4. How to do Self-Calibration?
4.1. Why need to do self-calibration?
The accuracy of Most DMM is assured under the condition that operating environment is within
“23±5°C” and the humidity “<75%RH”, otherwise the temperature co-efficiency should be taken into
consideration. For this DMM, if you perform self-calibration, the accuracy will be kept and the affection
of environment changes will be eliminated.
4.2. How to self- calibrate a multimeter?
1) Rotate the
selector switch
to
"
