WebbAn ESR meter is a two-terminal measuring tool with the primary purpose of measuring the ESR of capacitors. Usually, bad capacitors have high ESR readings that you can’t measure with a regular digital capacitance meter or multimeter. That’s not all. You can use an ESR meter without removing the capacitors from your circuit. Here’s the best part. Webb23 juli 2024 · By measuring the phase difference, you can work out the capacitance (or inductance) of the component at that frequency, as well as any equivalent series resistance (ESR) of capacitors. Although some multi-meters can measure capacitance or inductance, they will usually only do it at one frequency. An LCR meter will allow you to vary the …
