e) Diode Test
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
• Turn the DMM on and select measuring function
.
• Plug the red measuring lead into the V measuring
socket (9) and the black measuring lead into the
COM measuring socket (8).
• 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.
• Check the measuring lines for continuity by con-
necting both measuring prods with one another.
The value must be approximately 0 V.
• Now connect the two measuring prods with the
object to be measured (diode).
• The display shows the continuity voltage “UF” in
volt (V). If “OL” appears, the diode is measured in reverse direction (UR) or the diode is defec-
tive (interruption). Perform a counter-pole measurement to check.
• After measuring, remove the measuring lines from the measured object and turn the DMM off.
