WebMay 8, 2012 · First, grab your digital multimeter. (Need a new one? Check out our multimeter page.) 2. Then, set the dial to AC Voltage or VAC. Note: the maximum voltage for each set, household current is approximately 120 volts, set the dial accordingly. 3. After that, connect the probes to the proper inputs: COM for the black lead and Volts for the red lead. WebApr 10, 2024 · Capacitors go through a cycle of charging and discharging. One reliable way to test a capacitor is to use the ohmmeter function of a multimeter. Checking the capacitor’s resistance will tell us if it’s in working order. To do this check, we connect the ohmmeter’s probes to the capacitor’s terminals. WebFeb 23, 2024 · 1. Set the multimeter to Ohms or Resistance. Turn the meter on if it has a separate power switch. When multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites. When there is little resistance, there will be a great deal of continuity, and vice versa. fisher clinic the pas
