- Set the digital multimeter dial on highest resistance in ohm section.
- Connect the probes to two ends of the unknown component (ignore polarity).
- If reading shows zero, it is an inductor.
- If reading shows some constant value other than “1” then it is a resistor.
- If reading keeps increasing and finally settles on “1” then it is a capacitor. This will happen only the first time you measure. For checking again you should shot both ends of the component for 2–5 seconds and then measure again.
- If reading shows constant “1” then it could be a capacitor or resistor. Follow following steps to identify
- Reverse the probes and check reading.
- If reading keeps increasing and finally settles on “1” then it is a capacitor and the positive, negative is according to the terminals of multimeter connected.
- If reading still shows “1” then decrease the resistance range using dial and check reading. Keep decreasing and checking till the display shows some other value than “1”. This is a resistor with the shown value.
