Note
Connect the test leads to the proper terminals as
said above to avoid error display.
The LCD will display OL indicating either open
circuit or wrong polarity connection.
The unit of diode is volt (V), displaying the positive-
connection voltage-drop value.
When diode testing has been completed, disconnect
the connection between the testing leads and the
circuit under test and remove the test leads
from the input terminals.
