Judge
This bit is used for two purposes:
If Over/Under decision is to be triggered by Judge input, this signal triggers Over/
Under judgment.
If Upper/Lower limit decision is to be triggered by Judge input, this signal triggers
Upper/Lower limit judgment.
1: Judgment ON
0: Judgment OFF
SEQ START
If Sequence mode is selected in Mode selection, ON edge (0 → 1) in this signal
starts a new sequence.
SEQ STOP
While sequence control is underway, ON edge (0 → 1) in this signal will abort the
control sequence resulting in “Sequence error 2” (Error assistance code =3, Error
code =2).
While the system is in the state of sequence error (Error assistance code =3), ON
edge (0 → 1) in this signal resets the sequence error.
Soft LOCK
Soft LOCK enables/disables setting modification for Zero calibration and Span
calibration. If Soft LOCK is set to “1”, any attempt to change current settings for
Zero/Span calibration is inhibited.
Therefore, user must set this bit to “0” before trying to alter calibration settings.
Zero calibration
ON edge (0→1) in this signal initiates Zero calibration. Note, however, this input
is ignored when “Soft LOCK” is set to “1”, “LOCK SW”(DIP switch) is ON, or
a preceding calibration process is still underway.
