In menu item " Scaling" you define the scaling variable and the scal-
ing unit for the level value on the display, e.g. volume in l.
In menu item " Scaling (2)" you define the scaling format on the dis-
play and the scaling of the measured level value for 0 % and 100 %.
In the menu items " Current output" you determine the properties of
the current output.
On instruments with integrated additional current output, the proper-
ties for each current output are adjusted individually. The following
descriptions apply to both current outputs.
In menu item " Current output, variable" you specify which measured
variable is output via the current output.
Depending on the selected measured variable, you assign in the
menu item " Current output, adjustment" the measured values that
4 mA (0 %) and 20 mA (100 %) of the current output refer to.
If the measuring cell temperature is selected as measured variable,
then e.g. 0 °C refers to 4 mA and 100 °C to 20 mA.
The sensor offers the HART modes " Analogue current output" and "
Fix current (4 mA)". In this menu item you determine the HART mode
and enter the address with Multidrop mode.
In the mode " Fixed current output" up to 63 sensors can be operated
on one two-wire cable (Multidrop operation). An address between 0
and 63 must be assigned to each sensor.
