Autoranging
2)
Switch measuring range 1 to 4.

Start AutoCal n/AutoVal n in sync.
Starting an AutoCal/AutoVal that is used on several networked devices
(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 pas-
sive calibration for the corresponding steps.
Positive edge

Remark / effect
If the measuring range is not controlled according to the parameter assign-
ment 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
If no digital input is active, the measuring ranges of the parameter assign-
edge

ment are used accordingly.
If several digital inputs are active, the following prioritization applies: Meas-
uring range 4 → measuring range 3 → measuring range 2 → measuring
Positive/negative
range 1 → autoranging.
