Bandwidth
The regulator uses discrete steps and the Bandwidth must have a width that allows at least
one tapchange position where the control remains satisfied. To minimize excessive
operations on the regulator, this bandwidth is usually set to include two or three in-band
tap operation positions.
The range is settable from 1.0 to 10.0 volts in 0.1 volt increments, and 2 volts minimum
is recommended. This setting is the total bandwidth.
