(chain) synchronously. To do so, one sync input and one sync output must
be assigned per device.
The sync. indicates the start/end of a gas purge. With a 2-point calibration,
two sync sequences determine one single AutoCal sequence step. If such a
2-point calibration does not apply to one device in the chain, assign a
passive calibration for the corresponding steps.
Positive edge

Remark / effect
If the measuring range is not controlled according to the parameter
assignment but by means of a digital input: the measuring rang signaled as
active by the digital input is used ("Measuring range 1 to 4" or autoranging).
Positive/negative
edge
3)
If no digital input is active, the measuring ranges of the parameter
assignment are used accordingly.
If several digital inputs are active, the following prioritization applies:
Positive/negative Measuring range 4 → measuring range 3 → measuring range 2 → measuring
edge range 1 → autoranging
