4) Press the function key MENU (Menu) to enter one menu
item in which basic DC voltage measurement can be modified.
Press the cursor keys 0;l;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, and press F4 to close the window
of additional function.

Attention:
• Do not input a voltage higher than 1 OOOV. 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.

5. AC and DC Current
1) Insert the red test lead into the µAmA or A terminal and the
black test lead into the COM terminal.
2) Set the rotary switch to the position as shown in Figure 7.
Press the key SEECT to select the required AC or DC to
be measured. Connect the test leads to the test circuit in
series.
3) Directly read the measured current 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 or DC current 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, and press F4 to close
the window of additional function.
.&. Warning
• Before connecting to the test circuit in series, turn off the
power to the circuit first and discharge all the high-voltage
capacitors.
• Use proper input terminals and functions for measurement.
If the current size cannot be estimated, the range of large
current should be measured first.
• When the test lead is inserted in the input terminal of current,
do not connect its test prod to any circuit in parallel, it will
blow the fuses within the meter and damage the meter.
