The Meter's current ranges are 600.0
µ
A, 6000
µ
A, 60.00mA, 600.0mA, 6.000A and 10.00A.
To measure current:
1)
Turn off power to the circuit. Discharge all high voltage capacitors.
2)
Set the rotary switch to the
µ
A, 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 (
µ
A, mA or A). When only the figure "OL" displayed, it indicates
overrange 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/DUTY
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/DUTY
key while turn on the meter and the
symbol “
PC-LINK
” will appear on the LCD if the serial data output function is active.
3)
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.
4)
Connect the meter’s OPTICAL PORT and computer USB port with the USB line.
5)
Run the
PC-LINK
software, click the
SET
menu. Select the
System Set
. Thenselect the proper
COM port in the
Serial Port Select
. As for the proper COMport, we can view it in the Device
Manager by following these steps.
•
