About the interface cards
The bits of the ESR are as follows:
Bit 0: Operation complete, relates to averaging feature (see below), is set if averaging completed successfully
Bit 1: Not used
Bit : Query error
Bit 3: Device Dependent Error (Hardware defective etc.); errors from -399 to -300 resp. 100...399
Bit 4: Execution Error (current limitation, other limits exceeded); errors from -99 to -00
Bit 5: Command Error; Errors from -199 to -100
Bit 6: Not used
Bit 7 Power On (device was turned on)
Event and status registers can be cleared by using the command *CLS.
Status commands
The Operation Status Register (OPER) (see diagram on previous page) stores the several status (remote, local etc. ) in
register Condition and forwards them to the register Event, as long as they are enabled by Enable. The masks Positive
transition and Negative transition determine if the events are triggered by a rising edge or a falling edge. This can be used
to sense the appearance and/or disappearance of a status.
The same applies for the Questionable Status Register (QUES). The configuration for the OPER, as shown in the diagram,
would cause an event only if the signal „local" changes from low to high. The signal „Function mode", on the other hand,
would cause the event also at a falling edge.
