Zero Rate Tolerance
Touch the Next button on the Coverage Map Colors screen to display the Zero Rate Tolerance settings for
each product controlled by the Viper Pro.
The Zero Rate Tolerance allows the operator to set a maximum level that the Viper Pro can detect without
recording coverage map information.
For Example:
During product application in rough field areas, excess “bouncing” may cause the encoder to send out false
pulses, which the Viper Pro records as an over application of the area. If these pulses are recorded in a zero
rate zone, the Viper Pro Coverage Map report will display an over application in this area.The Zero Rate
Tolerance feature allows the operator to set a threshold for encoder pulses which can help eliminate “chatter”
reported by the Viper Pro.
