Battery Power Consumption Testing When The Engine Is Off - UNI-T UT106 Operating Manual

E. Battery Power Consumption Testing when the
Engine Is off
The test is carried out to find the amperage of the power
consumption of the battery when both the ignition key
and the engine are off. The test is helpful for the
determination of the additional consumption of the battery,
which may finally lead to the exhaustion of the battery.
1.
Turn off and close the ignition key and all its
accessories.
Make sure that the bus, engine louver and room lights
have been turned off and closed.
2.
Set the rotary switch to
As prompted at the LCD connect terminal, insert the
red test lead into the A terminal and the black one
into the COM terminal.
3.
Cut off the link between the positive pole of the battery
and the cable and connect the test lead probes to the
circuit. (Connect the red test lead probe to the positive
pole of the battery and the black one to the negative
pole of the battery.)
Warning
Do not start the engine of the automobile in testing,
or the meter will be damaged.
4.
Read the reading of the tested current directly from
the display with the normal current being about
100mA. For the special supply of currents (when
the engine is off), please refer to the automotive
servicing manual. If there emerges any additional
current, do necessary servicing.
Warning
A frequency-modulated radio or clock needs a
current supply of 100mA.
