There are two basic methods for scaling the Process Meter to display engineer-
ing units: scaling by using measured input values or scaling without connecting
a sensor.
•
By setting display value 1 to correspond to input value 1 and display value 2 to
correspond to input value 2, scaling is possible for display on the line that con-
nects these display values together.
•
The teaching function can be used for setting input values 1 and 2.
•
Input value 1 can be greater or less than input value 2 and display value 1 can
be greater or less than display value 2.
•
Input value 1 cannot be the same as input value 2, otherwise input value 2 will
be automatically set to a value obtained by adding 1 to input value 1.
•
Set the scaling value after setting the input range.

For example, if a sensor with 4- to 20-mA output is connected to the K3NX and
the K3NX is set so that it will display “0” for 4-mA input and “999” for 20-mA input,
the following will be the relationship between input and display values.
