Error Messages
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

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.
