Diode Test Function - Westfalia Wetekom 85 94 54 Instruction Manual

The second way is to press "REL" while the probes are shorted out.
This way, the resistance of the cables is automatically deducted
from the measuring result. "REL" appears in the display as confir-
mation.
Ensure good contact between the probes and the testes object
during the resistance test. Dirt or other forms of contamination on
the test probes or leads of the resistor may result in incorrect read-
ings.
If the measured resistance value exceeds the measuring range, the
overflow symbol "0.L" is displayed.

4.4 Diode Test Function

With this function you can test diodes and other semiconductors for
continuity and blocking function and determine their functionality.
Please notice!
Never connect the measuring probes to a power source while using
this function. This may destroy the unit.
Do not perform measurements on voltage-carrying components or
circuitry and make sure all capacitors are fully discharged before
performing measurements.
Procedure for Testing Diodes
1. Make sure the component or circuit to be measured is voltage-free.
2. Connect the red probe to the V;
black probe to the COM input (12).
3. Set the rotary function switch (10) to "
now set to the resistance measurement mode. Therefore, press
"Mode" (4) once to switch to the diode test function. This is con-
firmed by the
