AC VOLTAGE MEASUREMENT
WARNING
!
Do not input voltage over 1000Vrms. It is possible to measure higher
voltage. However, it may cause damage to the meter. Be cautious to
avoid electric shock when measuring high voltage.
1. Switch the function dial to
V
position (range: 6V/60V/600V/1000V).
2. Connect the common test lead to COM terminal, then insert the red test lead into the to

terminal.
3. Connect the leads to the correct test points in the circuit to measure voltage.
NOTE:
•
Before using the device, it is suggested to measure a known voltage for verification.
•
The meter input impedance is about 10MΩ. This load may cause measurement error when
measuring the high impedance circuit. In most cases, if the circuit impedance is under
10kΩ, the error can be ignored (<:0.1%).
•
The input impedance of DC mV scale is infinite ( > 1000MΩ), and it does not attenuate
when measuring weak signals, so the measurement accuracy is high. However, when the
test leads are disconnected, there may be a value on the screen, which is normal and will
not affect the measurement result.
•
Readings of AC measurement are true RMS.
•
At AC voltage position, short press {<2s) SEL/REL button to enter frequency measurement.
Frequency measurement range: 45Hz-1kHz (for reference). Min measurement amplitude:
10% of voltage range.
