    Copy/pasted from the UC4 quick ref guide, I hope it helps.


    ADJUSTING THE SETPOINT
    The system is in AUTO and can have the
    target average height (setpoint) adjusted.
    • Use the " +/- " switch in AUTO mode to adjust the target height setting.
    • Alternately, adjust the main boom target height by momentarily pressing
    the sprayer’s main lift control switch while in AUTO mode.
    • Each press of the up/down switch increases/decreases the target height
    by one selected unit (cm or inches), respectively
    • The smallest target height setting is called the minimum height override.
    • Default minimum height settings are factory programmed before
    shipping.

    Thanks John, but not what I'm looking to do. I know how to set the height.
    Both outside sensors are reading correct height. Middle sensor is reading 90cm when it's actually 40cm. Have tried to auto retune but stays the same. Want to be able to tell the sensors it's actually reading 40cm

    Hi Rob, sorry about that, I miss understood the question.
    The following is copy/pasted from the UC4 operators manual and refers to the center sensor, or as they put it "main lift sensor"

    B. Adjusting the Sensor Offset
    To compensate for the lack of crop in the “wheel track”, adjust the main lift
    sensor’s height reading offset (zero height) so that the sensor will read higher
    to match the average height of your crop. Perform the following procedure
    using the UC4+ control panel:
    1. Ensure the UC4+ control panel is in MANUAL mode, at the Normal
    Operating Screen.
    2. Navigate to the "More ?" prompt in the SENSOR DISPLAY menu.
    Toggle "AUTO (YES)" switch.
    3. Navigate to the "Main ?" prompt in the SENSOR DISPLAY menu.
    Toggle "AUTO (YES)" switch.
    4. Toggle "SENSOR DISPLAY" switch to display the main lift height
    ("MLht") menu prompt.
    ↓MLht 47↓
    5. Decrease the reading by the difference in height between standing crop
    and trampled crop in the “wheel track”. Adjust this until ALL three
    sections (right, left, main) are level in the field while in AUTO mode.
    The " + " switch will increase the reading, the " – " switch will decrease
    the reading.
    NOTE: This may take some experimentation in field conditions.
    6. To return to the Normal Operating Screen, toggle and hold "SETUP
    (NO)" switch for two seconds.
    NOTE: This is subject to a “trial and error” approach to getting this set
    adequately. The advantage is that AUTOMATIC control will be
    retained for the main section. Depending on the crop, the
    depression caused by the wheel might vary. Keep in mind that
    when turning the implement the “wheel track” will follow a
    different path. If the main roll sensor detects standing crop in
    this situation, the main section will lift momentarily.
    NOTE: Zero height (for the main lift sensor) will need to be reset when
    using SOIL mode operation.
