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 pro-
gram as the entries describe the cause of an error more precisely than the status regis-
ters. 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.
