Note:
a.
Do not measure the current higher than 10A At Range 10A and higher than 400mA At Ma Range.
b.
Do not connect the test lead to any circuit in parallel when the test lead is inserted in the
current input terminal, otherwise it is possible to damage the instrument or endanger the safety of
the users. Cut the connection between the test lead and tested circuit at once after measurement.

Max input current: 10A (less than 15 seconds).
Overload protection: 0.5A/250V fuse, 10A/250V fuse.
Frequency response: 40-100Hz.
Duty Circle Indication: (0.1%-99.9%)

1.
Turn the function/range selection knob to
Ω
, insert the red and black test lead separately to
V/
Ω
/Hz and COM input terminal.
2.
Connect the test lead to the tested resistance in parallel, the tested resistance value will be
displayed on LCD.
3.
Auto Range mode is preset when turning on, press “RANGE” button to switch to Manual Range
mode.
4.
If “OL” is displayed on LCD, it indicates the tested resistance value has exceeded the present
range limit, please select the higher range to complete the measurement.
Note:
a.
When measuring the In-circuit resistance, be sure all the Power of the tested circuit Has been
turned off and all capacitors are fully discharged.
b.
It will cause the reading incorrect to input any voltage when measuring the resistance.
If the voltage exceeds 250V, over-range protection voltage, it is possible to damage the instrument
and endanger the safety of the users.
