Ver 4.4 precipitation offset error

Post by Tman »

Davis Pro console shows 0.8 mm total rain today but MB shows 1.1 mm. It seems each time MB records extra 0.1 mm when it rains. Something fishy here.

But that's not an extra exact 0.1mm (as such) as it may be rounded up or down and if one knew the exact difference per tip then something might be more obvious? Are your corresponding configuration settings correct relative to the rain gauge tipper type (metric v imperial etc)

Never seen this with older version of MB. Checked rain resolution settings at Davis console, it is 0.2 mm, similar to MB. Time difference between MB and console is less than 1 minute.

As it seems that there has been 2 "drops", and two times one drop yesterday. In metric it equals 2*0.2mm + 0.2 mm + 0.2 mm = 0.8 mm. Now MB shows 0.5 mm + 0.3 mm + 0.3 mm = 1.1 mm. So it could be metric/imperial conflict. 2*0,254 mm + 0.254 mm + 0.254 mm which matches above numbers with roundings.

GUI shows metric 0.2 mm rain resolution. Is there any way to double check that in settings?

That does have all the hallmarks of a imperial/metric conflict somewhere?

"Now MB shows 0.5 mm + 0.3 mm + 0.3 mm = 1.1"

0.254 & 0.254 = 0.5 rounded down
0.254 = 0.3 rounded up

Agree. But where could it be? Maybe I force imperial units to ISS transmitter at MB and then back to metric... Any other idea?
