Note:
• In a circuit, a good diode should still produce a forward voltage
drop reading of 0.5 V to 0.8 V; however, the reverse voltage
drop reading can vary depending on the resistance of other
pathways between the probe tips.
• Connect the test leads to the proper terminals as said above
to avoid error display. The LCD will display "OL" indicating
open-circuit for wrong 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.
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. Press SELECT button to select continuity
measurement mode.
4. Connect the test leads across with the object
being measured.
The buzzer sounds if the resistance of a circuit
under test is less than 100 Ω.

Transistor hFE Measurement
(Figure 7)
Warning
To avoid damages to the Meter or to the
devices under test, do not input any current
over 60V DC or 30V AC.
1. Check that the transistor is PNP or NPN type.
2. Connect the transistor to be measured to the
corresponding jacks.
3. LCD display hFE reference value.
SLEEP MODE
To preserve battery life, the Meter
automatically turns off if you do
not turn the rotary switch or press
any button for around 30 minutes.
The Meter can be activated by
pressing the SELECT button or
turning the rotary switch.
