  • Page 13: Calibration

    Calibration Your balance was calibrated at the factory; however, it is nec- essary to re-calibrate upon setup and on a regular basis thereafter. The factory recommendation for calibration is once per week using the maximum permissible weight stan- dard. Reasons for more frequent calibration include 1) moving the balance, 2) organizational procedures, 3) special sam- ples/applications which require documented calibration time/date stamp.
