External function check 1 ... 8: A different device signals "Function check".
Negative/positive
edge
Remark / effect
Calibration 01 to 36
Start single calibration. The calibrations must be assigned in the calibration
pool.
Positive edge
1)
Control of a calibration started via a digital input (Calibration 01 to 36) / start
of the next calibration:
This causes the switch to the next intermediate steps during calibration.
Positive edge
1)
Execution of the next step in the sequence is then time related.
Time 1 after the start of a calibration:
•
There is calibration gas in the device, the calculation is being made, the
signal filter is active.
Time 2:
•
–
–
Time 3 (only with 2-point calibration):
•
There is calibration gas in the device, the calculation is being made, the
signal filter is active.
Time 4:
•
2-point calibration is completed.
1-point calibration is completed (zero gas or span gas calibration)
2-point calibration: Injection of span gas necessary
