Appendix C. Error Messages

Overview

Errors are placed in a queue as they are detected. The queue works on a first in, first out (FIFO) basis. If the queue overflows, the last error in the queue is replaced with error –350, “Queue Overflow”. When all errors have been read from the queue, further error queries return 0, “No error”.

The error queue is cleared when any of the following occur (IEEE 488.2, section 11.4.3.4):

Upon receipt of a *CLS command

Upon reading the last item from the queue

All negative values are reserved by the SCPI standard. All errors unique to the power supply have positive values.
