（
use 10A socket
）
d. Select the range to enter current measurement
Note:
u
When only the figure “OL” is displayed, it indicates over range situation and the higher range has to
be selected.
u
When the value scale to be measured is unknown beforehand, set the range selector at the highest
position.
u
The maximum current of mA socket is 660mA; over-current will destroy the fuse, and will damage
the meter.
u
The maximum current of 10A socket is 10A, over-current will destroy the meter, and will damage
the operator.
u
In“ AC ” mode, only can input “AC ”, if not, will damage the meter.
Resistance Measuring

When measuring in-circuit resistance, be sure the circuit under test has all power removed and that all
capacitors have discharged fully.
a. Connect the black test lead to the “COM ” jack and the red test lead to the “V/
Ω
” jack.
b. to select
Ω
