4.7 Tuning Parameters Set Up Group
Introduction
Tuning consists of establishing the appropriate values for the tuning constants you are using so that your
recorder responds correctly to changes in process variable and setpoint. You can start with predetermined
values but you will have to watch the system to see how to modify them. There are two Tuning groups
available.
Tuning group prompts
Table 4-6 lists all the function prompts in the Tuning 1 and Tuning 2 setup group and their definitions.
