HIGH position to the BOTTOM of its
travel. Record this time in Table 4,

5. Similarly, record two more time trials
(Trial #2 & #3) for the LEFT boom and
record in Table 4.
6. Repeat Steps 1 through 5 for the
RIGHT, MAIN and ROLL functions.
Your sprayer may not have a roll
feature.
7. Average the three trials recorded for
each boom movement and record this
calculation in the “Average Time” slot in
Table 4.
8. These “Average Times” now represent
how quickly your system can react to
manual control. In Section 4.7, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.
