The CAL 9900 microprocessor based
temperature controller provides precise
control with a minimum of setting up, the
advanced Autotune algorithm tunes all
--------
five control parameters automatically.
The simple setting up procedure below is
normally sufficient. specialised applic
ations may need the comprehensive

AUTOTUNE TYPES AND USES
Two types of Autotune are provided to
ensure optimum control of a wide range
of applications
AUTOTUNE AT - Normal method. tunes
during warm up
AUTOTUNE PT - ( Push-to-Tune) - For
difficult applicolions. tunes at set point
.

AUTOTUNE AT
Start Autotune AT with the load cool. A short
tuning cycle occurs at 75% set point during
warm up. New PIO values ore automatically
entered and the temperature rises to set
point

Used to fine tune difficult applications ot set
point. Useful if the set point or thermal
conditions are substantially changed. During
PT tuning some overshoot will occur. If this
is unacceptable, temporarily reduce set
point. PT tunes the parameters listed above
except DAC. Proportional cycle time is re
calculated but needs manual acceptance

OVERIDING AUTOTUNE VALUES
After AT /PT any Autotuned parameter moy
be changed to an Option from the table.
The original Autotuned value is retained in
memory.
Note Subsequent Autotune AT or PT run
replaces manual selections with new
