The ESR (Equivalent Series Resistance) of Capacitors
The problem is that when the capacitor is shorted its ESR will be almost 0Ω, and a basic ESR meter will tell us that the capacitor is perfect. For this reason, we should not only measure the ESR in order to judge a capacitor as good, but we should also measure its capacitance and continuity with a multimeter.
Electrostatic fieldmeter
An electrostatic fieldmeter, also called a static meter is a tool used in the static control industry. It is used for non-contact measurement of electrostatic charge on an object. It measures the force between the induced charges in a sensor and the charge present on the surface of an object. This force is converted to volts, measuring both the initial peak voltage and the rate at which it falls away.
