APPENDIX A  STANDARD CALIBRATION 

APPENDIX A.

  

STANDARD CALIBRATION 

A.1 CALIBRATION 

Note

:  This menu is locked out in Legal For Trade applications.  To regain access,  

see Section 1.6. 

Standard calibration should be performed prior to using a scale, and after service.   
See Section 4.2 for Calibration Masses required for each model. 

Note: 

Be careful not to touch the scale or the table while calibration is in progress,  
as it will cause the process to fail. 

 

1.  Press and hold the 

ENTER/Ca

l

 button 

until 

.C.A.L.

 appears. 

 

 .C.a.l. 

 

2. Press 

Yes

.  

CAL

 appears, followed by 

a flashing 

-C-

 while a zero reading is 

stored. 

 

  -C- 

 

3.  The specified calibration weight value 

appears.  Place the weight on the pan.  
The display shows 

-C-

 while the 

reading is stored.  

 

  6000 

 

4.  When calibration is complete, the 

display shows done, and then returns 
to the previous application mode and 
scale is ready for use.  

  Done 

 

NOTE:

  If calibration fails, ensure that the test area is free from drafts and the surface the scale 

rests on is level and free of vibrations.  Then try to calibrate again.  If it continues to fail, there 
may be an internal problem.  To resolve internal problems, follow procedures in Chapter 3.
