3. CALCULATING "SPEED CAL"
Initial SPEED CAL is 598 [152]. Complete Steps 1 thru 6 to refine this number after "INITIAL
CONSOLE PROGRAMMING" has been completed.
1) Set POWER switches to ON, all other switches to OFF.
2) Enter "0" in key labelled:
3) Drive 1 mile [1 kilometer]. To achieve the most accurate calibration, accelerate and decelerate
slowly.
CAUTION: Do not use vehicle odometer to determine distance. Use section lines or
highway markers.
4) Read DISTANCE by depressing key labelled:
DISTANCE should read a value of approximately 5280 [1000]. If it reads between 5260-5300 [990-
1010], the SPEED CAL for the vehicle is 598 [152]. If the DISTANCE display reads any other value,
perform the following calculation:
EXAMPLE: Assume DISTANCE reads 5000 [980].
Corrected SPEED CAL =
Old SPEED CAL x 5280
DISTANCE
ENGLISH UNITS: METRIC UNITS:
= 598 x 5280 = 631.48 = [152] x [1000] = [155]
5000 [980]
5) The number to enter for SPEED CAL is 631 [155].
6) Recheck the new SPEED CAL derived in Step 5 by repeating Steps 2 thru 5.
4. CALCULATING "METER CAL"
LIQUID APPLICATIONS
1) When calculating METER CAL refer to the Flow Meter calibration number which is stamped on the
label attached to the Flow Meter. This number is to be used for gallon per area applications.
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.
GRANULAR APPLICATIONS
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.
