Method 1. Test a Capacitor using Digital Multimeter – Resistance Mode To test a capacitor by DMM (Digital Multimeter) in the Resistance “Ω” or Ohm mode, follow the steps given below. Make sure the capacitor is fully discharged. Set the meter on the Ohmic range (Set it at least on 1000 Ohm = 1kΩ).
Make sure the capacitor is fully discharged. Set the meter on the Ohmic range (Set it at least on 1000 Ohm = 1kΩ). Connect the multimeter probes to the capacitor terminals (Negative to Negative and Positive to Positive). Digital multimeter will show some numbers for a second. Note the reading.
Continuity mode can be used to test if a capacitor is short-circuited or has an open circuit. Steps: Set the multimeter to continuity mode. Discharge the capacitor. Place one probe on each terminal of the capacitor. If the multimeter beeps or shows continuity, the capacitor may be shorted.
Steps: Set the multimeter to the capacitance (C) mode. Ensure the capacitor is discharged to avoid any electrical hazards. Connect the multimeter probes to the capacitor terminals, observing polarity if applicable. Read the capacitance value displayed on the multimeter.
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.
However, to be useful, their capacitance value, voltage rating, temperature coefficient, and leakage resistance must be characterized. Although capacitor manufacturers perform these tests, many of the electronics manufacturers who build them into their products also perform some of these tests as quality checks.
