How to judge the quality of the capacitance file (CAP) of the multimeter?
A: Generally, find a capacitor with a known value, insert it directly for measurement, and the displayed value of each range should be in a 10-fold ratio; it is best to use a good metal capacitor for testing, which has stable capacity and high precision. It is not recommended to use electrolytic capacitors for testing, because electrolytic capacitors have poor stability and accuracy.
