Barometer adjustment on Heathkit ID-4001
« on: December 04, 2017, 10:28:52 PM »
I'm tuning up an old heathkit ID-4001 and cannot lay my hands on the manual and documents I had when I built the thing.  Considering how long ago I took it off line and stored, it there is little wonder as to why.

I need to tweak the barometer, if it is even functional any more.

I know there are two openings on the back, one for coarse and one fine adjustments.

Can anytell me off hand which (upper or lower) is the coarse adjust and of course the other would be fine.  I recall that it takes patience to do this since the update rate on the system is pretty slow.

Thanks .Dale

What a great forum!  Thanks for your help.  If I dig too much more in my 'archives' my wife will insist that I start cleaning and throwing things away.

You saved me from a dreary week.
