Frequency or Duty Cycle Measurements (Hz%)
Do not enter a voltage above 10 V!
When measuring high voltage, pay special attention to safety to avoid electric shock or injury.
1. Turn the rotary function switch to Hz% and press
the "FUNC." key to switch over the frequency or duty cycle measurement.
2. Plug the black test lead into the COM socket and
the red test lead into the INPUT socket.
3. Connect the probes to the measuring points
(connect to the measured power supply or to the
parallel connection).
4. Read the result on the display.
