PM2525/515 Calibration

[Fabri]

Hello,

I've this multimeter PM2525/515. After the voltage value it write always
"NC" for example 200.03NCmV. I thinks that NC is for Not Calibrate..

Someone know what i have to do?

Thanks very much

This means Not Calibrated !!!; mostly due to a dead 3V battery inside.
I think in this cas the PM25252 needs to be 'hot' and 'cold' calibrated
(the PM2525 has an internal temperature compensation for all measurements)

Hello thanks!

I'll check the battery.

Thanks
