MAINTENANCE
Warning
To avoid false reading, replace the battery as soon
as the battery indicator appears.
To replace battery
(see figure 12)
n
Disconnect the connection between the testing
leads and the circuit under test, and remove the
testing leads away from the input terminals of
the Meter.
n
Turn the Meter OFF.
n
Remove the screws from the bottom case, and
separate the bottom case from the front case.
n
Remove the battery from the bottom case.
n
Replace the battery with a new Standard 9V
Battery.
n
Rejoin the bottom case and the front case, and
install the screw.

n
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
V
W
terminal
and the black test lead into the
COM
terminal.
2. Set the rotary switch to position
3. Use the SELECT button to select capacity
function
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 50
W
.
The LCD displays the resistance value of a circuit
under test.
Caution :
n
The LCD displays “1” indicating the circuit being
tested is open.
n
When continuity testing has been completed,
disconnect the connection between the testing
leads and the circuit under test.
J. TRANSISTOR TESTING
To test the Transistors, connect the Meter as below :
1. Insert the transistor (NPN or PNP) in the
sockets provided.
2. The measured value is shown on the LCD
Display.
