Note To improve your view of the waveform, click the Rescale button to
maximize the waveform on the display.
Using a square wave Apply the tuning program with a square wave, and monitor the amplitude of the
settled portion of the error signal. The settled portion of the error signal should be
the same level for both segments, if not, adjust I Gain as required.
Using a ramp
Apply the tuning program with a ramp, and monitor the amplitude of the settled
portion of the error signal. The settled portion of the error signal should be
balanced, if not, adjust I Gain as required.
Upset recovery method Monitor the error signal, then disrupt the system by changing the command by
adjusting the Setpoint control with the Dial. When you do this, the error should
return to zero within 5–10 seconds. If not, increase the reset (I Gain) setting and
repeat the procedure until the error zeros itself within a reasonable time period.
