The "Wheel" calibration menu can be entered via the drop down menu in the field "Sensor to Calibrate". Two options are available (Manual and Automatic) for the item listed. Actual Wheel Used select between two pulse values for the wheel sensor, indicated as "Narrow Tire" and "Wide Tire" from the drop down list in this field. For each selection, there is a corresponding wheel calibration pulse number. This allows for a quick selection of another set of wheels. Manual - Wheel Pulses [pulses/100m] the number of wheel pulses generated by the wheel sensor per 100 m can be entered here with the numeric keys (the value can have one decimal place, giving a resolution of 1 pulse per 100m). The pulse number depends on the type of tire (circumference), the number of pulses per tire revolution (wheel sensor integrated in drum brake on 800-series trailed sprayer) and the soil conditions. The pulse number must be calibrated in the field . Find in the table the factory settings of row crop tires "Narrow" and flotation tires "Wide" as reference

Automatic Wheel Calibration Automatic calibration of the wheel sensor can be done in this menu. It has three steps. The calibration has to be done as follows: Step 1. 1. Fill the solution tank of the sprayer half full with liquid. 2. Measure and mark a distance of exactly 100 meters in a field which is representative for the average fields to spray. 3. Drive with the sprayer to the start point of the 100 m course. 4. Press "CAL" button when the front tire crosses the start line (Calibration has begun). Step 2. 1. Drive the 100 m in a straight line at a normal speed. When calibration is ON, each pulse received from the wheel sensor is counted and shown on screen. 2. There should be at least 100 pulses per 100 m otherwise a calibration error will be given. 3. At the end of the 100 m course, press "CAL" button again. Calibration will go OFF and the new pulse value will be determined. There should be at least 100 pulses per 100 m otherwise a calibration error will be given. Step 3. Shows the calibration is complete and the resultant counted pulses.
