d. Select the range to enter current measurement
Note:
When only the figure “OL” is displayed, it indicates over range 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.
In“ AC ” mode, only can input “AC ”, if not, will damage the meter.
Resistance Measuring
WARNING!
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, enter the
Ω
measurement
