5.7. CHECKING THE STORED UNIT PRICE
5.7.1.
Press [PLU] key twice , the total price window will display *1dc 1* (1 is goods number), the
weight window display weight and the unit price window display the unit price corresponding to
the goods number 1. There are two ways to check:
A. Keep pressing the [PLU] key, press the goods number once, the total price window will
add 1 and the unit price window displays the unit price corresponding to the goods
number each time. When the goods number exceeds 99, it will back to 1 automatically.
B. Keep pressing and hold [PLU] key for 2 seconds to check the stored unit prices quickly. At
this time, the goods number in the total price window will add 1 automatically and the
unit price in the unit price window will change according to the goods number. When in
unit price display, just loose [PLU] key to make a checking.
5.7. 2 .
Press [ENTER] key. the scale will back to normal weighing state and display the unit price need to
check.
5.8.
Voltage saving function
When the scale is type of LED, it has the function of battery saving display to prolong the working
time of the battery, That means if the scale remains zero for 5 seconds and if you don’t operate
the keypad, the weight window will display *0* and the total price window will display.
5.9. OVERLOAD WARNING
When the scale leaves factory, the overload warning value is set at the point of Max. Capacity
plus 9d(d is division value). When the weight of the goods exceeds or is equal to the set value, the
weight window of the scale will display * *and the scale gives out a buzz sound.
5.10. CHECKING THE VOLTAGE OF THE BATTERY
The scale is equipped with 6V/4.5Ah battery. When the voltage is fully charged, it can work about

*1dc 1* (1 is goods number), the weight window display weight
and the unit price window display the unit price corresponding to the
goods number 1. There are two ways to check:
A. Keep pressing the [PLU] key, press the goods number once, the
total price window will add 1 and the unit price window displays the
unit price corresponding to the goods number each time. When the
goods number exceeds 99, it will back to 1 automatically.
B. Keep pressing and hold [PLU] key for 2 seconds to check the
