Sealed to Prevent Un-authorized Modifications
The scale indicator is sealed by a Category 1 Audit Trail. To access the
audit trail in the normal weighing mode, press and hold the “ON” key. This
will display the current parameter and calibration event count values.
Pressing any key will return the indicator to the weighing mode. The audit
trail system is always active and cannot be altered. Audit trails are stored
in flash memory and do not require batteries to maintain the audit trail
values.
Changing any of the following parameters will change the Calibration event
count value or parameter audit event count value. This will void your
Legal-for-Trade certification unless performed by properly trained
personnel.
