5. Operating introduction:

1. Press’SET’ more than three seconds to show ‘SAL’for setting OUT1relay. Press’SET’ again to show ‘SPL’ for setting OUT1deivation Explanation: When ‘SPL’=0, if force value > SAL, OUT1 close; If force value < SAL, OUT release   When ‘SPL’≠0, if force value > SAL+SPL, OUT1 close; If force value < SAL+SPL, OUT1 release                    

2. Press’SET’ to show ‘SAH’for setting OUT1relay. Press’SET’ again to show ‘SPH’ for setting OUT2deivation

3. PressSET to show CIN for entering password. The original password is 00000. If you dont want to change password, press SET for next step. If you want to change password, press CLR to show CON, set your 5 digit password and press SET for next step.

4. Press ‘ SET’ to show ‘SL’ for zero calibration

5. Press’SET ’to show ‘SH’ for load calibration. The loading should be more than half scale. Input corresponding force value.

6. Press’SET’ to show ‘Sd’ for decimal setting. Press ‘∧’ for adjusting decimal location.

7. Press’SET’ to show ‘Id’ for division value.

8. Press’SET’ to show ‘CLFT’ for peel key selection. When ‘CLFT’ is 0, ‘CLR’ can peel. When ‘CLFT’ is 1, ‘CLR’ cann’t peel.

9. Press ‘SET’ to show ‘FIL’ for weight filtering. The value is from 1-9. The value means the speed of value stability. The bigger the value is, the slower the speed stabilize.

10. Press ‘SET’ to show ‘ZERO’, if the time is less than 2 seconds, the value will track to zero.
