Before Using the Scale
In order to use this scale correctly, we suggest you read this manual carefully.
Instructions for Use
1. Please keep the scale in a cool and dry place. Do not store at high temperatures or damp
places.
2. Please keep the scale clean and free from insect infestation.
3. To avoid impact and it is to be used under designated pressure (the weight put on the platter
can not exceed the maximum capacity of the scale).
4. If the scale is not going to be used for some time, please clean and store it in a plastic bag
with desiccants in a dry condition. The scale should be charged every 3 months to prevent
failure of the internal rechargeable battery.
5. Please don’t use different types of dry battery or mix new batteries with used ones.
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 for product is welcome.
Preparing to Use the Scale
1. Avoid operating the scale in direct sunlight or damp environment.
2. 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.
3. 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.
4. 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.
5. 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.
6. The scale requires 15~20 minutes to warm up before operation to ensure the best accuracy.
7. Please note when the symbol keeps flashing on the screen, the scale needs to be
charged.
8. Introduction of Storage Battery
Thank you for choosing EXCELL Weighing Hanging
Scale. To guide you to use our product correctly,
please read this User Manual carefully to extend
the life of machine and to avoid maloperation.

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.

1-3 Keypad Function
ON/ZERO
KEY
When the power is off, press
ON/ZERO
key to switch the indicator on.
When the power is on, press
ON/ZERO
key to return to zero.
Zero Range for non-approval models is ±2% Full Scale.
OFF
KEY
Press the
OFF
key to switch the indicator off.
TARE/PT
KEY: Tare / Pre-tare key
To TARE:
Place the container onto the scale, wait until the weight value is stable, press TARE
/PT
key for zero return and the NET indication is shown on the display.
Place the object onto the container and the display shows the net weight value of the
object.
Remove both object and container, and negative value of the container will show on the
display.
Press TARE
/PT again
to clear “tare value”. The scale returns to zero and NET indication
goes off.
TARE function can remain effective until tare value=full load capacity
Continuous Tare Press TARE
/PT key
for continuous weight increase/decrease on
platter.
Pre-tare cannot be done in tare function. However, if a pre-tare had been preset, and
the tare weight is more than that pre-tare weight, then the Tare can be done.
No Tare can be done under gross weight display mode.
To PRE-TARE:
Press TARE / PT key, use keypad to input pre-tare weight. When the cursor flashes on
the rightmost digit, press TARE / PT key again to complete.
Pre-tare mode, keypad function as followed:
MC => upward key(0~9 digit entry) NET/GROSS => move cursor leftward
UNIT => downward key(0~9 digit entry) TARE/PT => move cursor rightward

NET/GROSS
KEY
In the Tare mode, the screen displays the “
TARE

NET/GROSS
key to switch
between the “Net value” and the “Gross value”.
When the ”GROSS” arrow
shows up, the Gross Weight in the screen = Tare weight +
Net weight, meanwhile, only
NET/GROSS
key is available.
M+
KEY
Sum-up function.
This key is a composite key, while the item total is shown and weight returns to net zero,
press M+ key to erase memory.
When a is new weight added on platter, the sum-up function can be effective. If this
weight had not been removed, no new item can be added.
Display will show the item total for one second, and show the net weight for one second,
then the scale returns to the current weight, and print out the last total.
To clear the Sum-up info, press M+ key to bring up the item total show up, then press
M+ again, to clear the Sum-up value data.
P.s. To execute the clear function, the weight must return to zero.
MC
KEY
Memory clear for accumulation data.
Simple Counting Mode
Use UNIT key to switch unit to Pcs, to enter simple counting mode.
1. Use
NET/GROSS
key to select a sample number from “10 , 20, 50, 100, or 200”. Display
will show 、 、 、 、 in an sequential order by
pressing
NET/GROSS key.
2. Select a sampling number, and put appropriate weight on platter, and press UNIT key.
Display will show “ ”. The scale will enter counting mode after weight is stable,
and display will show the sample number.
Unit weight insufficient ( ) : Sample unit weight < 0.2d (d=division)
Samples insufficient ( ) : total sample < 20d (d=division)
While sampling, if there is insufficient sample or unit weight insufficient indication “”, the
scale is still usable, but there may be slight inaccuracy.
After Power-off, the scale automatically memorizes the sampling number, and it is available
when “Pcs” unit is selected next time.
If the setting is “automatic average unit weight “, if the object on platter > the previous
sampling number more than 5 pcs, and also < less than 100% the previous sampling
number, the scale will execute unit weight calibration automatically.
