e) Diode Test
ƽ
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 connecting
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 defective (interruption). Perform a
counter-pole measurement to check.
- After measuring, remove the measuring lines from the measured object and turn the DMM off.
f)Continuity test
ƽ
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 .
- Press “MODE” button twice to switch measurement func-
tions. The symbol for continuity test now appears in the
display. Pressing this button again takes you to the first
measuring function etc.
- Plug the red measuring lead into the V measuring socket
(9) and the black measuring lead into the COM measuring
socket (8).
- Acontinuity value of less than 50 Ohm is identified as con-
tinuity; in this case a beep sounds. The impedance value is
displayed up to 399.9 Ohm.
- If “OL” (overload) appears on the display, you have excee-
ded the measuring range or the measuring circuit has
been broken.
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
