Device-Specific Error List
An error 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 the class causes the device-specific error bit (bit 3) in the Event Status Register to be set.
