The event log records operations and setting changes on the GX/GP in chronological order.
The event log is saved in the measurement data file.
For information about the display, see section 2.5.
Description: section Appendix 1
Recorded Operations
• Operations that affect the measured data, such as record start and message writing, are
recorded. Error messages are also recorded.
• Touch operations and START/STOP key operations, communication operations, remote-
control operations, event-action operations, and automatic GX/GP operations (e.g., error
messages) can be distinguished from each other.
• Operations that do not affect the measured data, such as screen switching and display
configuration changes, are not recorded.
For details, see section Appendix 1.
How the Event Log Is Saved
• The GX/GP can record up to 3000 operations and setting changes (log entries) in its
internal memory. When the number of log entries exceeds 3000, the oldest log entries are
overwritten.
• The log of events that occurred since the previous record stop to the current record stop
is stored in the measurement data file (display or event data file). If the measurement
data file is divided, each time a file is created, the event log up to that point is saved in the
file.
Viewing the Event Log
• You can display the event logs in the internal memory on the GX/GP screen.
The GX/GP can display only the most recent 2000 events from a given event log.
• You can view event logs in measurement data files on the GX/GP screen or Universal
Viewer (standard software).
How to Clear the Event Log
• The event logs in the internal memory are cleared if you execute Initialize all. However,
you cannot execute initialization (clearing event logs) while recording is in progress.
• You cannot clear the event log in a measurement data file.
A user's password may change during operation. The login information is the user name,
user ID (when in use), and the password at the time that the measurement data file was
created. To sign a measurement data file using the standard software (Universal Viewer),
you must log in as a user that is registered in the login information in that file. You cannot
view the login information.
For information about the display, see the Universal Viewer Manual.
