Calculating Speed
Calibration
To ensure that you are applying the correct amount of product to a field, you must calibrate the speed of the
vehicle to the Viper system. Confirm that the Speed Cal is set to 598 (English units) or 152 (Metric units). The
following instructions show you how to properly calculate the correct speed calibration.
Calculating the Speed Calibration
1.
Press Product Control, then Tally Registers. The Tally Registers screen displays.
2.
Press Reset next to the Distance reading.
3.
Drive the vehicle a distance of one mile (or one kilometer if using metric units).
Note:
Do not use the odometer on the vehicle to determine the distance. Use either section lines or
highway markers to ensure that you have driven the correct distance.
4.
Read the distance value displayed in the Feet field. This value should be 5280 if you drove the vehicle
exactly one mile.
If the value displayed in the Feet field is between 5260 and 5300, the Speed Cal number entered is correct. If
the distance displays a value that is outside the above range, perform the following calculation to determine the
speed calibration:
Where OSC = the Old Speed Cal value, D = the Viper Pro odometer reading, and CSC = the Corrected Speed
Cal.
