Overview
User-defined calculations are used to enhance measurement or to adapt the meter to
special process conditions.
A user-defined calculation allows you to create a new process variable by inserting
constants and existing process variables into an equation. The output of the equation is
the new process variable. Depending on your meter, either two or three equations are
available.

Select the user-defined calculation that you want to use.
If you selected User-Defined Calculation 1:
50 = � × 49.98 + �
16 = � × 15.99 + �
50.00 − 16.00 = 34.00
49.98 − 15.99 = 39.99
34 = � × 33.99
� = 1.00029
50.00 = 49.99449 + �
� = 0.00551
