B.
Turn the rotary switch to the proper ACV range position;
C.
Connect the red and the black test leads to the tested circuit.
4-4. Resistance measurement
A.
Insert the red test lead into “VΩmA” terminal, and the black one into “COM” terminal;
B.
Turn the rotary switch to the proper resistance range position;
C.
Connect the test leads to two points of the tested resistor.
4-5. Transistor hFE measurement
A.
Switch the rotary to hFE range;
B.
Define the transistor is NPN or PNP type, then insert the emitter, base and collector separately in the relative
hole.
4-6. Diode and Continuity test
A.
Insert the red test lead into “VΩmA” terminal, and the black one into “COM” terminal;
B.
Switch the rotary to Diode range. Forward measurement: LCD will display the approx. value of forward voltage
drop; Backward measurement LCD will display “OL”.
C.
Connect red and black test leads to two points of tested circuir, if the resistance is less than about 400Ω, the
buzzer sounds.
4-7. Non-contact voltage detector
WARNING: This function could be affected by different external interference sources, and then the alarm is activated
by wrong signal. Even if there is no voltage indication, there may be voltage on the circuit. NCV detector is not the
only way to detect if there is voltage. The Measurement result is for reference only.
Turn the rotary function switch to “NCV” position. When the testing circuit is placed above the meter and when the
meter sensor detects voltage, the indicator lights on and the buzzer alarms.
5.
Replace the Battery and the Fuse
When “ ” symbol is displaying, you should replace the battery in time;
If there is no current input when testing the mA current, you should check if the fuse is damaged. if it’s damaged,
please replace the fuse with same type and specification. When replacing the fuse, screw off the fixing screws and
remove the back cover before replacement.
