3.8. VAHZ Function
When voltage or current measurement mode is selected, the VAHz funtion is available. Push HZ
key to select this frequency measurement mode. The frequency is measured by auto ranging. The
maximum frequency range is 60KHz. The sensitivity of signal input is 5% full scale of signal in
voltage or current mode typically.
