TARE indicator will be on and the container’s weight will be deducted. When it is time to
clear the TARE, take off the container, and press TARE key again.
5. 4 Overload Warning
Please do not add item that is over the maximum capacity.
When reading “—OL—“ and hear beeping sound, remove the item on the platter to avoid
damage to the load cell.
5.5 Unit price setting
To trade with your scale, it is necessary to setting a unit price of the goods, scale then
uses this unit price to determine how much that goods are on the platter.
When scale displaying the weight of the goods placed on the scale, set the unit price
through numeric keys. Set unit price is showed in UNIT PRICE window display, TOTAL
PRICE window display shows the total price of the goods. To cancel the previous unit
price, press Ckey .
5.6 Change unit

6. ACCUMULATOR OPERATION
6. 1 Prepare to accumulate
The scale can be set to accumulate manually by pressing M+ key,
To enable the accumulation function on, see parameters F11RS232 >mode >EP50
Confirm the platter is empty,the current accumulator values is reset to zero, and the
weight reading is stable.only when weight more than 20d
6. 2 Accumulative operation
Put the weighing item on platter，wait for the weight reading to be stable, press the M+
key，the window will show total x，this is current total value.
6. 3 Account operation
To enable the change function on, see parameters F12 change >on
After do accumulate operate, you can press CH key, WEIGHT window will show the

summed price, key in paid money by keyboard, this will show on Unit Price window, and
the Total Price window will show the return value.
Press TARE key to return normal weighing mode and clear memory, if you don’t want

Note: if you haven’t do accumulate operation, you also can use Account function, the
summed price is current total price.
7. UNIT PRICE MEMORY
Scale can store 10 sets unit price.
7. 1 Save the unit price
Hold the PLU key for 3 seconds after you key in the unit price, it will show “save pos” ,
press numeric key 0~9 to select which memory location you want to use. After you do, the
unit price is stored in the scale.
7.2 Load the unit price
If you want to use the unit price stored in the scale, press PLU key, scale will shows
“load pos”, press numeric key 0~9 to select which memory location’s price you want to
use, current unit price will change to the value stored in the memory.
