
Connect the red test prod with the drain
(+), the black test prod with the source
(-) of the diode.

The value of the bias-voltage (mV) is
shown in the display. In case of wrong
polarity, figure "OL" will be shown in the
display. Repeat the test with changed
poles.
Continuity test

Connect the black cable to "COM"-hub
and the red measuring-cable to the"
mA/Ω/BATT"-hub.

Position the center switch to "

Connect the test leads across the circuit
to be tested.

If the resistance is less than 20W, the
built-in buzzer will sound.
Battery test

Connect the black cable to "COM"-hub
and the red measuring-cable to the"
mA/Ω/BATT"-hub.

According to the rated voltage of the
battery to be tested, set the range switch
in the corresponding BATT range
position.

Connect the test leads to the two
terminals of the battery to be tested.

Read the working voltage of the battery
on the display.

In the ranges "BATT 1,5V" and "- 9V" the
battery to be tested is charged by an
internal resistance; so you get practical
information on the condition of the tesed
battery.
