FUNCTIONS AND FEATURES
1. Zero-setting at any position for switch of incremental measurement
and absolute measurement.
2. mm/in switch at any position.
3. Can keep tracing origin point set.
4. No matter when it's switched on, LCD will all display current slider position
for measurement any time.
5. Adopt absolute origin point, No repeating adjusting zero.
6. Low consumption and long battery life (
≥
2.5 years).
7. No response speed limit and will not cause over-speed error.
To ensure operator safety, use this instrument in conformance with
the specifications, functions and directions given in this User's Manual.
●
Do not disassemble, short-circuit, charge, or heat the battery.
Otherwise it will cause battery explosion and bring harm.
●
If a battery is swallowed, immediately consult a doctor.
●
The outside and inside measuring jaws of this caliper have a sharp edge.

Measurements
IMPORTANT
1. Before using this caliper for the first time, wipe the rust preventive oil from
the caliper with a soft cloth soaked with cleaning oil.
2. Never apply voltage (e.g. engraving with an electric engraver) on any part of
the caliper for fear of damaging the circuit.
3. After use, take corrosion prevention measures.
Corrosion will cause the trouble.

OPERATIONS
Preparation
(1) Dry the surface of the scale sticker (please see IMPORTANT) and clean
all measuring surfaces.
(2) Loosen the clamp screw and move the slider to check if LCD display and
all keys work properly.
Measurement
(1) Press ON/OFF key or move slider to switch on power.
(2) Press in/mm key to select desired unit system.
(3) Move the slider to make two outside measuring faces touch gently and
then observe the display.
a)The display should be 0.00mm at normal mode and then it can take normal
measurement ( because this caliper has been ORIGIN SET before sending).
b)If "……" indicator displays, then hold down ORIGIN switch and
the display is 0.00mm. Now ORIGIN set is finished and then take
normal measurement.
c)If the display are other digits, then press ORIGIN switch long and
the display is 0.00mm. Now ORIGIN set is finished and then take
normal measurement.
(4) Switch of absolute measurement and incremental measurement.
The caliper is at absolute mode under normal use; if it holds down
ZERO/ABS key now, INC indicator will appear at the left corner of
LCD display. And zero-clearing will be done at the same time, then the caliper
will enter into incremental measurement; presses ZERO/ABS key long at
incremental mode, INC indicator will disappear and current absolute value
will show on LCD display. The caliper returns to absolute mode.
Anti-forgery checking (against products from 2012)
Switch-on (by press OFF/ ON), then press in/mm switch and OFF/ ON together
for more than 1min, LCD display showing“ ” this is our products,
otherwise it is counterfeit products.
Battery Installation and Origin (Zero Point) Setting
When " "(low voltage alarm) blinks, it shows flat battery.
Now a battery should be replaced (please always use a CR1632 battery).
Removing an old battery by pushing backward a battery cover and install a new
battery to make sure the positive pole of the battery must face out.
Upon installation of new batteries, the "……"indicator will blink on the display.
Then perform origin setting. Reinstall the batteries if the "……" indicator does
not blink.
Steps:
After installing the batteries, the "_____" indicator will blink on the
display. Move the slider and close the jaws and hold down the ORIGIN switch
for about one second. The "0.00"display appears, indicating origin (zero point)
setting is complete. Reinstall the batteries if the value does not appear.
