I. Note: The above procedure only works because the servo is turned off. In this mode the
setpoint sets the output manually and ignores the motor amperage feedback signal, which
during the catch and weigh test is will be zero. The procedure works because you manu-
ally establish a flow rate with the wheel motor amps and then, without changing the man-
ual output setting, perform a catch and weigh test. In order to select another flow rate it will
be necessary to have the feed spout in place and, with the wheel running, manually set
the output to a new amperage condition.
