- Turn the DMM on and select measuring range
- Insert the measuring cables in line with the model into the corresponding measuring sockets as
shown in the table.
- Check the measuring leads for continuity by connecting both measuring prods to one another. After
that the value must be approximately 0 V. The open-circuit voltage is approx. 3 V.
- Now connect the two measuring prods with the object to be measu-
red (diode).
- The display shows the continuity voltage in volt (V).
-
If "OL" is indicated, the diode is measured in reverse direction or the
diode is faulty (interruption). Perform a counter-pole measuring for
control reasons. The red measuring lead corresponds to the positive
pole (anode), the black measuring lead to the negative pole (cath-
ode). A silicone diode has an on-state voltage of approx. 0.5 – 0.8 V.
- After measuring, remove the measuring leads from the measuring object and turn the DMM off. Turn
the rotary switch to the position "OFF" or turn the device off via the "POWER" switch.
f) Continuity check
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.

- To activate the acoustic continuity tester function, press the button "SELECT" (3). Pressing this but-
ton again takes you back to the first measuring function (diode test) etc.
