3.3.5 Menu Level Function
The Function menu level is a variable menu whose appearance depends on the
value of the Function parameter. There are linear, square rooted and table func-
tions
Linear function
The input signal is linear before being sent to the display and the output. The
range defined in the menu "Measuring" serves as the measuring range. If the
function LINEAR is active, the other menu items are cancelled.
Parameter name Description Value range
Function Function Value = linear
Square rooted function
Here, the input signal is square rooted before being sent to the display and the
output. This is necessary e.g. for flow measurements with differential pressure.
A free unit can be defined for the display. To do this, the start and end of the
display range and the number of decimal points are defined. It is also possible
to define the unit with 4 characters.

The following section contains descriptions of the parameters MB decimal pl. ,
MB start , MB end and MB unit to describe the table function.
Tables function
This function allows free adjustment of the input variable to the display and out-
put via a table with up to 30 support points. A value pair comprising a measured
value and display value is issued for every support point.
NOTICE
Change of parameter
When switching from TABLE to another function, the table is initialised again
and the existing values are lost.
