Direct Current (A

Connect the black cable to "COM"-hub
and the red measuring-cable either to
the" mA/Ω/BATT"-hub (upto 200mA) or
to the "10A"-hub (upto 10A).

Position the center-switch either in the
area "A
the value "10A".

Place the test prods to the spot mark
(observe the correct polarity!) and the
value and polarity are shown on the
display ( polarity of the red cable is
positive +).
Resistance measuring

Attention: Resistance measurement
may only be done with idle resistors!

Connect the black cable to "COM"-hub
and the red measuring-cable to the
"mA/Ω/BATT"-hub.

Position the center-switch in the area "Ω"
to the required range.

Place the test prods to the spot marks of
the resistor and the value is shown on
the display.
Diode testing

Attention: Diode testing may only be
done with idle semiconductor diodes!
When testing diodes inside of electric
circuits, the operating voltage of the
circuit has to be switched off.

Connect the black cable to "COM"-hub
and the red measuring-cable to the"
mA/Ω/BATT"-hub.

Position the center switch to "
)
" to the required range or to
├ ".
