17 Yield Monitoring setup Yield Monitoring best practices
Yield Monitoring best practices
There are key practices required to use the Yield Monitoring system to best advantage. Read this
before you start the installation and setup procedures.
Installation
The Yield Monitoring System relies on an appropriate installation of the optical sensors. To ensure
the best results:
l Install the optical sensors in the location described in the Installation Guide.
l If the desired location is not achievable, install the optical sensors as high as possible, but no
more than 6 inches (15 cm) below the top spindle of the elevator.
l Installing the sensors lower than 36 inches (90 cm) above the bottom spindle will give
unacceptable results.
l Interference: Ensure that there is no opportunity for interference between the optical sensors
or the retaining brackets and any moving parts on the combine. Be especially aware of chains,
belts, pulleys, and tensioning rods, and keep in mind that their range of motion may be much
greater during operation than when standing still.
l Alignment: Ensure that the optical sensors will not move out of alignment during operation.
l Paddle support bracket: Ensure that the optical sensors will not sense the paddle support
bracket. Refer to the Installation Guide for more information.
Tare calibration
The quality of the Tare Calibration is critical to getting good accuracy, particularly at low flow rates.
To ensure the best results:
l Check the tare daily.
l When performing the tare calibration, run the system at the same speed as you would
normally use during operation.
l While running the system empty, look at the elevator speed. This number must be correct,
typically between 12–20 Hz.
l Run the tare calibration. The tare value represents the measured thickness of the paddles, and
should be approximately correct. It is more important that the number is consistent than that
is exactly right.
l If the measured value is considerably higher than expected, check the entered values for
paddle spacing, and check that the optical sensors are not being obscured by the support
brackets on the paddles.
