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 2lb. Suppose the hotkey is 1 and the unit price is ￥1.50/lb.
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be slipped)
put 2lb 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])
224 hotkeys in total and is changeable and can be printed by control PC.
The above operation is suitable for hotkey 1-112; as for hot button 113-224, the operation is pressing the 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 2lb. The Fresh Commodity Code is 10 and the unit price is ￥1.50/lb
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be slipped),
put 2lb 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])
Method 3: suitable for not preset PLU(In the software RLS1000 setting function, select the "Num+ Amt print
label ,print immediately ", then click downloading)
Operation procedure: press the button [ZERO] (if the screen already shows zero, the action can be slipped)
input the unit price, e.g.2.0 Put the goods (1lb supposed) on the scale tray Press the button
[PRN/ENTER].
5.3 Peeling/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/lb, the hotkey is 05, and the weight is
2.0lb.
Operation procedure: put a container or package box supposed 1.0lb 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/lb, tare weight 1.0lb, and the apple and box weighs 2.0lb
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 / lb 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 Rate changing
5.5.1 Permanent changes in the price
There are two methods to change the rates as follows:
Method 1:
Example: Before changing price, apple's price was $4.0 / lb. After price change, apple's price is $3.0 / lb, and
apple’s hotkey is 05.
Procedure: Enter apple hotkey 05 press button [PRICE] type new price $3.0 /lb press button
[PRN/ENTER] start weighting.
Method 2:

10
Example: Before changing price, apple's price was $4.0 / lb. After price change, apple's price is $3.0 / lb, and
fresh code is 15.
Procedure: Press button [PRICE] enter apple code 15 code on the keypad enter new price $3.0 / lb

AMT] key press hotkey 32 in keyboard（Note：if not in auto print mode, should press[PRN/ENTER]key）.
Method 2：
Example 1：Before price change，cabbage price is 1.40/lb，One-time change to 2.00/lb.after change,price return
to 1.40/lb,LFcode is 13.
Steps：put 2.000lb cabbage on scale long press[PRICE]key,till one “DI” sound input LFcode 13 in
keypad input new price 2.00/lb press[PRN/ENTER]key（after that, can press again hotkey 13，see the
price return to 1.40/lb）
Example 2：Sell 0 price PLU with LFcode
The original price of bag jujube is 0, one-time change to 10.00/lb,after sales, price return to 0.
Steps：put 2.000lb on scale input LFcode 32 in keypad press[PLU]key input price 10.00 元
