Note

When the meter is set to measure frequency and there is no input signal (i.e., the input terminals are open), the meter may read approximately 25 kHz (rather than zero). This is due to internal capacitive pickup ofthe inverter power supply into the high-impedance, input circuitry. With source impedance of< 2 kW, this pickup will not affect the accuracy or stability of the frequency reading.
