going to remove the cap from the Lacrosse and check the seal around the cup.
-
Good job there VaJim. Zeroing in on it! The way I figure it, you should have a 3.182" opening if the original error is exactly doubling (2x) the readings.

Great job Dan congratulation,I like the clever solution with screw for you going depth ,the tiping bucket,and it make little more time to go again up,for show the correct rainfall and you resolve the problem ;)
I hope you put a nuts -safety at two screws,for it not go up-down easy,and you loose the correct tuning for the tipping bucket.
I will make other modification for this problem ,i will make smaller the surface at collector.
Any way i like your solution :-)
Now i saw this topic ,if i understand well 2810 rain gauge have a small problem,it show more mm from normal analogue rain gauge (cocorahs) ?
Because i do not understand about inch but i know from mm measurements .Do you can tell me how mm it show more for the normal ?
Thank you
Keep up the good work :grin:
-
Hi Dimitris and thanks.
The WS-2810 appears to be made with the rain gauge reading near 2 times the actual rainfall. Inches or mm measured is doubled when compared to an analogue gauge. I personally believe that the system was developed with the firmware in the console set to read twice what this gauge resolution is set for. What I did is adjust the buckets to tip half as often as factory setting to more closely match the firmware. The adjustment is the same when converting in inches or mm when you just cut in half. VaJim has done this using another approach, cutting the collector opening area down. :-)
-
Ok Dan i understand the problem,no have same corelation with console from firmware problem,this is a big defferents double mm or inch :???:
Because i saw the rain gauge 2800-2810 http://www.nouveauxobjets.com/2800.php (http://www.nouveauxobjets.com/2800.php) it the same with 3650 model http://www.nouveauxobjets.com/3650.php (http://www.nouveauxobjets.com/3650.php) do you know if the same problems had and they work 3650 operator ?
-
That's interesting Dimitris. I had the impression that possibly the gauge for the 2810 was "borrowed" from another system and just some designer confusion between the .01" / .02" (.25mm/.5mm) hardware / software setup. Seen that happen before (didn't NASA recently have a similar thing happen with a rover enroute to Mars?). Your observation with the 3650 gauge makes this a very real possibility. :-)
-
...also it's worth noting that if you look at the 2810 manual, it says the rain gauge measures 5.18" diameter, yet when you actually measure it, it's more like 4.5" diameter. What's that all about? I tend to agree with Dan in that somewhere, some how they pushed/packaged the wrong display to the wrong gauge. :roll:
-
Yes, they measure the mount/base dimensions not the actual collection area at the top. It is indeed, like you say, 4.5". If you make adjustments using the mount dimensions you'll get all screwed up. :???: ;)
-
..good catch Dan!...their measurement of the base/mount makes sense in needing to know the space required for mounting. I used the top measurement for my intake mod. :-)

-
Dan: Another question on your 2810 rain gauge mod, does yours now get the display to actually show increments of .01"? Does it move from .01, .02, .03, etc?
-
Mine has always incremented in steps of .02". Just too fast/often in it's original configuration. Now if we could get some rain here to see it in action. :roll:

Having the same problem as everyone else with the rain gauge double the actual amount, I've used this approach. I used a flex 4" to 3" coupling, with a 2-1/2" PVC coupling inserted into the flex coupling ( these are nice water tight joints). The PVC coupling was beveled on the inside and outside edges to give it a sharp diameter of 3.130". We have had some rain and the results are :
Manual Gauge 1.37"
2810 1.35"
During this storm there was lots of wind and heavy downpours at times, so I do not plan on making any adjustments until further data is collected.
-
Nice job Lou =D>....nice pic. Now if I can just see your shopping list..(Home Depot/Lowes?)
-
Good job Lou! Your 3.130" adjustment is very close to the 3.182" calculated. Pretty handy to have ready made material available.
-
DanS I really like your mod with the screws to adjust the bucket tips. Could you share just what size screws those are and are the black collars threaded? I picked up some stainless screws and some expansion nuts but I think my items are to big. I dont think the expansion nuts will hold the screws tight enough once the adjustment is made. Any help would be great! :grin:

Hi Duck Fan. I just used a set of 8/32 stainless screws and 2 nuts on each. You could use smaller like 6/32's with no problem. I just had these available. Those black "collar" looking items in the photo are just nuts placed on each side of the gauge floor. Just snug them up until you're all tweaked in with your adjustments then tighten in place. I don't believe the gauge floor is thick enough or has enough reinforcement to support expansion nuts but the way I did mine with a nut on each side seems to do the trick for this application. Cheers.
Dan
-
Thanks Dan, Easy enough. I should have put my glasses on to get a closer look #-o I also built the baby bottle tool for checking so I am set to fine tune this rain gauge. Thanks again for your help. =D>
-
No problem and hope you get it all setup with no problems. That baby bottle tool makes adjusting and measuring a lot easier too. When you add the measured water to the bottle and flip it over in the gauge funnel, turn it over so that the little straw gets air in the bottom of it as you flip it to clear out the water inside. It flows smoothly this way. :grin:
-
Ok Wow, I think I may have the rain gauge pretty darn close. \:D/. I have ran 130ml of water through it and getting .52 on the reading. :grin: I will set this up now on its perch and wait for rain. Hear in Oregon, we do not have to wait long for rain. ;) Dan i seemed to have managed this without using the screws. I took my dremel and removed the plastic so the bucket could tip down farther and noticed it was stopping itself on the wide part of the bucket on the battery tower. At this point i was getting a .66 reading. I shaved a little off the bucket to let it fall a little bit further and now getting the .52 reading. Make sense? Clear as mud? :roll: I will watch this work in real conditions and let you know.... :grin:
Nick
-
Understand about shaving the buckets to clear the battery tower. You would have to have both sides shaved the same amount to stop them at the same point in their downward travel and also for the balance of the bucket assembly. Hope it works o.k. and good luck with the upcoming rain check-out. :-)
-
Hello,
sorry for my bad english.
Now, in france you receive from LaCrosse, new Th/hygro for correct problem of rain. I have tested this new one this week. With this, one enr data on two is really saved (it's not good for precison).
Have you remark that wind gust diplay on station is not saved in next data ??!!. for me, a wind gust 71 KMH at 9h42 is save at 9h45 59,4 KMH. (one enr every 5 mn).
-
OK, We are finally getting some rain and my rain gauge SEEMS to be dead on :grin: I will continue to monitor this. \:D/ Thanks Dan for your help on this. Was a little worried when you said even on both sides of the bucket for balance. I did have that in my mind when i shaved off the sides of the bucket where it was hitting the battery tower. Same principal when balancing a lawn mower blade. Set the blade on a balancer and if leaning on one side, shave off some metal on that side. :-)
-
Good to hear that your tweak got the problem resolved Duck Fan! Still waiting for some showers here to confirm mine. Way too dry around these parts. :-|
-
Hello for all,
Sorry my english is same as spanish cow.
Now, after replacement of Th/Hygro probe (not a solution), we start a procedure (I don't know the good term in english) on LaCrosse Tecnologie for latent defect.
This procedure is on Double rain, not good saved rain gust datas.
On this procedure we add the problem of long tile of re-synchro betheen Pc and station.
If you want you can join our group, send me a personal message.

..If I understand you correctly, it sounds like Lacrosse replaced the thermo sensor in an effort to fix the double rain fall amount...??
-
This procedure is on Double rain, not good saved rain gust datas.
That sounds like a problem others have been having with the 2810. I don't have one, but it sounds like a job for Super Dan (that's what I think the S is for!)

...true..Dan has already tackled the problem with a internal mod. I was wondering what if any did Lacrosse say about the rain gauge problem. :lol:

I haven't heard any news with regard to this. I feel they should offer a firmware upgrade that owners could download to correct the problem if possible (for those who don't do the physical mods we've done). I see LaCrosse has upgraded the HW Pro software a version though. I downloaded that but haven't seen much improvement over the last version.

I'm not sure you can load a firmware update to the 2810..??? :sad:

I'm wondering about that as well. The console/display has 2-way comms capability with the PC so being able to send to it is possible. I guess it's just a matter of what kind of chip set is used.

Good night
Are you sure that WS 2800 have a com port ?

The 2810 (usa) has a USB device that plugs into the PC. It receives data from the display (?) and uses it in the HeavyWeather software.

Hello,
I am a french user of WS 2800.
prepahs I have not good understand. But one of person on this forum say 2 comm ports. I am not shure it's a reality. It's important. if its'good, prehaps it's possible to make a release of firmware. If not, a release of firmware need a change of station.
-
pschnell,
As VaJim mentioned, the 2810 uses a USB stick on the PC for the communications link between the two. I was referring to this communications link being a 2-way link. The communications are in both directions because when you make changes in the HeavyWeather program the changes are uploaded to the console. As I was saying above in reply 67, I believe it may be possible for a firmware upgrade because of this 2-way comms capability. Does this clear things up? Sorry for any confusion.

Hello all and specily to Dans,
Now I anderstand. The Usb connexion is two ways connexions.
I have contacted LCT, and they say me, that now it's not possible to do an upgrate of firmware.
It's for me the last post. since tree days, I have send my station to LCT. This that it has agreed to reimburse me. So no station since Friday.
I regret that this company has not make the effort to advance the problems of this new station.
Now, I search for a new station.
-
This doesn't sound good. But it does sound like Lacrosse! :-x
-
Thank you for the update pschnell. It's too bad that they are letting it go because it is a nice station when it's corrected and running like it was intended to (especially for the price).
At least I'm happy to hear they refunded your money and hope your next station gives no problems.
Cheers!
Dan

Well I called Lacrosse this afternoon. I explained to the rep that I had called back in Feb about the rain gauge problem. She told me to send in the the thermo sensor and said that they would 'probably' replace it. I took down the mailing and info and was ready to send it off tomorrow. I figured since she was talking replacement and not investigate or repair, they may have a real solution, besides it's not like I would be without a station. After returning from the back yard where I retrieved the thermo sensor, I then happened to check my email and found a note from Lacrosse. At first I thought it was the customary follow up email. This note said to NOT send in the thermo sensor, but they would go ahead and send me a replacement. This would correct the rain fall problem. The note went on to say that the replacement would not be available until September. :sad:
I've learned to be patient with this station. More to follow.
-
Thanks for that update. Good to know that they're doing something about it even though it going to be a little while. It will be interesting to hear from you with the sensor change information when it does arrive this fall.

I just thought I would add that I reported this same problem originally in January and La Crosse blew me off multiple times. As the end of my 1-year warranty is coming up I complained again, and they had me go through the pour water in for 10-tips thing and send the results. They then replied and said to pack up the whole unit, display, sensors, and all and send it in to them. Once they get it they said they would send a WS-2812U-IT system in return, but they don't have any right now so it could be a few months. (They did say the 1-year warranty would start over.)
I saw that Costco had the WS-2812U-IT for ~$80 a few days ago so I might just go buy one of those and then have a complete spare system.
-
After all the hassle of the waiting, shipping/packaging, etc. I would tend to agree with you and go with your Costco idea. Worse thing that could happen would be the new 2812 still has the same problem but since you said LaCrosse would send you one as a replacement it sounds like it's been corrected. And as you also mentioned, your existing 2810 parts could be used as spares (except the thermo/hygro sensor) for you new 2812. Extra display, rain, and wind sensors. Good luck with your decision.
-
I wonder if the reason they offered to replace the whole unit is that I mentioned that the manual states a 0.01" accuracy and maybe the thermo replacement divides the rain data in half as a workaround that is cheaper than replacing the display. I guess we will find out when I get the new one hooked up.
I've decided to buy the 2812 and send the 2810 to La Crosse for replacement. (I couldn't stand to be without it for 2 months.)
This will be my third La Crosse station from Costco. The first one was a 2308, but the wireless stopped working. The anemometer was never very good either, the turbine style that would freeze up at the drop of a hat.
Other than the double rain reading I have been happy with the 2810. (The only other problem I had was that the anemometer would fail to report sometimes but I had a metal roof blocking the wireless signal.)
Hopefully the weather will co-operate this weekend for me to go up on the roof.

And as you also mentioned, your existing 2810 parts could be used as spares (except the thermo/hygro sensor) for you new 2812. Extra display, rain, and wind sensors.
Looks like that isn't the case. Here are some notes from their current HeavyWeather software for the 2812:
- This version of the Heavy Weather Software only works with the WS-2812 model weather centers.
- The 2812 display and sensor firmware were revised to calculate rain totals a bit
differently. Therefore, the software was adjusted to use these changes in the report on
the Data tab.
Maybe the anemometer is the same, but I would guess everything else is different.
-
That's good to know and thank you for mentioning that. That explains too why the software versions on the LaCrosse website are different for the 2812 and 2810. Like you say the anemometer maybe the same (and possibly the rain gage) but the thermo/hygro and displays are not.
-
I just finished replacing my 2810 with the 2812 from Costco and it went very smoothly. The rain problem appears resolved, as it now measures 0.01" per tip. (I think it reports a little slower, but that is OK.)
The anemometer appears to have been redesigned, and is a little bigger. I have attached a couple pictures showing the difference. (Maybe it will read the direction more accurately in light winds.)
The only part that seems identical is the wireless USB receiver.
-
grr. I have a 2812 bought from costco a couple weeks ago and in a major downpour yesterday, it read like 3.6" over a 10 hour period, when most of the nearby stations on wunderground were reading notably less than that, like 1.5"-2". now, our rainfall varies widely within a short distance as I'm close to the west coast, up 300' and this area is full of redwood forested canyons between 2000-3000' ridges that are rain traps. average annual rainfall varies more than 2:1 over a 10 mile distance.
