Measurement Operation(6)

Note

l In a circuit, a good diode should still produce a forward

voltage drop reading of 0.5V to 0.8; however, the

reverse voltage drop reading can vary depending

on the resistance of other pathways between the

probe tips.

l Connect the test leads to the proper terminals as

said above to avoid error display.

l The LCD will display OL indicating either open circuit

or wrong polarity connection.

l The unit of diode is volt (V), displaying the forward

voltage drop readings.

l To remove the objects being tested from the circuit

when measuring can obtain a more accurate result.

l When diode testing has been completed, disconnect

the connection between the testing leads and the

circuit under test and remove testing leads from the

input terminals.
