I've heard of at least one other meter which keeps relay contacts closed across the terminals, until the "test" button is pressed. Some dedicated capacitor testers simply use diodes back-to-back across the terminals for protection, which effectively limit the usable signal to +/-0.6v and anything over this is shorted. ![]() Multimeter has overload protection: 600V-PTC. Measuring capacitance is more complicated than other modes because reference components may need to be switched in/out, or the meter may need to sample and electrically "kick" the capacitor, etc. Usually these are accessible by removing the battery door, or on some models, the outer enclosure. Typically a traditional glass or ceramic fuse will fail, preventing all operation. But violating the limitations of the meter can indeed result in temporary or permanent damage. Most manufacturers are void of operating details. All meters are different, so consult the documentation of yours for any relevant information. Applying large voltages to this can damage components. Calculation from the reference inductor value = capacitance value.īoth of these require small signals and small voltages. ![]()
