4.2.3 Configuration of the input signal 4 . . 20 mA
With input signals 4 . . 20mA, the zero input value in 0 must be
determined by the following ratio:
The following example shows how to adjust the input:

For an input signal of 4 . . 20 mA and an indicating range of 0 . .
600 bar, a zero input value in 0 = -150 bar and a full scale input
in FS = 600 bar results.
To define a negative zero input value please note: It is only possible
to use a maximum of 3 digits for the display:
in 0 = - 25.0 bar or in 0 = -150 bar
The decimal place must be set in M2 accordingly ! (see also 4.2.1.)
Through selection with the + / - keys the menu End will be called up.
Press the SET key to save and end the parameter configuration.
