Securing the Calibration Switch

Most countries require that the Calibration Switch and Scale Board be secured before a unit can be put into operation.

Some states and jurisdictions permit the use of the Audit Trail in place of the physical seals. Check with your local inspector or governmental agency about using the Audit Trail.

This procedure begins with the unit already disassembled with Tower Cabinet in place and access to the Calibration Switch.
