Testing a Fuse
1.
Let the function switch to the "ON/FUSE TEST” position.
2.
Hold the fuse size: < 0.157”x 0.4” to be tested in the middle and gently press
it against the fuse tester, make sure that the fuse's two terminals are
touching the two metal contacts of the fuse tester.
3.
If the instrument's built-in buzzer sounds and the LED flashes red, the fuse is
good. If the instrument does not give alarm, the fuse is blown or damaged.
Testing a Bulb
1.
Set the function switch to the "BULB TEST” position.
2.
Hold the bulb to be tested by its tip and gently push the bulb's two
connecting terminals against the two metal contacts of the bulb tester,
make sure that the bulb's two terminals are touching the two metal contacts
of the bulb tester.
3.
If the bulb lights, then it is good. If the bulb does not light, it is damaged.
Removing Bulb from Light String/Set
1.
Move the bulb remover control to stretch out the bulb remover.
2.
Hold the control with thumb and insert the metal plate of the bulb remover
between the bulb husk and the bulb base to make the bulb loose, the pull out
the bulb with your fingers. (Note: Some light strands have what is known as a
"locking" base or clip. These require you to unlock the bulb husk from the base
in order to remove the bulb)
Battery Replacement
If the LED does not flash when the built-in buzzer sounds, the button cells are low and should be replaced immediately. To replace the button cells, set
the function switch to the "
OFF” position first, then press and slide the pocket clip & battery cover out. Replace the exhausted button cells with two new
1.5V LR44 button cells according to the polarity indication. Reinstall the pocket clip & battery cover.
CAUTION:
REFER TO THIS MANUAL BEFORE USING THIS TESTER
DO NOT ATTEMPT TO REPAIR THIS TESTER. IT CONTAINS NO SERVICEABLE PARTS
Operating environment is: 0°C ~ 40°C; relative humidity <85%; indoor use
Notice:
1.
The instrument's AC voltage detection range is: 12Vac ~ 600Vac, at 50/60Hz.Don’t use the instrument to detect an AC voltage below 12Vac or
above 600Vac. Do not use the instrument to detect DC voltage.
2.
If there are several lines, such as 2-phase wires and 3-phase wire, separate them far enough apart from each other and perform voltage
detection on each line.
3.
Always check the instrument on a known AC power source before detection.
4.
Don't use the instrument if it is damaged
5.
Shielded live conductor will not be detected.
6.
Because the instrument's detection limit and sensitivity setting can affect detection, a line (or a device) under test may be live even if the built-in
buzzer does not sound and the LED does not light. To avoid electric shock and personal injury, don't touch any conductor with hand or skin.
7.
To avoid a false alarm, don’t use the instrument in intense electric field environment.
