instrument status remains unchanged, i.e. other settings are not automatically adapted.
Therefore, control programs should always define an initial instrument status (e.g. using
the *RST command) and then implement the required settings.
Command sequence
As a general rule, send commands and queries in different program messages. Other-
wise, the result of the query may vary depending on which operation is performed first
(see also Preventing Overlapping Execution).
Reacting to malfunctions
The service request is the only possibility for the instrument to become active on its own.
Each controller program should instruct the instrument to initiate a service request in case
of malfunction. The program should react appropriately to the service request.
Error queues
The error queue should be queried after every service request in the controller program
as the entries describe the cause of an error more precisely than the status registers.
Especially in the test phase of a controller program the error queue should be queried
regularly since faulty commands from the controller to the instrument are recorded there
as well.
