AUTO PID SUBMENU:
Press d 21) Display flashes ENBL or DSBL.

If “Enabled”, the controller can determine, by enabling Start PID, the
optimum values for the three adjustments — Proportional, Reset and
Rate corresponding to P, I, and D. These values may be changed once
the Auto Tuning is complete.
If “Disabled” is selected, the user will manually enter these three
adjustment values. If you want the instrument to do the Auto PID and the
P , PI or PID, first select Auto Disable and enter 0000 for unwanted
parameter. i.e. for PI enter 0000 for the rate.
ANTI INTEGRAL SUBMENU:
Press d 24) Display flashes ENBL or DSBL.
Press b 25) Scroll through the available selections: “Enable” or “Disable”.
Press d 26) Display shows STRD stored message momentarily and then
advances to STRT only, if it was changed, otherwise press a to
advance to STRT to Start Auto Tune PID Submenu (If Auto PID
was Enabled).
If Auto PID was disabled display advances to PRoP
Proportional Band Submenu.
If Anti Integral (Anti Windup) Submenu “Enabled”, this feature
allows the error term outside the proportional band to be
calculated and accumulated for integration. This may be an
important feature in applications where fast response time is
desirable.
