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 new dual-purpose instrument combines high-voltage insulation testing up to 20 GΩ with comprehensive electrical measurement capabilities for field electricians.

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 ...

It’s remarkable how tiny electronics have become. Heaven knows what an old-timer whose experience started with tubes must think, to go from solder tags to SMD in a lifetime is some journey. Even the ...
