The function defines the
amount of Rate applied when the input is outside of the Proportional Band.
The ArtE
time and the rtE time are independent and have no effect on each other.
To
increase damping effect and reduce overshoot set the approach rate time for a value
greater than the natural rise time of the process (natural rise time = process value
time to set point).

The Peak feature will remember the highest input the Instrument has had since the

In the following the symbol "#" will be used following letters to refer to either a number "1"
or number "2".
The "1" will relate to SP1 functions, the "2" for SP2. If your control is not
equipped with a second set point, no SP2 functions will appear.
