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 the scale).
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. 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 of
ventilating 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
recharged.
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.

2-2-3 Totalizing
1. Weight Totalizing
Place goods on the platter, after stable and press key to save the weight value.
Then the display shows the total number of additions and the totalized weight value.
And the (M+) indication “” will flash on the display. The indicator will recover to show
the weight value of the goods on the platter after 3 seconds and the (M+) indication “”
is on.
The indicator allows the next totalizing operation, even when the weight value does not
return back to zero. The
key is functional, when the weight value changes by more
than 10d. The indicator will save the totalized weight value after the weight is stable.
The indicator can totalize positive or negative weight but can’t do both at the same time.
The totalized weight store must be reset to zero before it is possible to select positive or
negative totalizing mode.
The totalizing function can be used up to a maximum of 9999 times before it must be
reset. The totalizing display is limited to 6 digits maximum.
When totalizing, RS-232 will also output. ( Refer to F5 setting)
2. Clear Totalized Weight Values
♦ Press
then key to clear all totalized weight values.
♦ When changing between weighing and counting mode, or selecting weighing unit, the
indicator will automatically clear all the totalized weight values.
♦ The indicators will automatically clear all the totalized weight values after turning on.
3. Recall Totalized Weight Values
Press key to display the total number of additions and the totalized weight value.
And the (M+) indication “” will flash on the display. The indicator will return to the
weighing mode after 3 seconds.

The indicators with two weighing ranges can NOT pre-set the tare value larger than the first
weighing range. For example: a 30 kg indicator is set by two weighing ranges. The first range
is 0 to 15 kg, and the second range is 15 to 30 kg. The pre-set tare value can not be larger
than 15 kg.

, , , accordingly.
o Select sample quantity and then place samples on the platter, and then press key,
the display shows “ ”.
After stable, the scale enters into counting mode and the display shows sample quantity.
♦ Sample Too Small ( ) ⇒ Sample is less than 20 divisions.
♦ Unit Weight Too Small ( ) ⇒ Unit weight is less than 0.2 division.
(0.1 d for Brazil regulation)
When sampling, the above two symbols indications are on. Under such conditions, the
scale can still work, but may result in lower count precision.
When using 2-segment weighing mode, the above two symbol indications change to
Range 2 and Range 1 and the two symbol indications are off.
2-3-2 Check Weighing
Refer to the operation of check weighing in weighing function.
