Input
CALSTAT
Enumerated type
READY; ZEROING - WAIT; SPANNING - WAIT,
None
SCAL only; shows present calibration status of associated analyzer.
Bound to the CALSTAT of analyzer 2, this shows analyzer 2's current calibration
status, and is used by the SCAL module as a signal as to what part of its sequence
to do next. For example, it updates AMFNO with a value meaning "Do a zero", and
then monitors CALSTATA(B, C or D) to see if the analyzer has both received the
message and is doing a zero. Once it has done, and CALSTAT is back to normal
again, it goes on to the span step. If the analyzer does not update CALSTAT with
its zeroing message, the SCAL module realizes that the analyzer zero has failed,
and it will abort the calibration cycle at this point.

Bound to the CALSTAT of analyzer 3, this shows analyzer 3's current calibration
status, and is used by the S CAL module as a signal as to what part of its
sequence to do next. For example, it updates AMFNO with a value meaning 'Do a

received the message and is doing a zero. Once it has done, and CALSTAT is
