5. Function
1>. Calendar, time, temperature display function.
It will display Date,Time and Temperature after power on.
It can set Date and Time by Set Button ‘A’ and ‘+’ button ‘B’ and
‘-’ button ‘C’.Button ‘D’ can check the alarm clock.
2>. Alarm function.
In calendar time mode, press the button D to enter the view
alarm interface.
User can adjust the alarm status and regular time by Set Button
‘A’ and ‘+’ button ‘B’ and ‘-’ button ‘C’.
Buzzer alarm when reach the regular time.Press any button to
end the alarm.
The ON and OFF status display is Chinese.“开”means ON, and
“关”means OFF.
3>. Valuation scale function.
“Calendar mode” and “Electronic scale mode” switching by
button “C”.
The value of unit price “P” can be set by numeric button, and the

Money “M” will be calculated automatically.
The unit price “P” can be accurate to 0.1. At this time, press the
button ‘D’ to switch to the counting scale mode.
4>. Counting scale function
“weighing scale” and “counting scale” switching by button “D”.
1pcs weight D can be set by the digital keyboard, and the system
will automatically calculate the number of N. A single weight of D can
be accurate to 0.1g.
E.g: the national standard weight of one yuan coin is 3.2G. The
weight of the single weight D is set to 3.2G, pan put 10 coins,
electronic scales show weight: 0.032KG, number N=10.
6. Setting method
1>. Setting of calendar and time
Turn on the switch after the power is switched on. Boot mode defaults to
calendar time mode". The screen displays as follows:
In this mode, only four keys of A, B, C and D are effective.
A: setting; press the button ‘A’ in turn, the year, month, day, time, minutes,
seconds of the cursor blinking in turn. It can be adjusted by B and C keys.
B: Add; click and add a value.
C: Reduce; click and reduce the value of one.
D: Check the alarm clock, enter the “alarm clock” interface.
The screen displays as follows:

2>. Setting of alarm clock
In this mode of the interface, press the button A, the alarm switch ON/OFF,
time, minutes, seconds cursor blinking in turn. Then it can be adjusted by buttons
B and C. Press the button D, you can exit the “alarm settings interface” anytime to
return to “calendar time interface”.
The ON and OFF status display is Chinese.“开”means ON, and
“关”means OFF.
3>. Setting of valuation scale
In the display time mode, press the C key, switch to the "valuation scale"
mode.The screen displays as follows:
The first line displays weight, and the unit is KG.
The second line displays unit price “P" and money M”.
In this mode, the 16 buttons are all effective.
Keypad introduction:
1234567890 represents the number, the keyboard can set the value of P, the
value can be accurate to 0.1g.
After setting the unit price, the system will automatically calculate the money
M.
A: clear.
B: clear unit price P
C: switch to “calendar time mode”
D: switch to the “counting scale mode”
4>. Setting of counting scale
Under the “valuation scale mode”, press the button D to switch to the
counting scale mode. The screen displays as follows:

The first line displays weight value, and the unit is KG.
The second line displays D=single item weight, number of N= items.
Keypad introduction:
1234567890 represents the number, the keyboard can set the value of P=,
the value can be accurate to 0.1g.
After setting the unit price, the system will automatically calculate the
Number N
A: clear.
B: clear unit price P
C: switch to “calendar time mode”
D: switch to the “counting scale mode”
5>. System calibration method
After the switch on, the system is stable, put a fixed weight object(Known
weight items) on the scale. If the system is not equal to the fixed weight display,
then press button “#” for 3 seconds. Then the right side of the first line of the
screen shows the “calibration factor". After the calibration factor appears, the
calibration factor can be increased and reduced by the buttons C and D
respectively. By adjusting the "calibration factor", the weight displayed on the
screen is exactly equal to the weight of the object. Finally, press button "#" for 3
seconds, the calibration factor disappears, the calibration is complete.
