Instructions for Use
1. Please keep scale in a cool and dry place. Do not store under high temperatures.
2. Please keep the scale clean and free from insect infestation.
3. Avoid impacting with other items or overloaded with excessively heavy weights (The
load must not exceed the maximum capacity of thescale).
4. If the scale is not going to be used for some time, please clean it and store it in a plastic
bag in dry condition. A desiccant sachet may be included to prevent moisture from
building up.
5. Do not mix different types of dry battery or mix used dry batteries with new dry batteries.
6. Please operate or charge the scale in an open area. Do not squeeze the power cord to
avoid wire on fire.
7. Operating temperature: -10℃~ + 40℃
8. Any suggestion is warmly welcome.
Preparing to Use the Scale
1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.
Adjust the four leveling feet to centre the leveling bubble on the scale.
2. Avoid hot sunshine directly on the scale or near the exhaust port ofventilating system.
3. Please use a separate power source plug, to avoid the disturbance of other electric
appliance.
4. There should be no weight on the scale when power is turned on.
5. Commodity should be placed at the centre of platter when being weighed, and its size
should not exceed the dimension of the platter.
6. Please warm the scale 15 ~ 20 minutes before using.
7. Please note that when symbol appears on the screen, the scale needs to be
charged.
8. Introduction of Storage Battery:
Thank for your purchasing of our EXCELL Weighing
Scale. To guide you to use our product correctly, please
read this User Manual carefully to extend the life of
machine and to avoid error.

Due to the storage battery adopt the advanced free-maintaining technique, customers need
not to replenish electrolyte.
The scale should be recharged every 3 months to prevent failure of the internal
rechargeable battery.
1. The battery should be charged for 8~10 hours.
2. The temperature of battery should below 45℃.
Maintaining
1. Please do not discharge with over-current when using the battery. Please charge the
battery after discharging current.
2. Please take down the battery when the scale is not used for a long time or break the
connection of cathode.
3. Do not short the battery terminals to check whether there is current. Please check
whether the connection point is firm to guarantee good connection.
4. The battery should be replaced by specialized person. No reverse-battery or the
product will be damaged.
a) Anode of battery should be connected with Anode of product battery（usually red
cable）
b) Cathode of battery should be connected with Cathode of product battery (usually
brown cable or black cable)
c) See the picture following
Safety warnings
1. The electrolyte of battery is caustic which causes metal, cotton, etc to corrode.
2. The hydrogen will be resolved when using or charging the battery and it will cause
explosion when approaches fire.
Brown cable(or black cable)
connected with Anode of
battery

Chapter 1 Introduction
1-1 Production Introduction
1. High performance A/D converter
2. According to different resolution to do linearity calibration
¾Ordinary resolution models (below 10000)
Do specification calibration first then do weight calibration
¾High resolution models (10000~30000)
Do linearity calibration first→specification calibration →weight calibration at last
3. One group of RS232 (option)
4.4 HOLD functions (contain animal scale HOLD function)
5. LCD display
6. Adapter and rechargeable battery
7. Blackout automatically in order to keep the system stable
(When battery voltage is lower than system voltage, the system will cut the power off
automatically to ensure its stable and accuracy.)
