Set full-scale range, i.e. the maximum occurring flow. This
affects all functions in which values have to be set as % of
the full-scale range:
Fct. 1.3 Low-flow cutoff Fct. 1.5 Current output
Fct. 1.7 Status output Fct. 2.1 Test Q

The primary constant is used for setting three calibration
values for the primary head.
GKL describes the calibration value at 100mA

Flow direction
↵
Define direction of flow
according to direction shown by arrow on the primary head
Edit
PoS. Flow
↑ neG. Flow
Standard: pos. flow
↵
Set the main direction of flow or
the forward flow in the case of F/R mode:
in direction of arrow = PoS. DFl. (positive flow)
opposite dir. of arrow = neG. DFl. (negative flow)
