AC Line Frequency
Specify the ac line frequency. Since the controller reduces the effect of power line noise on the
analog measurement by integrating the signal over the period of the ac line frequency, the controller
must know the frequency of power in use.
You must switch power to the controller off, then back on, to make a change to this parameter take
effect.
