WebApr 7, 2024 · Method 2 Checking a Capacitor using Multimeter without Capacitance Setting. Most of the low end and cheap Digital Multimeters do not include Capacitance Meter or Capacitance Settings. Even with these Multimeters, we can test a Capacitor. Remove the Capacitor from the circuit or board and make sure it is completely discharged. WebAug 30, 2024 · If Line 1 to R = 144 Volts (approx.) (120 + 24), the low voltage is out of phase and low voltage polarity must be reversed. Low Voltage Polarity can only be reversed at the transformer terminals. Apply Step 1 or Step 2 below – don’t do both or polarity will not be changed. Remove both high voltage wires from the transformer and swap them.
