Yield sensor / moisture sensor calibration 17 Yield Monitoring setup
5. Calibrate the Header Height.
6. Calibrate the Temperature.
7. Calibrate the RollOffset.
8.
Calibrate the Yield Sensor Tare.
If the Average Tare Deviation is equivalent to or greater than the thickness of the elevator
paddle, the system may encounter a large amount of noise. “Noise” can be introduced into the
system by any of the following factors:
ll Paddles contacting the Yield Sensor optical lens
l Yield Sensor optical lens obstructed
l Yield Sensor(s) loose
l Elevator chain with excessive slack or paddles flopping up/down
l Tensioning rod contacting yield sensors
l Excessive paddle wear causing large quantities of grain to fall back down the elevator
between the elevator wall and the outside of the paddles
9.
To check the noise percentage of the system, turn the combine separator on at full engine RPM
and then select Yield Monitoring / Diagnostics / Status to see the noise percentage. If this is very high,
check the aspects listed.
Note – If the frequency deviation is high, you may have an inconsistent Elevator RPM and may need to
inspect the performance of your clean grain elevator pulleys, bearings, chain, and so on.
10. Select either method for calibration:
ll Speed method: Uses a consistent speed variable to calibrate for Low, Medium, and High
flows.
l Cut Width method: Uses a consistent cut width variable to calibrate for Low, Medium, and
High flows.
Speed method
1. Conduct a calibration load of 3,000-6,000 lbs. at your normal constant speed.
2.
Repeat this procedure for:
ll One load at 1 mph less than the normal operating speed
l One load at 2 mph less than the normal operating speed
l One load at 1 mph higher than the normal operating speed
This provides a calibration curve for Low, Medium, and High flow variations throughout the
course of harvest.
An example of calibration loads using this method is as follows:
