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 ...

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 ...

Fluke Corp. has introduced a new, easy-to-use utility multimeter designed to help utility workers, linemen and electricians, to quickly diagnose electrical problems. The Fluke 113 Utility Multimeter ...
