9.3 SPEED SETTINGS
9.3.1 Pulses Per Rev
Pulses per Rev (revolution) are the
number of magnets presented to the
implement mounted speed sensor in one
revolution of the shaft being monitored.
For most applications this number will
remain 4. Check your actuator to
determine the correct number of magnets.
9.3.2 Wheel Pulses per 400FT
This is the ground speed calibration number for an implement mounted speed
sensor. The default number is 0.
9.3.3 Speed Calibration
All new systems require a ground speed calibration to ensure accurate area
totals and accurate ground speed readings. To complete the calibration, measure
a course 400 feet long preferably on level ground with a start and finish point.
The drill must be in the down position throughout this procedure.
Note: During the calibration the monitor is counting the number of pulses
produced from the drill mounted sensor. The monitor will display the pulses
counted in 400 feet, which can be greater or less than 400.
Procedure:
1. From the Speed Settings menu
Highlight Speed Calibration and
press SELECT.
