To avoid damage to the meter, check the meter's fuse before proceeding.
Use the proper terminals function, and range for your measurement.
Never place the probes In parallel with a circuit or component when the
leads are plugged into the current terminals.
The meters current ranges are 600.0µA, 6000µA, 60.00mA, 600.0mA, 6.000A
and 10.00A.
To measure current (set up the Meter as shown in Figure 3-6):
1. Turn off power to the circuit. Discharge all high voltage capacitors.
2. Set the rotary switch to the µA, mA or A range.
3. Press the SELECT key to select DCA or ACA measuring mode.
4. Connect the black test lead to the COM terminal and the red test leads to the
mA terminal for a maximum of 600mA. For a maximum of 10A, move the red
test lead to the A terminal.
5. Break the circuit path to be tested.
Touch the black probe to the more negative side of the break; touch the red
probe to the more positive side of the break. (Reversing the leads will give a
negative reading, but will not damage the Meter.)
6. Turn on power to the circuit; then read the display. Be sure to note the
measurement units at the right side of the display (µA, mA or A). When only the
figure "OL" displayed, it indicates over range situation and the higher range has
to be selected.
7. Turn off power to the circuit and discharge all high voltage capacitors.
Remove the Meter and restore the circuit to normal operation.

3.2.9 PC Link The meter has serial data output function. It can be connected
with PC by USB interface, so the measured data can be recorded, analyzed,
processed and printed by PC. Before use this function, you need install the PC-
Link software and USB driver in your PC.
Press the Hz% key while turn on the meter, the meter enter PC-Link mode, the
symbol "PC-LINK" will appear on LCD, and the serial data output function is
active.
PC-LINK SOFT OPERATING MANUAL
1. Make sure the two Install USB driver and Install software files in the attached
CD successfully installed before any measurement.
2. Keep the meter in "OFF" status, pressing the Hz% key while turn on the
meter and the symbol "PC-LINK" will appear on the LCD if the serial data output
function is active. (To disable the auto power off function, hold down the
SELECT key and Hz% key while turning the meter on.)
NOTE: If we want to enable the serial data output function during measuring,
we have to turn off the meter first, then operate according to step2.
3. Connect the meter's OPTICAL PORT and computer USB port with the USB
line.
4. Run the PC-LINK software, click the SET menu. Select the System Set. Then
select the proper COM port in the Serial Port Select. As for the proper COM
port, we can view it in the Device Manager by following these steps:
