Using the event log

The event log records events that are reported by the instrument. The event log entries can be one of
the following types:
•
Error: An error occurred. This may indicate that a command was sent incorrectly.
•
Warning: This message indicates that a change occurred that could affect operation.
•
Information: The message is for information only. This is used to indicate status changes or
information that may be helpful to the user. It also includes commands if the Log Command
option is on.
The event log can hold up to 1000 events. When more than 1000 events are in the event log, the
oldest event is removed when a new event is received.

•
The type of event (informational, error, or warning)
