DIODE & CONTINUITY TEST
1. Set function switch to
Ω
position.
2. Set range switch to (
) position.
3. Connect the red lead to the anode of the diode to be
measured, and the black lead to the cathode. Read
the forward voltage drop on the display in mV. If the
leads are reversed, the figure “1” will be displayed.
4. Connect the test leads to two points of a circuit.
The buzzer will sound if the resistance is lower
than 50 ohms.
MAINTENANCE
CAUTION.
1. Do not operate the instrument unless the back
cover is place and fastened.
2. Make sure test leads are disconnected from the test
circuit, and range switch is set to OFF before opening
case.
BATTERY REPLACEMENT
1. When batteries become exhausted, or drop below
the operating voltage, a sign will appear on
the left of LCD.
2. Turn off meter and remove test leads from all test
circuits prior to replacing batteries.
3. Remove the screw from the back cover and open
the case. Replace batteries, ensuring proper
polarity is observed.
