Description of Calibration Values
17
Using the AutoCal menu item will change the value of the Displacement and Full Speed
Displacement Rate menu items. Further refinement can be done by manually changing
the Displacement or Full Speed Displacement Rate menu items.
The AutoCal menu item will not be available if the Loop Mode menu item is set to Manual
or Gravity Feed.
Displacement
The Displacement menu item allows you to set the amount of pulses generated by the
prewet sensor when displacing one gallon of material. This pulses per gallon or pulses
per liter unit may be listed on your prewet sensor’s specification sheet or listed on an
attached tag as a “K-Factor”. The default displacement value is 1500.0 pulses per gallon
or 396.3 pulses per liter. If this value is not known it can be determined using the built in
AutoCal feature. For more information see see AutoCalibration of a Prewet Liquid on
page 37. The Displacement menu item will not be available if the Loop Mode menu item
is set to Open, Manual, or Gravity Feed.
Calculating Prewet Displacement Using SSC5100 Calibration Values
If you know your prewet sensor’s pulses per revolution and your prewet pump’s output
ounces or milliliters per revolution, use the equations below to calculate the appropriate
pulses per gallon or pulses per liter value.

Full Speed Displacement Rate
The Full Speed Displacement Rate menu item allows you to set the maximum amount of
prewet liquid displaced by the prewet pump in a single minute when running at the prewet
pump maximum speed. The default value is 5.0 gallons per minute or 18.9 liters per
minute. If this value is not known it can be determined using the built in AutoCal feature.
For more information see see AutoCalibration of a Prewet Liquid on page 37.
The Full Speed Displacement Rate menu item will not be available if the Loop Mode
menu item is set to Manual or Gravity Feed.
Number Of Set Rates
The Number Of Set Rates menu item changes how many set rates will be available to the
driver during operation. If a set rate is configured with non-default settings and then is
disabled with this menu item, its custom settings will not be cleared. The default value is
6. The # of Set Rates menu item will not be available if the Loop Mode menu item is set
to Manual or Gravity Feed.
Set Rates
Entering the Set Rate submenu presents a list of all the custom set rates available for the
prewet material. The Set Rates menu item will not be available if the Loop Mode menu
item is set to Manual or Gravity Feed.
