LPF ACV (Picture 7)
AC Voltage Measurement
Note:
Do not input voltage above 1000V. Although it is possible to measure higher
voltage, it may damage the meter.
Be cautious to avoid electric shock when measuring high voltage.
After completing the measurement, disconnect the test leads from the circuit
under test.
When the measured voltage is above 30V, the LCD will display the high voltage
alarm prompt “ ”.

1) Insert the red test lead into , , or jack, and black test lead
into the COM jack.
2) Turn the function dial to V~ or position.
3) Short press the SELECT button to switch to AC voltage measurement if
required, and connect the test leads with the measured load or power supply
in parallel.
Voltage Frequency Measurement
1) When the function dial is in the AC voltage, short press Hz or Hz/INRUSH
button to enter the frequency measurement mode.
2) Short press Hz or Hz/INRUSH button again to exit frequency measurement
mode.
LPF ACV Measurement
1) When the function dial is in the AC voltage position, long press SELECT button
to enable LPF ACV function. LPF can measure combined sine wave signals
produced by inverters and variable frequency drives, as shown below.
2) After enabling the LPF ACV function, short press the Hz/INRUSH button to
enter the frequency measurement mode.
3) Short press the Hz/INRUSH button again to exit the frequency measurement
mode.
