Automatic PID Calculation Feature (Support TK
V1.06/TU V4.18 and above)
2.9.1
Feature Description
As the set value (SV) being changed, the PID parameters would be calculated automatically based on the relation
between two set points after performed auto-tuning twice.
1. After auto-tuning two set points, the SV slope of a
linear function would be calculated based on the
changes of the waveform parameters between two
points.
2. When the SVs being changed, the corresponding PID
parameters would be calculated according to the
calculated slope.

Setup Instructions
Follow the below steps to set up (take channel 1 for example):
Step 1: Set the first set value (SV) to adjust.

After finished auto-tuning, the current set point (Step2 CR) would be changed to the second point (K2) automatically.
Step 4: After both set points being tuned (notice if CR#8 changes back to 0), set the second set value (SV) to adjust
(same as step1).
Step 5: Start auto-tuning (same as step3).
Step 6: When the setting is completed, the auto-calculation feature would be switched to ON automatically. And the PID
parameters would be output differently according to each SV.
