5. Common easy-to -use operations
5.1 Switch on and off
Hard disk switch on/turn on: After connecting power supply, switch on the power button at the bottom
of the scale. After the screen shows one by one the information of edition No., IP address, self-test
countdown “0 、1、2、……8”,the scale enter into sale pattern.
Attention: under self-test situation, please do not press any button and make sure nothing is on
the scale, otherwise it can’t work normally.
Soft disk switch on/off: Please switch on the power button, then press the button [ON/OFF] for 2 seconds.
5.2 Weighing and pricing
There are three methods for weighing and pricing. If the PLU information has been downloaded from
PC or edited in the scale in advance, take the Method 1 and Method 2. If not, take the Method 3.
1. Under the “automatic printing” situation, once the weight is stable system will print label, if the weight
and unit price is not zero showed.
2. When the “AUTO” arrow lights on screen , it means the system is in the state of auto printing .Press the
[AUTO PRN]can switch the state.( You can set whether to auto print or not when starting in the
[SETTING] , the operation is according to the 7.2 system setting .
3. If nothing is on the scale tray or pressing the “zero” button even something on the tray and the light
“zero point” is on, it means the scale is under zero point condition.
4. The following operations, including peeling, pricing with piece, discount and changing price, are based
on automatic printing. If the scale is not under automatic printing condition (automatic printing light is
off), you need to press the button [PRN/ENTER] for label printing.
Method 1: hotkey operation
Example: sale green onion 2kg. Suppose the hotkey is 1 and the unit price is €1.50/kg.
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be
slipped) put 2kg green onion on the scale tray press the hotkey 1. Now, the relevant weight, unit
price and total amount will be shown on the screen and the label will be printed. (PS : In the non-auto
printing status , you need to press the key [PRN/ENTER])
120 hotkeys in total and is changeable and can be printed by control PC.
The above operation is suitable for hotkey 1-60 as for hot button 61-120, the operation is pressing the

8
button [PLU] + the corresponding hotkey.
For easy operation, all the PLU can print the latest illustration. The printing function is set by PC.
Method 2: general operation
Example: sale green onion 2kg. The Fresh Commodity Code is 10 and the unit price is €1.50/kg
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be
slipped), put 2kg goods on the scale press the button [PLU] input the LF code 10 Press
the button [PLU]. Now, the relevant weight’ unit price, total price will be showed on the screen and the
label will be printed.( PS : In the non-auto printing status , you need to press the key [PRN/ENTER])
5.3 Tare operation
The operation is just suitable for the goods need to be packed, e.g. egg, beans etc. There are two
methods used for the following situation:1.package and good separated; 2.Package and goods
non-separated.
Method 1: suitable for package and good separated
Example: sale one box of apple. Suppose the apple’s unit price is €6.0/kg, the hotkey is 05, and the
weight is 2.0kg.
Operation procedure: put a container or package box supposed 1.0kg on the scale press the
button [TARE] put on one box of apple press apple’s hotkey 05 after weighting, take
off the products and then press the button [TARE] again for elimination.
Method 2: suitable for the tare weight known and the package and goods non-separated
Example: sale one box of apple. The unit price is €6.0/kg, tare weight 1.0kg, and the apple and box
weighs 2.0kg in total.
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be
slipped) input the tare weight Press the button [TARE] put on one box of apple press
the hotkey 05 after weighting, press the button [TARE] again for elimination.
5.4 Discount
Discount operation:The discount function can be locked via setting password through PC
background server. Password can be changed through background at any time.
Operation: Discount in proportion
Example: Vegetable is priced at € 8.0 / kg and 5% off, and vegetable's hotkey is 12.
Procedure: Enter discount 95% on the keypad press button [DISCOUNT] put the
vegetables on scale enter the hotkey 12.( PS : In the non-auto printing status , you need to press the
key [PRN/ENTER]).
5.5 Price Changing
5.5.1 Permanent Changing
Method 1:
Example: before changing, apple's unit price is €4.00/kg, after changing, its unit price is €3.00/kg.
And hotkey is 05.
Steps: press the apple's hoykey 05 press button[PRICE] input new price €3.00/kg
press button[PRN/ENTER] weighing and pricing.

9
Method 2:
Example: before changing, apple's unit price is €4.00/kg, after changing, its unit price is €3.00/kg.
fresh commodity code is 15.
Steps: press button[PRICE] input the apple's fresh commodity code 15 press
button[PRN/ENTER] input new price €3.00/kg press button[PRN/ENTER] weighing and
pricing.
5.5.2 Temporary Changing
Method 1:
Example: before changing, cabbage's unit price is €1.40/kg, then temporarily changing to €2.00/kg.
Fresh commodity code is 13.
Steps: put on 2.00kg cabbage input the fresh commodity code 13 press button[PRICE]
input new price €3.00/kg press button[PRN/ENTER]
5.6 Choosing Unit of Weight
Method:
press and hold the button[UNIT] for 1 second (hear beeper) choose new charge unit. e.g.
choose "g" as unit and no operation for 2 seconds means confirm the new unit.

8. Troubleshooting
8.1 Scales crash
Boot up without any response
Reasons:
a. bad contact between the power plug and socket.
b. the power cord is disconnected.
c. Filtering group Fuse is disconnected.
d. Transformer is broken.
e. Motherboard is broken.
Solutions: use millimeter to check them one by one, use method of exclusion to find the solution.
Boot up without any sound, No display, backlight.
Reasons: the spark generated by the power plug impact the program.
Solutions: Replace the Motherboard, reset the number, and download all the files.
Boot up without any sound, display “Update”
Reasons:
a. Program downloads error.
b. Misoperation during the downloading of the program (such as halfway power outage).
Solutions:
a. Reload the correct procedures.Setting IP (default is 192.168.1.87),when update by
Ethernet.And if update by serial port input any number as the scale's ID（the max baud rate
is 115200 ).
b. Ditto.
8.2 Print related issues
Print a blank label, paper orientation is normal.
Reasons:
Setting label type error. Usually the label type computer download is D0, so label type of
label scale printing should be set D0. Or the printed label is blank.
Solutions:
a. adjust the settings in following key order (on the scale).
[SETTING] Enter the system setting Press hotkey[ L ] Enter the select label
type（0：D0；1：D1）Press [PRN/Enter]
b. It’s also available to adjust software on computer. Open label scale , input serial number
of the scale. Change label type to D0 in set function, then carry out function set command.
Print half or a half label, paper orientation is abnormal.
Reasons:
a. Set paper type detection error.

15
b. Printer rear photwas damage.oelectric has slanting direction or is dust.
c. Photoelectric pair of printer rear photoelectric is bad.
Solutions:
a. adjust the settings in following key order on the scale
[SETTING] Enter the system setting Press hotkey[S ] Enter the select label
type（0：label；1：receipt 2: label, without recycle paper roll）Press [PRN/ENTER]
It’s also available to adjust software on computer. Open label scale , set paper type to
“Label” in set function, the pass the setting to error scale.
b. Check whether printer rear photoelectric has slanting direction or is dust.
c. If the problem still can’t be solved, consider changing photoelectric pair. It is better to
handle this step by professional person of our company.
d. Wash the rubber roller.
Wash the rubber roller pictures show:
