Thank for your purchasing of our EXCELL
Weighing Scale. To guide you to use our product
correctly, please read this Manual carefully to
extend the life of machine and to avoid error.
Instruction for Use
1) Please keep the scale in a cool dry place. Do not store it at high temperature.
2) Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the
weigh pan to any strong shock loads.
3) The load placed on the weigh pan must not exceed the maximum weighing 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 conditions. A desiccant sachet may be included to prevent any
moisture build up.
Preparing to Use the Scale
1. Adjust the four levelling feet (if fitted) to set the scale pan level using the spirit level
bubble located at the front of the scale.
2. Avoid operating the scale in direct sunlight or drafts of any kind.
3. 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.
4. 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
5. 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.
6. We suggest to warm up the scale for 15~20 minutes before operation to ensure best
accuracy.
7. Please note when the symbol keeps flashing on the screen, the batteries
need to be replaced.

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 ov er-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.

UNITS:
switching units
Press the UNITS key to switch weight units, the icons or arrows will indicate the
active units as appropriate. The units available are dependent on the exact scale
model.
After power off, the scale will memorize the active units. When the scale is powered
on again, it displays the previously active units.
TARE: tare key
The tare function will not operate during the following conditions:
When the scale powers on, the weight is still below zero after a container is placed
on the weigh pan. Or the tare value is over the full scale capacity.
Tare function
(1) Put a container on the weigh pan and after the weight is stable, press the TARE key
to zero the weight of the container. The screen displays the “Æ0Å” “STABLE” icon.
(2) Put the goods in the container, the screen displays the net weight value of the goods.
(3) Remove the full container; the screen displays the negative weight value of the
container. At this time pressing the TARE key again will cancel the tare and the
scale reverts back to zero. The screen displays the “Æ0Å” “STABLE” icon.
The tare function can be operated continually to the full weighing capacity of the scale.
Continual tare operation is adding or removing tare objects on weigh pan and
pressing the TARE key each time.
NET | GROSS: switch NET or GROSS key
NET/GROSS key is only used in Tare mode.
In the Tare mode, the screen displays the “Net” icon,
In tare mode, when the GROSS icon is on, the weight value on the display is the total
amount of the tare value. When the GROSS icon is off, the weight value on the display
is the net value. press the NET/GROSS key to switch between the “Net value” and the
“Gross value”.
At the Gross status, only OFF and NET/GROSS key s are functional.

2-2 Weight Calibration
In the weighing mode, press the NET/GROSS and ON/ZERO keys at the same time to
enter the External Function setting mode. The LED shows and uses the
NET/GROSS or UNITS key to select to enter the weight calibration mode.
For approved models, setting is disabled.
Weight calibration conditions:
The calibration weight value placed on the weight pan must be over e100, and the
standard deviation of the weight must be within 10%.
The LED displays the calibration
weight value (the maximum capacity
of 1
st
unit) and the unit. The digit on
the right side keeps flashing.
The scale is calculating the internal
value of the zero point. After
stabilization, the LED shows the
calibration weight value.
Press
TARE
key
When the digit on the right
flashes, ensure that the
weigh pan is empty. Then
Press the
TARE
key.
After stabilization
Place the displayed weight
on the weigh pan. Press the
TARE
key. The scale
calculates the full capacity
internal value and after
stabilization, the buzzer
beeps 3 times. Remove the
weight from the weigh pan
and the procedure
is completed.
