Calibration
A number of situations require the scale to be calibrated. They are:
• at initial installation of the scanner/scale
• if the scale cannot be re-zeroed
• if diagnostics indicate a calibration error
• the weigh module has been replaced
Follow the procedures on the following pages to ensure that the scanner/
scale will meet Weights and Measurement requirements.
Certification of the scanner/scale’s weighing apparatus is subject to Fed-
eral, State and Local Weights and Measures statutes and is restricted to
authorized government agencies and/or duly registered agents thereof.
Anytime a scale is calibrated, it should be properly sealed with a lead and
wire or paper seal before being placed into service.
It is your responsibility to check with the appropriate authorities in your
area to ensure compliance with pertinent regulations before removing
any official seals or placing a newly calibrated scanner/scale into ser-
vice.
