APPENDIX A. STANDARD CALIBRATION
A.1 CALIBRATION
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.
Preliminary Steps:
1. Be sure the scale is level and stable during the entire calibration process.
2. If LFT is set to On, calibration is unavailable.
To set LFT to OFF, see Section 1.10, page 1-19.
Note: To use the LFT mode again after turning it off, it is necessary to have the scale
locked and sealed by local Weights and Measures authorities.
3. Allow the scale to warm up for approximately 20 minutes after stabilizing to room
temperature.
4. To abort calibration, press the Exit button anytime during the calibration process.
