How do you read wastco cappy capacitor tester?

To read a Wastco Cappy capacitor tester, first connect the capacitor to the tester's leads, ensuring correct polarity if it's a polarized capacitor. Turn on the device and select the appropriate capacitance range if necessary. The display will show the capacitance value in microfarads (µF), and you can compare this value to the capacitor's rated capacitance to determine if it's functioning properly. Additionally, check for leakage or shorts as indicated by the tester's output.
