9. Using the check boxes below the graph,
select the Measured velocity and Demand
velocity traces.
Measured velocity
Demand velocity
Figure 52 - Correct value of KVELFF
It may be necessary to make changes to the calculated value of KVELFF. If the trace for
Measured velocity appears above the trace for Demand velocity, reduce the value of KVELFF.
If the trace for Measured velocity appears below the trace for Demand velocity, increase the
value of KVELFF. Repeat the test after each change. When the two traces appear on top of
each other (approximately), the correct value for KVELFF has been found as shown in
Figure 52.
