5.5. Testing for Continuity
To test for continuity, connect the Meter as below:
1. Insert the red test clip into the

°
))) terminal and the
black test clip into the COM terminal.
2. Set the rotary switch to
°
))).
3. Connect the test clips across with the object being
measured.
4. The beeper comes on continuously when the test
resistance <20
Ω
.
5. The Meter displays the value of the test resistance.
Note:
*
The LCD displays “1“ indicating the circuit being tested is
open.
* When continuity test has been completed, disconnect the
connection between the testing clips and the circuit under
test and remove the testing clips away from the input
terminals of the Meter.
5.6. Transistor hFE Measurement
To measure transistor, set up the Meter as follows:
1. Check that the transistor is PNP or NPN type.
2. Insert the transistor to be measured to the corresponding
Transistor Jack.
3. The Meter displays the tested transistor´s nearest value.
Note:
* When transistor measurement has been completed,
disconnect the connection between the testing clips and the
circuit under test and remove the testing clips away from the
input terminals of the Meter.
