 The valve will turn on at the indicated setting for a short amount if time, dependent on the DZ
setting. The LCD screen will show the actual change in height.
 Ensure the boom moves in the clockwise direction (left boom up, right boom down).
If the boom moves in the opposite direction, check your wiring and/or hydraulics for
an installation error.
 The change in height reading is live as long as you hold the "MANUAL" switch. Wait until the
height reading has settled to a stable value and record this reading.
 Some sprayers may exhibit unwanted movement in the boom due to mechanical
play. This may cause some of the tests to show no movement at all if the mechanics
of the boom are loose. It is recommended you take at least five readings to ensure
your tests are accurate.
 Average your five readings. The acceptable average change in height should be from 13 to 38
mm (0.5 to 1.5 inches) (ideal would be 25 mm (1 inch) exactly).
 If the average is less, increase the DZ setting with the " +/- " switch. If the average is more,
decrease the DZ setting with the " +/- " switch.
 Repeat the Manual Dead Zone Test until the average falls into the acceptable range.
 When you are satisfied with the DeadZone roll clockwise test (" DZ "), repeat this test for the
roll counter clockwise (" DZ ").
6. If this boom is a 32, 33, or 36m TWIN FORCE (HAZ), navigate to the ROLL KP screens and change
both the clockwise and the counter-clockwise ROLL KP values to 2.
