7.CAPACITOR
1) Remove the lead wires from the capacitor terminals, and then place a probe on the
capacitor terminals as shown in Fig.3.
2) Observe the deflection of the pointer, setting the resistance measuring range of the
multimeter to the maximum value.
* The capacitor is “good” if the pointer bounces to a great extent and then gradually returns to
its original position.
* The range of deflection and deflection time differ according to the capacity of the capacitor.
