Configuration of the table function
With the table function you can realise any output function (display software version 1.1.0
and above). E.g. you can convert the fill height to the fill quantity depending on the tank
shape. You can use up to 32 interpolation points for this purpose.

Table values
Combination of pressure in per cent and corresponding current
value that are used as interpolation points of the table function
Table 14: "Output Table" submenue
You can only edit the table points when the table function is not active. You may need to set
the output function to "linear", for instance (see above) before editing table points.
The table points must be sorted according to ascending pressure. For instance, the 20%
point may not be before the 10% point. Otherwise you cannot activate the table function.
If the first table point is not set at 0%, the start of the table is calculated by means of the first
two interpolation points. The same applies when the last table point is not at 100%.
With the
- and
- buttons, you can scroll through the table points and look at the com-
binations of pressure in per cent and current in mA. With OK, you switch to the edit mode
for the displayed table point. Now enter the first per cent value and then the current value.
When you confirm the current value, you return to the display of the table point you just
edited.

Minimum and maximum current
In the standard setting, the current output is limited at 3.8 and 20.5 mA, meaning a further
drop or rise in the measured variable does not change the current. You can freely select
these current limits for the lower limit between 3.8 and 4 mA and for the upper limit between
20 and 21 mA.
