About ESR Meters

Use an ESR meter to establish the condition of a capacitor. Some models can also be used to test transistors, diodes, resistors, and MOSFETs. You can find meters that support capacitors from 1 uF to 22,000 uF, models that can be used for both out-of circuit and in-circuit testing, and you can even find a device that offers 0.01 w ESR resolution. These meters come with test leads and crocs, and most have built-in alkaline batteries. Advanced models feature software that helps to eliminate errors arising because of capacitor reactance.
