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.

Command Error List

An error in the range [-199, -100] indicates that an IEEE 488.2 syntax error has
been detected by the instrument’s parser. The occurrence of any error in this class
causes the command error bit (bit 5) in the Event Status Register to be set.
