The device is especially useful for measuring very large capacitances up to 600 mF. Electrolyctic capacitors are measured at 120 Hertz with ESR measured at 100 kHz according to regular electrolytic capacitor test conditions. The test frequency is reduced to 25 Hertz when using the ‘Large Capacitance’ mode, allowing to evaluate very large capacitances with reasonable accuracy. The LCR-Reader-MP offers a wide range of test frequencies for optimal test conditions. The frequencies are 25, 100, 120 Hz, 1, 10, 20, 30, 40, 50, 60, 75 and 100 kHz.
