11.5 Diode test
Make sure that all the circuit parts, switches and components and other objects of measurement are
disconnected from the voltage and discharged�
1� Turn the DMM on and select measuring function
2� Plug the red measuring lead into the V measuring socket (9) and the
black measuring lead into the COM measuring socket (8)�
3� Press "MODE" button to switch measurement functions� The symbol
for diode test now appears in the display� Pressing this button again
takes you to the next measuring function�
4� Check the measuring lines for continuity by connecting both measur-
ing prods with one another� The value must be approximately 0 V�
5� Now connect the two measuring prods with the object to be meas-
ured (diode)�
6� The display shows the continuity voltage "UF" in volt (V)� If "OL" ap-
pears, the diode is measured in reverse direction (UR) or the diode
is defective (interruption)� Perform a counter-pole measurement to
check�
7� After measuring, remove the measuring lines from the measured
object and turn the DMM off�
