Introduction
Calculate the Meter Cal Value
No calculation of the Meter Cal value is necessary. Enter the product density in pounds/ft
3
[gram/liter] as the
Meter Cal value.
Note:
The Meter Cal value will vary according to the product being applied.
To increase the system accuracy when applying at low rates, use the decimal shift feature
explained in the Decimal Shift Feature section on page 39.
Calculate the Valve Cal Value
The Valve Cal figure is used to control the response time of the control valve motor to the change in the
vehicle’s speed. After operating the system, this number may be refined. The initial recommended control
valve values are:
•
C-SD (standard valve) = 2123
•
C-FC (fast-close valve) = 743
•
C-F (fast valve) = 743
•
C-P (PWM valve) = 43
•
C-PC (PWM close valve) = 43
