SCS 450: METER CAL
This is the pulse-vs.-rate calibration number for the flow
meter (
or in system diagrams in this manual).
Obtain this number from the tag affixed to the meter.
Enter it into the SCS 450 and record it on the Calibration
Card.
SCS 450: VALVE CAL
This is the response time calibration number for the
control valve (
or in system diagrams in this
manual).
Obtain this number from the tag affixed to the valve.
Enter it into the SCS 450 and record it on the Calibration
Card.
SCS 450: PRESSURE CAL
Conventional Liquid Fertilizer only:
This DATA MENU sequence sets zero for the pressure
transducer (
in system diagrams in this manual).
Perform this operation only when lines are at zero
pressure.
SCS 450: RATE 1 CAL
This is your primary desired application rate, typically in
gallons per acre.
SCS 450: RATE 2 CAL
This is your secondary desired application rate, typically
in gallons per acre. If you have no alternate rate
preferred, set this to RATE 1 CAL, so that the control
valve won’t slew if you need to switch to MAN mode.
SCS 450: TANK VOL
Optional. If entered, the material consumed (as
measured by the flow meter) is continuously subtracted
from this number, and may be used to signal a low tank
alarm. The number needs to be re-entered at each refill.
SCS 450: TIME
Optional. The SCS 450 (which is always in 24:00 hour
time format) defaults to 00:00 (and resets to that after 10
days of inactivity). You may use this menu to set the
actual time.
