You can map any event that appears with a number in the event queue to any available bit in a
programmable register. The programmable registers and their relationships to the Status Byte
Register are shown in the
Programmable status registers diagram
(on page B-5). The following
example event queue log entries contain actual events that can be mapped to a status model bit.
2731 Trigger Model Initiated "Trigger model #1 has been initiated"
2732 Trigger Model Idle "Trigger model #1 has been idled"
4917 Reading buffer cleared "Reading buffer <buffer name> is 0% filled"
4918 Reading buffer full "Reading buffer <buffer name> is 100% filled"
5080 SMU Source Limit Tripped "Source limiting is active on output"
5081 SMU Source Limit Cleared "Source limiting is no longer necessary and output is
normal"
See
(on page 3-50) for additional information on finding events.
Event numbers
You can decide what events to use to set and clear the bits in the Operation Event Register and
Questionable Event Register. The following table lists the event numbers and descriptions.
This table lists frequently used event numbers. This table does not list all event numbers.

2771
The instrument is nearing an internal temperature where corrective action will be
necessary. The next limit will automatically turn off source outputs or limit other
functionality.
2774
The instrument is experiencing an internal temperature malfunction since it is unable to
supply readings and requires immediate service.
2775
An internal malfunction had cleared itself and the instrument is operating normally.
