Legal-for-Trade Certification
Sealed to Prevent Unauthorized Modifications
The scale indicator is sealed by a Category 1 Audit Trail. To access the audit
trail in the normal weighing mode, press [NET/GROSS] and then press [ON]
within three seconds. 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.
