ERR?
(Error query) Returns the first error code contained in the Calibrator error queue, then
removes that error code from the queue. Following the error code is an explanation of the
error code, similar to but sometimes containing more specific information than the
EXPLAIN? command. The explanation sent in response to this query can contain
variables specific to a particular error event. See Appendix E for a list of error codes and
error messages.
A zero value is returned when the error queue is empty. To read the entire contents of the
error queue, repeat ERR? until the response 0,"No Error" is returned. For terminal
users, the error queue Returns for ERR? is always 0,"No Error" because error
messages are returned instead of queued.
Response:
Example:
Returns 0,"No Error" when the error queue is empty.
ERR_REF
Chooses the error reference for error calculations.
Parameter:
ERR_REF?
Returns the error reference for error calculations.
Response:
ERR_UNIT
(UUT Error Unit Thresh Hold command) Chooses how UUT error is shown (this iS
nonvolatile).
Parameter:
ERR_UNIT?
(UUT Error Unit Thresh Hold query) Returns presently selected values of ERR_UNIT.
Responses:
*ESE
(Event Status Enable command) Loads a byte into the Event Status Enable (ESE)
register. (See "Event Status Enable Register (ESE)" in Chapter 5)
