Error/Event Queue

9.2.4
The Asterion DC Power Supply maintains an Error/Event Queue as defined by SCPI.
The queue holds up to 10 error events. It is queried using the SYSTem:ERRor?
command which reads in a First In/First Out (FIFO) manner. The read operation
removes the entry from the queue. The *CLS command will clear all entries from the
queue.
The following error codes are defined in the SCPI 1995.0 specification and are
supported by the Asterion DC Power Supply. Error codes are in the range of [-32768,
32767]. SCPI reserves the negative error codes and 0, while error codes greater than
0 are device specific errors.
