If “OL” (overload) appears on the display, you have exceeded the measuring range or the measuring cir-
cuit has been broken. Pressing the “REL” button again switches off the relative function and activates
the auto range function.
- After measuring, remove the measuring lines from the measured object and turn the DMM off.
☞
If you carry out a resistance measurement, make sure that the measuring points you
touch with the test prods are free from dirt, oil, solderable lacquer or the like. Such cir-
cumstances can falsify the measured result.
f)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 range
.
The
diode symbol appears in the display.
- Plug the red measuring line into the Ω measuring jack and
the black measuring line into the COM measuring jack (8) .
- Check the measuring lines for continuity by connecting
both measuring prods with one another. The value must
be approximately 0.000 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 direc-
tion (UR) or the diode is faulty (interruption). Perform a
counter-pole measurement to check.
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
