Testing For Continuity - UNI-T UT58A Operating Manual

Model UT58A/B/C: OPERATING MANUAL
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.
Warning
To avoid harms to you, please do not attempt to input
voltages higher than 60V DC or 30V rms AC.
To avoid damages to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before testing for continuity.
To test for continuity, connect the Meter as below:
1. Insert the red test lead into Hz V
V
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 buzzer sounds continuously if the circuit is in
good condition with resistance value 10 .
The measured value shows on the display and the
unit is .
