Mini-AT User Guide
Description
The function of the Event Logger is to record: Date, Time,
UserID#, assigned Sequence Number, Before value and After value
for changes made to instrument item values or other specific user
activity. By default, the Event Logger is 'Unlocked', meaning old
event records begin to be overwritten after 500 event changes. The
Event Log Lock can only be enabled with Mini-AT Link software
when the Event Logger Lock Jumper is installed at JB24, pins
9 & 10.
Once enabled (Locked), the functionality of the Event Logger
conforms to Canadian regulations as specified by Measurement
Canada. Several key requirements include:
• After the Event Logger Lock is selected, the lock is permanent,
i.e. it cannot be changed back to "Unlocked"
• When the number of event records in memory reaches the
maximum of 500 records, the Event Logger information must be
downloaded to a computer before any additional instrument
changes are permitted
• New events are automatically numbered sequentially, starting at
zero
• Only changes that could affect "Billing" are recorded, all other item
changes are not logged.
Select: 0 - Unlocked ---
1 - Locked
Note: Instruments shipped to Canada are factory-set with the Event
Logger LOCKED
