How does a capacitor test work?
A computer controls the instruments to perform the tests automatically. One set of switches is used to apply the test voltage to each capacitor in turn; a second set of switches connects each capacitor to the electrometer’s picoammeter input after a suitable soak period.
Why is it important to test capacitors regularly?
Capacitors are electronic components that store electricity, and they help regulate current flow in a circuit board. It is important to test the capacitors regularly because if they fail or become damaged, other components on the circuit board can be affected. Knowing how to properly test them can help you diagnose and correct problems quickly.
How do you test a capacitor?
