Intructions for Use
1. The load placed on the weigh pan must NOT exceed the maximum weighing capacity
of the scale.
2. Protect the scale from high temperatures.
3. Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the
weigh pan to any strong shock loads.
4. Please operate or charge the scale in an open area. Do not squeeze the power cord to
avoid wire on fire.
5. Any suggestion for product is welcomed
Preparing to Use the Scale
1. Locate the scale on a firm level surface free from vibrations for accurate weight
readings.
2. Adjust the four levelling feet (if fitted) to set the scale pan level.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. If possible avoid connecting the scale to ac power outlet sockets which are adjacent to
other appliances to minimise the possibility of interference affecting the performance of
the scale.
5. Remove any weight that might be on the weigh pan before the scale is switched on
and avoid leaving weight on the pan for long periods of time
6. All goods weighed should be placed in the centre of the weigh pan for accurate
weighing. The overall dimensions of the goods being weighed should not exceed the
dimension of the weigh pan.
7. Once the scale has been powered on, it will go through an LCD display test and it is
ready for use when the display shows zero.
8. The scale requires 15~20 minutes warm up before operation to ensure best accuracy
9. Please note when the symbol keeps flashing on the screen, the batteries need to
be recharged.
10. Introduction of Storage Battery
Thank you for purchasing EXCELL Weighing
Indicator, to help use the product properly,
operate smoothly, and extend its life cycle,
please read this manual carefully.

No burning
Caution Corrosion
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.
