Adaptive Tuning

6-16 Clean Room Oven
Adaptive tuning continuously evaluates tuning parameters. Adaptive tuning
automatically installs new values if better accuracy is possible. Adaptive
tuning should be used when the characteristics of a process change due to
load or setpoint changes or, in a process that can not handle the oscillation
caused by a one-shot tune.
To tune your oven using adaptive tuning:
1. Load your furnace with a load characteristic of those you intend to
heat in it.
2. Press the PAGE button until display reads, "Atun LiSt."
3. Press the SCROLL button until "drA OFF" is displayed.
4. Press the UP or DOWN button to select "on."
5. Press the SCROLL button until "drA.t" is displayed.
6. Press the UP or DOWN button until the desired trigger value is
achieved.
