3. AC Voltage
1) Insert the red test lead into the V terminal and the black
test lead into the COM terminal.
2) Set the rotary switch to v or mv as shown in Figure 5.
Connect the test leads to the power or load under test in
parallel.
3) Directly read the measured voltage values on the display.
True virtual values are displayed for AC measurement.
4) Press the function key MENU (Menu) to enter one menu
item in which basic AC voltage measurement can be modified.
Press the cursor keys
0�0
to select menu items. The red
cursor key indicates the selected item, then press F1 to
enter the corresponding measuring mode, press F2 to
enter relative value measurement, press F3 to set dbm
resistance, and press F4 to close the window of additional
function.
&.
Attention:
• Do not input a voltage higher than 1000V. Higher voltage
may be measured but it poses risk to damage the meter.
• When measuring high voltage, special care should be taken
to avoid electric shock.
• After completing all the measuring operations, disconnect
the connection between the test leads and the circuit under
test.
• The response mode of AC coupled true RMS is adopted
for the conversion of AC with sinusoidal input calibration.
The accuracy of non-sinusoidal wave must be adjusted
based on the following:
47
For crest of 1.4-2.0, the accuracy shall be added 1.0%.
For crest of 2.0-2.5, the accuracy shall be added 2.5%.
For crest of 2.5-3.0, the accuracy shall be added 4.0%.

1) Insert the red test lead into the V terminal and the black
test lead into the COM terminal.
2) Set the rotary switch to DC V or DC mV as shown in Figure 6.
Connect the test leads to the power or load under test in
parallel.
3) Directly read the measured voltage values on the display.
