This protocol is designed to optimize the loops for disturbance rejection.

There is the possibility for the loop to go unstable at too high gain. Use caution as gain is increased.

1. From the Home Screen, touch the Channel icon for the loop to be tuned
2. Touch Settings > PID Params
3. Choose a Set Point temperature
4. Set Proportional Gain (K_P) to 0
5. Turn off Integral and Differential portions of the loop (T_I & T_D, respectively)
6. While monitoring the error in temperature on rolling graph, slowly increase K_P until the error begins to oscillate
7. Use the and icons, to scale displayed response appropriately
8. Use the icon to pause the graph
9. Note K_P where oscillation begins, K_{P, cr}
10. Use the Cursors enabled by touching the icon to measure the period of oscillation, T_cr
11. Use the following table to set the values of K_P, T_I, and T_D
