An easier way to test these capacitors for value, leakage and ESR is with an instrument that performs all three functions, such as a Sencore LC75. A benefit of using the Sencore is that leakage can be checked at the operating voltage of the capacitor, up to 600 V with the Sencore LC75, and up to 1000 V with the Sencore LC101. | An easier way to test these capacitors for value, leakage and ESR is with an instrument that performs all three functions, such as a Sencore LC75.

Few vintage RC bridge testers offer Capacitor Leak testing as well, like EICO 950B, Heathkit IT-11, Heathkit IT-28, Heathkit C-3 Condenser Checker etc. These instruments supply up to 600V DC (IT-11) and indicate the leakage current in a Magic Eye Tube. A Closed eye indicates excessive leakage current. | |||
