Even if you have no need for an ESR meter, [W2AEW]’s video below is a solid introduction to how ESR is determined. The circuit itself comes from EEVBlog forum user [Jay-Diddy_B] and is about as ...

No mention of the actual test current and 12V is a lot for compliance voltage, no in-circuit testing for this meter. Many ESR meters use a transformer to achieve high test-current and diode-clamp ...

It can also measure ESR in-circuit, which is a great timesaver when troubleshooting. The ESR function can also be used to measure the resistance of things like transformer windings and coils. It shuts ...

Designed to test components at frequencies up to 10 kHz, the Model 885 Synthesized In-Circuit LCR/ESR handheld meter is claimed as the most accurate meter on the market. The battery ...
