ing used by the Model 2000. Example code:

:SYSTem:ERRor? Read Error Queue
Description As error and status messages occur, they are placed into the Error
Queue. This query command is used to read those messages. The Error
Queue is a first-in, first-out (FIFO) register that can hold up to 10 messag-
es. Every time you read the queue, the “oldest” message is read and that
message is then removed from the queue.
If the queue becomes full, the message “350, Queue Overflow” occupies
the last memory location in the register On power-up, the queue is empty.
When the Error Queue is empty, the message “0, No error” is placed in
the Error Queue.
The messages in the queue are preceded by a number. Negative (-) num-
bers are used for SCPI defined messages, and positive (+) numbers are
used for Keithley defined messages. Appendix B lists the messages.
NOTE The :SYSTem:ERRor? query command performs the same
function as the :STATus:QUEue? query command (see STATus
subsystem).
