4.9.3.2 Audit Trail Seal (USA and Canada only)
For jurisdictions that use the audit trail sealing method, the local weights and
measures official or authorized service agent must record the current configuration
and calibration event counter values at the time of sealing. These values will be
compared to values found during a future inspection.
Note: A change to an event counter value is equivalent to breaking a physical seal.
The audit trail uses two event counters to record changes to configuration and
calibration settings.
The configuration event counter (CFG) will index by 1 under the following
conditions:
- When the LFT setting is changed from ON to OFF.
- When exiting the menu if one or more of the following menu settings
are changed: Stable Range, Auto Zero Tracking (AZT), Filter, IR
Function and Units (kg, g, oz, lb or lb:oz).
The calibration event counter (CAL) will index by 1 when exiting the menu
if a Span Calibration or GEO setting change is made.
Note: The counter only indexes once, even if several settings are changed.
The event counters can be viewed by pressing and holding the MENU button.
While the button is held, the display will show MENU followed by Audit.
Release the button when Audit is displayed to view the audit trail information.
