Warning
To avoid harms to you or damages to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000VDC / 750VAC RMS although
readings may be obtained.
AC voltage measurement
The AC voltage ranges are: 4.000V, 40.00V, 400.0V
and 750.0V. To measure AC Voltage, connect the Meter
as follows:
1. Insert the red test lead into the HzVΩ terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to V and press SELECT
button to select AC measurement mode.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display,which
is effective value of sine wave (mean value response).
