Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

So, test the capacitors while the system is running for a more accurate reading, and it works doubly in your favor as a way to impress other technicians with your newly found math skills. Remember ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor or a run capacitor. Some motors will even use both.

The portable meter can also be used to make low-value, non-inductive resistor (DCR) measurements. The tester can detect a shorted capacitor in its DCR cycle and also determine its ESR value to ...

Back in 2006 I wrote about how my friend Alan Martin over at Texas Instruments had a saying: “It’s always a capacitor.” This was based on his observance that there is a lot of test equipment that goes ...
