6.6mA range
00.00mA

66mA range
000.0mA

660mA range
00.00A

10A range
（
use 10A socket
）
c. Connect test leads in series with the load under measurement.
d. You can get reading from LCD.
NOTE:

When only the figure “OL” is displayed, it indicates overrange situation and the higher range has
to be selected.

When the value scale to be measured is unknown beforehand, set the range selector at the highest
position.

The maximum current of mA socket is 660mA, over-current will destroy the fuse, and will damage
the meter.

The maximum current of 10A socket is 10A, over-current will destroy the meter, and will damage
the operator.
E. Resistance Measuring
a. Connect the black test lead to the COM jack and the red test lead to the
Ω
jack.
b. Press to select
Ω
, enter the
Ω
measurement. Auto range by press key, and
Manual range by press .

00.00 KΩ 
66KΩ range
WARNING!
When measuring in-circuit resistance, be sure the circuit under test has all power removed and
that all capacitors have discharged fully.
