Continuity Measurement - Clas Ohlson UT132E Bedienungsanleitung

5.5 Continuity measurement

1. Set the multifunction selector
to .
2. Connect the black test lead to
COM and the red test lead to
Ω mA.
3. Switch on the multimeter
using [ ].
4. Connect the ends of the test
leads to the ends of the cables
to be tested.
- No break in the cable:
The buzzer sounds
continuously if
the resistance is <10 Ω.
- Break in the cable:
The buzzer does not
sound if the resistance is
>70 Ω.
5. Switch off the multimeter
using [ ].
Warning!
Make sure that the circuit to be tested is not conducting any current before testing for
continuity.
Take extreme care when using this instrument on an inductive component such as
a transformer, relay coils and the like, and make sure they have been discharged
beforehand. High voltage may be induced at the measuring points if an open circuit
occurs.
To avoid shocks, you must be CAREFUL when working with voltages higher than
60 VDC or 30 VAC RMS. Voltages higher than this pose a risk of heavy electric
shocks.
Note: The open-circuit voltage is around 2.3–2.5 V.
