Checking Capacitor Under Load. Checking capacitor while under load YouTube When testing a run capacitor, many techs pull the leads off and use the capacitance settings on their meters to test capacitors Using this method on maintenance calls pretty much eliminates failed dual capacitor service calls for our maintenance customers

For a dual-run capacitor, you would check between the Common terminal and whichever side (Fan or Herm) you wish to test Set your clamp meter to amps and take an amp draw reading of the motor start winding wire connected to the capacitor, and note the reading

the capacitor and the start terminal #3 - Measure the voltage applied across the capacitor #4 - Multiply amps times 2652 and then divide by the voltage (Across the capacitor) #5 - Compare measured capacitance against the capacitor rating ad tolerance to see if it measures within specification The test under load is an accurate measure of. When you're constantly checking capacitors as a matter of regular testing and maintenance, testing the capacitors under load (while running) is a great way to confirm the capacitor is doing its job under real load. When testing a run capacitor, many techs pull the leads off and use the capacitance settings on their meters to test capacitors
How to check capacitor Capacitor testing YouTube. We need to make sure we are accurate when advising a repair Now, set your meter to volts and take a reading across the capacitor that will give you the back electromotive force of the motor; note the reading
