Units
You can select the unit of measurement in which the product node applies the product.
If you select ‘US’, Viper applies the product in units per acre. If you select ‘Metric’,
Viper applies the product in units per hectare. If you select ‘Turf’, Viper applies the
product in units per 1000 square feet.
Speed Sensor
You can select the type of speed sensor that supplies the speed reading to the Boom/
Speed node. If you select ‘Wheel’, the speed reading is delivered to Viper from a
magnetic type of speed reading system, such as a wheel magnet or drive shaft magnetic
speed system. If you select ‘Radar’, the speed reading is delivered to Viper from a
radar type of speed reading system, such as a GPS unit or other types of non-magnetic
speed reading system.
Speed Cal
You must enter a speed calibration number to calibrate the ground speed. When using
Raven radar as a speed reading system, Raven recommends setting the speed calibra-
tion number at 598. When using a Raven Invicta or Phoenix DGPS receiver as a speed
reading system, Raven recommends setting the speed calibration at 785. If you are
using a different source as your speed reading system, use the Speed Cal Assistant to
determine the correct speed calibration number.
