To Measure True RMS AC Voltage:
1. Plug the black test lead into the COM port and the red test
lead into the V
Ω
Hz port.
2. Set the rotary switch to the V position.
3. Push the blue button until
AC
is shown on the display.
4. Connect the meter in parallel with the load or circuit.
5. Measure AC Voltage.

Auto Power Off (APO)
The APO sign on the LCD panel indicates the meter is working
in the Auto Power Off mode. If the meter idles for more than 10
minutes, the meter automatically turns the power off. When this
happens, the state of the meter is saved the meter can be
turned back on by pushing any key switch or changing the
rotary mode. The meter will give an alarm 15 seconds before
the meter automatically turns the power off. To disable the auto
power off function, power-up the meter while pressing either
the range or Hz switch.
Hz sensitivity
The sensitivity in the Hz mode (pushing key) is 1/10 of full
scale range. The accuracy is same as Frequency mode. The
measuring frequency is from 40Hz up to 1KHz.
