Bus current offset larger than expected
The word "ONCE" in an event log entry indicates that the event was logged the first time that the event
occurred, but further such events will not be logged until the controller is reset.
The Event Log dialog box has a Save to Text File button that allows you to save a listing of the events to a text
file. It is a good idea to save one of these text files occasionally. The button brings up a "File Save" dialog box.
Select the directory and file name where the text file can be saved, then select OK. The file will be created and
saved in the desired location with a ".txt" extension. A text file saves automatically if a firmware download is
initiated.
Each time after completing an examination of the Event Log, you may want to mark the Event Log with the date.
Since the Event Log is a circular buffer, older events disappear with time. An Event Log date marker will assist
you on your next examination to know which events have occurred since your last examination. The Event Log
data marker is available via the menu choice Actions > Date Into Event Log. Only one date entry is allowed per
day.
