9. Error Messages
Any errors that occur during operation from either the front panel or the remote control interface
will result in error messages. Error messages are displayed in the upper left hand corner of the
LCD display. They are also stored in the error message queue from which they can be queried
using the SYST:ERR? Query. 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, use the error query until the No Error result is received.
