Boom Height Calibration (BoomTrac)

Sensor Calibration - Boom Height

The "Boom Height" calibration menu can be entered via the drop down menu in the field "Sensor to Calibrate". It will show the current settings for the items listed below.
Height Sensors at Min. Height [ADC] this ADC value is the average output of the boom height sensors (left + right) at the minimum boom height. This value needs to be calibrated. Automatic enter this menu to calibrate the minimum height value of the boom height sensors. Height Sensors at Max. Height [ADC] this ADC value is the average output of the boom height sensors (left + right) at the maximum boom height. This value needs to be calibrated. Automatic enter this menu to calibrate the maximum height value of the boom height sensors. Sensor Spacing The distance between the sensors in meters.

Calibrate Height Sensors at Minimum Height

On this page, the automatic calibration of ADC value measured by the boom height sensors at the minimum boom height needs to be carried out.

1. Make sure that the boom height sensors are at an equal distance from the center of the boom.
2. Make sure that the angle of the boom height sensors is equal on both sides of the boom.
3. Adjust the boom to a minimum height and make sure that the boom is parallel to the ground (height of both sensors above the ground is equal). This can be checked in "Diagnostics", "Sensor Status 2" where the values for "Boom Height L Outer (mA)" and "Boom Height R Outer (mA)" should be the same. The boom tilt can be adjusted for calibration with switch 20 on the EHC-2 Control Box.
4. Measure the height of the spray nozzles above the ground and enter this value as "Low. Cal. Height (cm)".
5. Press "CAL" button to start the automatic calibration.
6. The actual average sensor value (ADC) can be monitored constantly on the display.
7. After automatic calibration of the minimum boom height, the screen will go back automatically to the "Boom Height Calibration" menu.

Automatic - Boom Low Height Cal.

Calibrate Height Sensors at Maximum Height

On this page, the automatic calibration of ADC value measured by the boom height sensors at the maximum boom height needs to be carried out.

1. Make sure that the boom height sensors are at an equal distance from the center of the boom.
2. Make sure that the angle of the boom height sensors is equal on both sides of the boom.
3. Adjust the boom to a maximum height and make sure that the boom is parallel to the ground (height of both sensors above the ground is equal). This can be checked in "Diagnostics", "Sensor Status 2" where the values for "Boom Height L Outer (mA)" and "Boom Height R Outer (mA)" should be the same. The boom tilt can be adjusted for calibration with switch 20 on the EHC-2 Control Box.
4. Measure the height of the spray nozzles above the ground and enter this value as "High Cal. Height (cm)".
5. Press "CAL" button to start the automatic calibration.
6. The actual average sensor value (ADC) can be monitored constantly on the display.
7. After automatic calibration of the maximum boom height, the screen will go back automatically to the "Boom Height Calibration" menu.

Automatic - Boom High Height Cal.
