This is the pH (mV) span prior to the end point, at which the titrant
speed will be reduced. The speed will increasingly reduce as the end
point is approached.
For titrations where the slope of the curve is high near the end point,
the proportional band setting should be large. If overshooting of the
end point frequently occurs, increase the Proportional band
or decrease the Max. speed setting. A high value for the Pro-
portional band will result in slow titrations.
