10. Error and Status Messages
Errors that occur during operation from either the front panel or the remote digital interface will result in
error messages. Error messages are displayed on the front panel display and are also stored in memory
allocated to the error message queue. The error messages in the queue could be read using the SCPI
query command, SYST:ERR?. The error queue has a finite depth; if more error messages are generated
than can be held in the queue, a queue overflow message will be put in the last queue location. To empty
the queue, read out the error queue until the message, No Error, is received. Errors appearing on the front
panel display have a negative number and will generally remain visible until the user moves to another
screen. If multiple error messages are generated in succession, only the last message will be displayed.
Status messages give information on the operational state of the power source. They appear on the front
panel with a positive number.
The table below displays a list of possible error and status messages along with their possible cause and
remedy. Refer to the Sequoia Series Programming Manual, M447353-01 and Tahoe Series Programming
Manual P/N M445374-01 for more details.
