So , meter on the bench , no probes , no powerfull electric field nearby ( everything was shut down )
At first was 0.000 , and then slowly is drifting up ( in maybe 30min ) . Doesn't matter if is on or off . With leads connected is much faster and bigger . This offset is adding when I measure a real capacitor .
This is not something heating up inside , it is like some capacitor in the measurement path is charged by external electromagnetic field .
If I switch the rottary selector to off and then on again to capacitance nothing is changing .
To zero out this offset I have to cycle through cap manual ranges or to switch to resistance and back ...
I see that you are curious about the shim , my multimeter was bought from Welectron with it already installed ( I looked inside ) . And is working just fine ... for now
