WebMagnify and measure the start up voltage spike before the capacitor begins to charge. This voltage change value will be your ESR. If you want to measure the ESR using a constant current load, set the load to 1A. Charge your capacitor to its rated voltage and remove from the supply. Measure the voltage on the capacitor. Web20 feb. 2024 · There are multiple ways for testing an AC capacitor like a digital multimeter, voltage meter, and ohmmeter. Before testing a capacitor, make sure to disconnect the capacitor from the circuit. And short the terminals of the capacitor using a resistor of at least 1k. Try to avoid contact with the terminals during the process.
