Zero Rate Tolerance

The Zero Rate Tolerance allows you to set a maximum level that the product control

can detect and not paint an area on the coverage map screen. For example, when

your machine bounces over the field in a zero rate zone, the excess bouncing can

cause the encoder to send out false pulses, which are read as an over application of

the area and painted as purple on the coverage map. By using the Zero Rate toler-

ance feature, you can set up a threshold to ignore the encoder “chatter” caused by

excess bouncing.

Different zero rate tolerances can be set up for different products. On some ma-

chines, the main bin will supply a relatively high volume of product and the zero rate

tolerance can be set relatively high. Other bins that supply micro-nutrients may

apply material at a much lower rate and will need a lower zero rate tolerance setting.

Viper allows you to set differenct levels for each product.

Setting the Zero Rate Tolerance

1. Select Menu, then Setup, Maps, and Cov Map. Press the Next button.

The Zero Rate Tolerance screen displays.

2. Using the screen keyboard, enter the zero rate tolerance setting appropriate

for each product.
