In a circuit, a good diode should still produce a forward
voltage drop reading of 0.5V to 0.8V; however, the
reverse voltage drop reading can vary depending on the
resistance of other pathways between the probe tips.
Connect the test clips to the proper terminals as said
above to avoid error display. The LCD will display “
1
”
indicating open-circuit for wrong connection. The unit of
diode is Volt (V), displaying the positive-connection
voltage-drop value.
When diode 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.

To test for continuity, connect the Meter as below:
Insert the red test clip into the
terminal and
the black test clip into the
COM
terminal.
Set the rotary switch to .
Connect the test clips across with the object being
measured.
The beeper comes on continuously when the test
resistance <120 .
The Meter displays the value of the test resistance.
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.
