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
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.
