Measurement Operation(7)
l
The open-circuit voltage is around 3V.
l
When diode testing has been completed, disconnect
the connection between the testing leads and the
circuit under test, and remove the testing leads away
from the input terminal of the Meter.
Testing for Continuity
To test for continuity, connect the Meter as below:
1. Insert the red test lead into
V
terminal and the black
test lead into the
COM
terminal.
2. Set the rotary switch to .
3. Connect the test leads across with the object being
measured.
4. The buzzer does not sound if the resistance of a circuit
under test is 70
The tested circuit resistance value simultaneously
shows on the display and the unit is .
Note
l
When continuity testing has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing
leads away from the input terminal of the Meter.
