CALCULATING "SPREADER CONSTANT"
1)
For RATE displayed in 1 lb [1 kg] increments:
L
= Length in inches [centimeters], of belt travel per 1 revolution of Encoder
GH
= Gate Height in inches [centimeters]
GW
= Gate Width in inches [centimeters]
English (US) :
Metric (SI):
Spreader Constant = 311,040
Spreader Constant = [18,000,000]
(1 lb)
L x GH x GW
(1 kg)
[L] x [GH] x [GW]
EXAMPLE:
1) L
= 13 inches [33 cm]
2) GH = 7 inches [18 cm]
3) GW = 15 inches [38 cm]
English (US):
Spreader Constant (1 lb)
=
311,040
13 x 7 x 15
=
311,140
= 228
1365
Metric (SI):
Spreader Constant (1 kg)
=
[18,000,000]
[33] x [18] x [38]
=
[18,000,000]
= [797]
[22,572]
NOTE:
Verify Spreader Constant by performing Spreader Constant calibration
procedure in Appendix 7 before field application.
4.
CALCULATING "METER CAL"
Product Density in lbs/cu.ft. [grams/liter] is entered as METER CAL.
NOTE:
To increase the system accuracy when applying at low rates, use the
decimal shift feature as explained in CONSOLE PROGRAMMING.
