4.4.5. Continuity test

CAUTION

Before taking in circuit continuity test, remove power from the circuit being

tested and discharge all capacitors.

Fig. 7: Continuity test

1. Turn the selector on

2. Insert the black test lead in the COM jack and the

red probe in the V+/Ω jack (Fig. 7).

3. Connect the test lead to the circuit under test; the

resistance value will be displayed (automatic

range detection).

4. Should you get the message "

O.L

" it means that

the detected voltage exceeds the limits which the

instrument can measure. In this case stop the

measurement by disconnecting the test leads

from the circuit under test to avoid risks for

yourself and for the instrument.

5. If the buzzer beeps during continuity tests it

means that the resistance value is lower than

50Ω.

6. If you want to activate the HOLD, REL and

RANGE functions refer to chapter 4.2.
