IMPORTANT: Ensure that seed meters are properly adjusted and perform and in field population check BEFORE using Population Adjust.

PA is the correction factor the operator calculates and enters into the monitor. Sensor detections are multiplied by the correction factor before display. A PA number of 1.00 displays actual sensor detections. A PA number of 2.00 displays twice the number of actual sensor detections.

A field population check MUST be performed to determine the correct PA correction factor.

Always reset Population Adjust factor back to 1.00 when changing crops, seed varieties, or populations. Calculate new PA factor only if necessary.

Example:

If 160 000 seeds are detected and displayed when 180 000 are planted, divide 180 000 by 160 000 to obtain a PA value (180 000 ÷ 160 000 = 1.13). Enter a PA value of 1.13 into monitor. The monitor multiplies each detected seed by 1.13 and displays an adjusted population of 180 000.

1. Select Menu >> Planter button >> Rates softkey.

2. NOTE: Initial PA setting is always 1.0. PA value other than 1.0 is not needed for soybeans when AccuCount™ seed tube sensors are used. AccuCount™ sensors are identified by a red LED (A) on the outside of sensor housing.

   Select Population Adjust input box.

3. Enter the calculated value. Acceptable range is between 0.1 and 2.5.

4. Perform an in field population check and adjust PA value until monitor displays the same value as actual population.
