Error Messages
Errors are retrieved in first-in-first-out (FIFO) order. The first error
returned is the first error that was stored. Use :SYST:ERR? to read errors.
When user has read all errors from the queue, the error queue becomes
empty and any error query will return +0, “No error”. The MODEL 1105
beeps once each time an error occurs.
Should more than 29 errors have existed, the last error stored in the
queue (the most recent error) is replaced with -350, “Queue overflow”.
No additional errors are saved until you remove errors from the queue.
The error queue is cleared when power is off or after a *CLS (clear status)
command is executed. The *RST (reset) command does not clear the
error queue.
