The NCM-20 capacitance meter is designed to measure the capacitive of units or capacitor banks without having to remove interconnecting wires from units. This measuring system is designed to locate the loss of internal fuses in capacitors. The NCM-20 is portable and operated using built-in batteries with an easy to use display unit. The capacitance measurement is reproduced on a 3½ LCD (digital) display unit. The unit includes an AC current clamp.
