Measuring Procedure
1. Connect the black measuring cable to the COM input (4) and
then connect the red measuring cable to the V/Ω/
input (5).
2. Then set the rotary function switch (6) to the measuring range
.
3. Press the FUNC./HOLD key (2) until
display.
4. Connect the measuring cables to the component you intend to
check and read the value from the display.
Notes:
 Connect the red measuring cable to the anode (The end of the
diode not marked with a ring) and the black measuring cable
to the cathode.
 If a value of up to 3 V is displayed, the component is functional
in forward direction. The forward voltage is displayed. If the
overflow indicator "OL" is displayed, the diode is defective.
 Now turn the diode around (red + to the cathode and black - to
the anode). If the overflow indicator "OL" is displayed, the
diode correctly blocks. It is functional in reverse direction. If
the unit displays any voltage, the diode is defective.
