Parameter Description
Lower range Lower mass flow value
value mass flow that is mapped to the
lower nominal range
boundary selected by
Current mode (9306).
Applicable if Process
value (9302) = 0.
Upper range Upper process density
value density value that is mapped to
the upper nominal
range boundary se-
lected by Current mode
(9306). Applicable if
Process value (9302) =
2.
Lower range Lower process density
value density value that is mapped to
the lower nominal
range boundary se-
lected by Current mode
(9306). Applicable if
Process value (9302) =
2.
Upper range Upper medium tem-
value tempera- perature value that is
ture mapped to the upper
nominal range bounda-
ry selected by Current
mode (9306). Applica-
ble if Process value
(9302) = 3.
Lower range Lower medium tem-
value tempera- perature value that is
ture mapped to the lower
nominal range bounda-
ry selected by Current
mode (9306). Applica-
ble if Process value
(9302) = 3.
Upper range Upper standard volume
value standard flow value that is
volume flow mapped to the upper
nominal range bounda-
ry selected by Current
mode (9306). Applica-
ble if Process value
(9302) = 27.
