RELATED MEASUREMENT OF AC VOLTAGE AND LPF ACV (PICTURE 2)
AC Voltage Measurement
1) Insert the red test lead into
2) Turn the function dial to V~ or
3) 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.
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
