sunlight and should be kept at flat place.
2.
Do not use the indicator in place of much dust, serious vibration or humidity .
3.
Connection between load cell and indicator shall be reliable and the system should have valid
grounding. Keep them away from high electric and high magnetic fields. Load cell and indicator
shall be kept away from highly corrosive object and inflammable and explosive materials.
▲ ! Do not use in occasion with inflammable gas or stream or system with pressure vessel tank.
▲ ! Do not use in area with high frequency of thunder. Reliable lightning protectors shall be
installed for ensuring personnel security of operators and preventing damage of indicator and
relevant equipment caused by thunder.
▲ ! As load cell and indicator are both static-sensitive equipment, feasible anti-static precautions
must be taken during the process of use. Welding operation or other high electric field
operations are strictly prohibited on weighing platform; in the season of thunder storm,
reliable lightning protection measures must be taken for preventing load cell and indicator
from damage caused by thunder and ensuring personnel security and safe operation of
weighing equipment and relevant equipment.
4.
Do not use strong solvent (e.g. benzene or nitro oil) for cleaning the machine housing.
5.
Do not inject fluid or other conductive particle into the indicator so as to prevent damage of
instrument and electric shock.

External interfaces of the indicator shall be used according to methods defined in the operation
commands. No unauthorized modification to the connection is allowed. In case of any failure,
please unplug the plug and send the indicator to professional manufacturer for maintenance.
Unprofessional weighing apparatus manufacturers are not allowed to fix the indicator by
themselves in command to avoid greater damage. The indicator shall not be opened at random.
Otherwise, we will provide no warranty service.
9.
Batteries are consumables and they are not in warranty scope.
▲! For extending service life of battery, please use it after full charge.
For long time unused, please charge the battery once every two months for 20 hours each time.
▲! Handle with care during transportation and installation. Avoid strong vibration, strike or impact in
command to avoid short circuit inside the batteries and damage of batteries.
10. Within 1 year since the indicator is sold, under normal use conditions, damages not caused by
man-made fault belong to the warranty scope. Please mail the product and warranty card (with
matched ID) to authorized maintenance point or the supplier. The manufacturer provides life-long
