range；
c．Manual range: 0.000mA  6.6mA range
00.00mA  66.00mA range
000.0mA  660.0mA range
00.00A  10.00A range（use 10A socket）
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 the tester default Auto range status, Press the key manually
