Curious, Section 5.7.3.4 Hourly Rainfall Icon in the HP2551 Manual shows the increment increases as recorded in Inches. Our Display Console is set to metric. We recorded 30 mm of rain over 9 hours this morning however the Display Console gauge has only ever shown 0 to 0.2 mark as per the manual.
In just four months we have recorded 248.9 mm of rain since April 08, 2020. The joy of living in a Rain forest!
Have any of you ever had your Display Console gauge any higher than the lowest marking?
I wonder is it programmed for Inches only?
