Indicates that a legal program data element was
parsed but could not be executed because the
interpreted value was outside the legal range as
defined by the device (see IEEE 488.2,
11.5.1.1.5.).
An <error/event number> in the range [ -399 , -
300 ] or [ 1 , 32767 ] indicates that the
instrument has detected an error which is not a
command error, a query error, or an execution
error; some device operations did not properly
complete, possibly due to an abnormal
hardware or firmware condition. These codes
are also used for self-test response errors. The
occurrence of any error in this class should
cause the device-specific error bit (bit 3) in the
event status register (IEEE 488.2, section 11.5.1)
to be set. The meaning of positive error codes is
device-dependent and may be enumerated or
bit mapped; the <error message>string for
positive error codes is not defined by SCPI and
available to the device designer.
Note that the string is not optional; if the
designer does not wish to implement a string
for a particular error, the null string should be
sent (for example, 42,""). The occurrence of any
error in this class should cause the device-
specific error bit (bit 3) in the event status
register (IEEE 488.2, section 11.5.1) to be set.
Events that generate device-specific errors shall
not generate command errors, execution errors,
