Screw Recovery Time.
The screw recovery time is the estimated screw recovery time, and is used as the initial value for
validating the recipe. Actual screw recovery times as measured by the presence of the screw recovery signal,
are used to fine-tune the feed rate during operation. The estimated time must be at least ½ of the actual
recovery time. If less than ½, the feeder will interpret the recovery signal as a purge cycle.
Calibration weight.

recovery time. If less than ½, the feeder will interpret the recovery signal as a purge cycle.
Calibration weight.
Calibration weight is determined from the following tables, and is dependant on the disc installed in
the feeder. This weight is the amount of standard density material dispensed by the feeder during one
revolution of the disc. This weight is used as the initial value for recipe validation and feed rate calculation. If
samples are not weighed as described in the next section, this value is used during operation. The weight can
be entered in ounces or grams. The unit of measure is changed by pressing the units button at the middle right
of the screen. Changing the unit of measure will NOT change the value displayed on the screen. The value
initially displayed is the weight which would result in a motor speed of 25%. The valid range of values would
then be ¼ to 5 times this initial value.
