CALCULATING "METER CAL"
The Flow Meter calibration number is stamped on the tag attached to each Flow Meter.
Write down this number for future reference when programming the Console computer.
To convert original METER CAL from gallons to desired units of measure (oz, lbs,
or liters per area), see METER CAL CONVERSIONS. Write down this calibration number
for future reference when programming the Console.

CALCULATING "VALVE CAL"
1)
The initial Control Valve calibration number is 2123 for C-Sd, or 743 for C-FC.
After operating the system, you may desire to refine this number. See definitions
below:
For
STANDARD VALVE
(C-Sd):
For
FAST VALVE
(C-FC):
Valve Backlash Digit:
Controls the time of the first correction pulse after
a change in correction direction is detected.
INC to DEC -or- DEC to INC.
Range:
1 to 9
1-Short Pulse
9-Long Pulse
Valve Speed Digit:
Controls response time of Control Valve motor.
CAUTION:
Running the Control Valve too fast will
cause the system to oscillate.
C-Sd Valve
Range:
1 to 9
1-Slow
9-Fast
C-FC Valve
Range:
0 to 9
9-Slow
0-Fast
Brake Point Digit:
Sets the percent away from target rate at which the
Control Valve motor begins braking, so as not to
overshoot the desired rate.
Range:
0 to 9
0 = 5%
1 = 10%
9 = 90%
Dead-Band Digit:
Allowable difference between target and actual applica-
tion rate, where rate correction is not performed.
Range:
1 to 9
1 = 1%
9 = 9%
