FUNCTIONS
1. With ON/OFF function.
2. With ZERO key for zero-setting at any position for incremental measurement.
3. mm/in key for mm/in conversion at any position.
4. With low voltage check function. It’ll flash at low voltage.
BATTERY REPLACEMENT
OPERATIONS
1. Preparation
(1) Dry the surface of the protective sticker (pls see Notes) and clean the
measuring surfaces.
(2) Loosen the locking screw and move the slider to check if the LCD display
and all the buttons work properly.
2. Measurement
(1) Press ON/OFF to switch on power.
(2) Press mm/ inch to select the desired unit system.
(3) Move the slider to make two outside measuring faces touch gently and press
Zero button to start measuring.
Measurements
Abnormal display(digits flashing or even no display) shows a flat battery and it
should be replaced.
1. Screw off the side screw on the battery cover and take out the button cell,
then put in a new button cell.
2. ABS housing: Push out the battery cover outwards, then remove the battery
to replace a new one.
Note:
the positive pole of the battery must face out. if the battery bought from
market does not work satisfactorily (the power may wear down because of
the long-term storage or the battery’s automatic discharge ect.), please do not
hesitate to contact the supplier.
NOTES
1. The moving speed of the slider can’t excess 1.5m/s or 60inch/s.
2. Being the precision measuring instrument, the electronic digital caliper
should be prevented strike and drop to avoid losing precision during operation.
3. The indicator must be kept clean. Water and other liquids must be prevented
from entering it to avoid damaging its electronic parts.
4. The surface of the caliper can be cleaned with pure alcohol.
Never use acetone.
5. Don’t remove the data output interface cover when the data output is not use.
Never touch it with any metal parts for fear of damaging electronic circuit.
6. No voltage should be applied on any part of the indicator and never carve
it with an electronic pen for fear of damaging the electronic circuit.
7. Take out the battery if the indicator is not in use for a long time.
