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.
