Execution Error Messages
[−299 to −200]
An error number in the range [−299 to −200] indicates that an error has
been detected during instrument execution. The occurrence of any error
in this class will cause the execution error bit (bit 4) in the event status
register to be set. If this bit is set, one of the following events has
occurred:
• A <program data> element following a header was evaluated by the
device as outside of its legal input range or as otherwise inconsistent
with the device capabilities.
• A valid program command could not be properly executed due to
some device condition.
Execution errors will be reported by the device after rounding and
expression evaluation operations have been completed. Rounding a
numeric data element, for example, will not be reported as an execution
error.
