l Connect the test leads 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.
l When diode testing has been completed, disconnect the connection between
the testing leads and the circuit under test.

The Model UT33C/UT33D: Testing for Continuity
To test for continuity, connect the Meter as below:
1. Insert the red test lead into the VΩmA 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.
