VERIFICATION OF SPREADER CONSTANT
To verify and refine the Spreader Constant, perform the following procedure (after
completing INITIAL CONSOLE PROGRAMMING):
1) Weigh loaded truck and note weight.
2) Enter the Product Density in lbs/cu.ft. [grams/liter] into key labelled
3) Enter a "0" into the key labelled
4) With the rate switch in the MAN position, unload a portion of the load by
positioning the boom switch to ON.
5) Determine the actual weight unloaded by re-weighing the truck.
6) Compare to the TOTAL VOLUME displayed by the Console.
7) Perform the following calculation to correct the Spreader Constant if desired:
Corrected Spreader Constant = old Spreader Constant x TOTAL VOLUME
EXAMPLE: old Spreader Constant
TOTAL VOLUME amount
actual weight unloaded =
English (US):
Corrected Spreader Constant (1 lb) =
Metric (SI):
Corrected Spreader Constant (1 kg) =
This is the new Spreader Constant. Repeat this procedure until the weight of the
metered material equals the TOTAL VOLUME value.
