13.6.3 Density lower-range value
This function allows the operator to define the lower-range value for density measurement in the selected
unit. If density is equal or below this value, the assigned current output will be set to its initial value of
0/4 mA.
After selecting the Density lower-range value function, press
↵ to display the following selection field:
Density 0 % =
XXXXX g/l
The current lower-range value will be displayed. As mentioned in Section 12.4.3.2 Input window/modify a
value, the operator can change the lower-range value for density measurement.
13.6.4 Density upper-range value
This function allows the operator to define the upper-range value for density measurement in the selected
unit. For this density, the assigned current output will be set 20 mA. The applied current of the current
output assigned to the density value is linearly interpolated based on the ratio between the measured
value and the difference between lower- and upper-range value.
After selecting the Density upper-range value function, press
↵ to display the following selection field:
Density 100 % =
XXXXX g/l
The current upper-range value will be displayed. As mentioned in Section 12.4.3.2 Input window/modify a
value, the operator can change the upper-range value for density measurement.
13.6.5 Density limit MIN
The MIN limiting value for density can be evaluated via the status output and thus triggers an external
alarm. This value is entered as an absolute value in the unit defined using the Density unit function.
After selecting the Density limit MIN function, press
↵ to display the following selection field:
Density limit
MIN = 0000.0 g/l
The current MIN limiting value will be displayed. As mentioned in Section 12.4.3.2 Input window/modify a
value, the operator can change MIN limiting value for density measurement.
