- Be sure to check the status after every command. The Standard Event,
OPERation and QUEStionable Status registers provide a general idea of what
went wrong, and the status message on the Error/Event Queue (retrieved by
SYSTem:ERRor?) provides a detailed diagnostic. See Chapter 8-Error Codes
for the exact interpretation of these error messages. It may be convenient to
set up the Enable bits to generate a ReQuest for Service (RQS) when an error
is encountered.
