Figure 3-11. Continuity Test
Model 72-8720: OPERATING MANUAL
F. Testing for Continuity
Warning
To avoid harms to you, please do not attempt to
input voltage higher than 60V DC or 30V AC.
To avoid possible damages to the Meter or to the
devices under test, disconnect circuit power and
discharge all the high-voltage capacitors before
measuring continuity.
To test for continuity, set up the Meter as Figure 3-11
and do the following:
1. Insert the red test lead into the
terminal and the
black test lead into the
COM
terminal.
2. Set the rotary switch to
; press
SELECT
button
to select measurement mode and connect the test
leads across with the object being tested.
3. The beeper comes on continuously for open
conditions, that is test resistance around < 50 .
4. The display shows the tested resistance load value.
The unit is .
The
SELECT
button cycles among resistance, continuity,
and diode.
Note
l
l
Open circuit voltage around ñ1.2V and range is
400
measurement range.
When continuity testing has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove the test leads
away from the input terminals
.
