12. Results are:
Range 400mV - resistance is from 1.4 to 3.1 MOhm
Range 4V - resistance is from 13.5 to 15.1 MOhm
Range 40V - resistance is from 10.4 to 10.7 MOhm
Range 400V - resistance is from 9.9 to 10.2 MOhm
Range 1000V - resistance is from 9.94 to 10 MOhm
When i Power off METEX from Power button resistance slowly(2 min) raise to 38MOhm.
Set the function on Resistance and open probe, meter show around 4.6 MOhm again.
When on display blink indicator for low battery then stable resistance 4.6MOhm began to fluctuate.
13. The problem began before two month and continuous still.
I think that i have a problem with voltage of DMM-P(page 19 Analog DMM Part) and then maybe with DVDD. DMM-P is come from Power part but i haven't power part circuit for my meter. This from page 21 Power Part isn't the same. Maybe someone capacitor in Power part.
