OVERLAP DISTANCE
The PinPoint™ II system uses 1-meter-squares to record
where spraying has occurred. Any spraying nozzle that
touches one of these squares will cause the system to
consider this as an area that has been sprayed. As the
machine travels along, each nozzle looks to see if the
approaching square has been sprayed or not. If not,
spraying continues. If so, the nozzle shuts off.
Change the Overlap Distance
FIGURE 14: Overlap Distance in the System Setup
menu can be set to skip or overlap. The value is in inches.
Positive numbers cause intentional overlap, and negative
numbers cause intentional skips.
1. Press the SYSTEM SETUP button (1).
2. Use the UP or DOWN arrow buttons (2) to move to
Overlap Distance (3).
3. Press the ENTER button (4).
4. Change the value of the overlap distance.
5. Press the ENTER button to save.
6. Press the ESCAPE button (5) to leave the System
Setup menu.
FLOW METER SIGNAL
When the operation mode is set to N-Ject, the system is
always calculating the flow.
The rate controller is sent a signal for the whole section if
the section is on.
The flow is calculated from the two pressure sensors
(Inlet/Outlet).
Flow meter type must be set as NH3 calculation (default
in N-Ject Mode). The system will not operate correctly if
the type is changed from the default.
FIGURE 14

PinPoint™ II for N-Ject™ NH3 Operator and Maintenance Manual | ©2017 CapstanAg Systems Inc. 11
OPERATION
TM
TURN COMPENSATION
With a standard spray boom, the flow rate is averaged over
the entire boom and that flow rate is based on the speed of
the machine chassis. This results in over application on the
inner radius of the turn and under application on the outer
radius of the turn because the nozzles are traveling at different
speeds than the chassis is during a turn. A tighter turn radius
results in a higher level of misapplication.
With the turn compensation feature engaged, each nozzle will
apply the correct amount of product based on each nozzle’s
speed, calculated using GPS.
The amount of correction available to each nozzle during a
turn compensation turn can be limited by the amount of
available duty cycle during the turn. The ideal target duty cycle
during a tight turn is 55%.
Nozzles determined to be moving backward will turn off. If
only part of the boom is spraying, the flow meter signal is
managed, so the correct rate is applied.
Turn compensation calculates a turn radius from a GPS signal
and adjusts the flow per nozzle to maintain a constant rate.
If you need more information about turn compensation,
contact your CapstanAG field representative or your servicing
dealer.
FIGURE 15: Press the TURN button (1) to turn on and off
the turn compensation feature.
Turn compensation can be turned off for situations like:
