3. OPENNING THE UNIT 

A. Removing the Display PCB 

i. Disconnect AC code. 

ii. Put the scale where you can reach both the back and the front of 

it easily. 

iii. Refer to “12. EXPLODED VIEW – UPPER CASE.” 

Pull out the tray and the paper cover. 

iv. On the front side of the upper case are the four screws holding 

the front cover on. Unscrew them and put them in a safe place 

v. Unscrew a bolt that is on the left front side of the main body and 

put it in a safe place. 

vi. Lift the front cover and pull it. Carefully remove the all cables 

including the FPC of the membrane key boards and unscrew the 

screws fastened to the main body with the ground wires. 

vii. The five screws are holding the main PCB on the front cover. 

Remove them and place them in a safe place. Loosing the five 

hooks, pull out the board. 

B. Removing the Main PCB 

i. Follow the steps 1) ~ 5) listed in “1. Removing the Display PCB”. 

ii. Remove the platform, side cover, upper case and rear cover. 

Refer to “12. EXPLODED VIEW – UPPER CASE.” 

iii. Remove the all cables on Main board 

iv. Refer to “13. EXPLODED VIEW – PRINTER MECHANISM.” Unscrew 

the three screws fixing the printer on the main body. Remove the 

sensor support from the main body. 

v. Carefully pull out the printer. 

vi. On the printer, the four screws holding the Main PCB. Unscrew 

them and put them in a safe place.

4. SCALE CALIBRATION 

A. Description 

i. CAL#1 : Shows the span – adusted ADC output. 

ii. CAL#2 : Key test mode 

iii. CAL#3 : Span calibration is carried in the mode 

iv. CAL#4 : Scale Setting mode 

v. CAL#5 : Pure ADC output 

vi. CAL#6 : Printer sensor setting 

vii. CAL#8 : Display test 

viii. CAL#9 : Local gravity Setting 

B. Calibration procedure 

i. Turn the power switch off 

ii. Remove the tray and slide the “CAL” switch toward the other side. 

iii. Put the tray on the platform. 

iv. Turn the power switch on. 

v. CAL#4 Setting 

vi. CAL#3 Span calibration 

vii. CAL#1 Verification & Fine tuning
