5. Hold ： Auto hold, with “HOLD” on screen

6. Screen： OCS-26-LCD，5unit, size mm

7. Over load indication：when weight over 1kg than capacity, will indicate ”O-Ld”

8. Low power indicate： the screen shows “Lo” when power lower than 1V(±0.2V)

9. Auto turn off： 60S

10. back light ： yes， 15s no operating after turn on, the back light auto shut off

11. Buzzer ： yes.

12. Function of keys： [ON/OFF]---turn on/ turn off；[UNIT]---unit switch；
[RESET]--- clear.

13. Temperature test： 0~60℃/1℃， 10~40℃±2℃(after calibration) 32~122℉/1
℉(℉=1.8*℃+32）

14. ON/OFF status：turn on shows“HELLO”，turn off shows“bYE”

15. Factory calibration： 1 o’clock， 25kg

16. Data transfer： Bluetooth 4.0 ，UART，wave 9600，8，1（communication
commission），single sending data

17. Data sending： sclae forward basic kg and basic℃ data

18. Data receiving ： not available

19. Distance： wireless bluetooth reach distance at idea condision≥20 m, with wall
≥5 m

20. Working condition： 0~40℃， RH< 90%

21. Power： DC3V （2 pcs no.7 aa battery） current；working current（not
including back light) about 5.9mA，total current（with back light）约 8.8mA；shut off
current 10~20uA（with 3V power supply)
Operation

1. Weighing：put battery in，the scale sounds “di”，screen shows “HELLO”then
shows“0.00kg ”. Hang weight on the hook, indicate weight change. The screen
shows weight changed, when stabled, screen show“HOLD”and sounds“di”. Then
this weight will be sent。 After hold, press [ON/OFF]could unhold，press key
[RESET]could clear the weight and restart weighing. No weight status，press key
[ON/OFF] when shows“bYE”turn off，meanwhile sending turn off code

2. Working status，press key [UNIT] can switch unit，unit could be： KGÆ LBÆ
OZÆ ℉Æ ℃；when choose temperature，will send data（℃）

3. Press[ON/OFF]after set battery, auto choose hold mode. After turn on, press key
[RESET] for 3S until the screen shows“H-oFF”, means Hold function off，press

[RESET]for 3s secondly, the screen shows“H-on”, means Hold function is on

4. Turn off code transferred when turn off，overload shows“O-Ld”and send overload
code，low power shows“Lo”and send power error code。

Calibration

1. Temperature：press [ON/OFF] turn on， when it shows “HELLO” press
[ON/OFF] 4 times and keep last press about 1S→ when it shows“C”（means
temperature calibrating status）， press [ON/OFF] within3s, when screen shows
calibrating times“0x” then shows“35C”into temperature calibrating. Then press
[UNIT] to adjust temperature same as working condition, then press [ON/OFF] to
confirm the temperature and finish temperature calibrating and into weighing
calibrating. Please check the following for weight calibration.

2. Weigh calibration：press [ON/OFF] to turn on，when it shows“HELLO”press
[ON/OFF] 4times fast and keep the last time 1S until it shows“C”. Waiting 3s without
any operation, the scale will into weighing calibration auto. It indicates inner weight
code. Then press [ON/OFF]shows calibration time “0y” then show“2510”（means
25kg/10g）Press [UNIT]could choose Capacity（shows “5010”means 50kg/10g）
Then press [ON/OFF]to confirm into weighting calibration status. When it shows
25kg, put 25kg weight, it will shows “PASS” means calibration finished and back to
weighing status.
Remark：When temperature calibration time over 8 times and weight calibration over
10 times, it shows“iEr”

Wire

1. Power wire：3V supply please pay attention to +/_, wrong power might destroy the
IC.

2. Sensor wire. Red wire V+ or E+, black wire V-or E-, rest 2 wire for S+ & S-.

3. With power supply, into inner weight status checking, pull sensor, if inner weight
increase, the wire in right status, if inner wight decrease, means sensor wire wrong
status, please check S+ and S- status.
