The resistance of the diode cannot be measured with the normal ohmmeter on a DMM because the voltage used may not be high enough to bias the diode. DMM’s often have a diode testing mode that supplies ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...
