Control Modes and Data Logging
Automatic Control Mode
The application rate is automatically regulated as forward speed varies, to ensure that the actual
application rate constantly matches a preset target rate. The application rate can be manually
nudged up and down from the target rate as required.
Field data ("job summaries") can be logged and are stored in the instrument memory. Up to 75
summaries can be stored. With a GPS receiver and SD data card, as well as creating a job
summary, you can also log the vehicle route and application data to a "dynamic log" file on the
SD card. The job summary data is also appended to this file.
VRT (Variable-rate treatment) Control Mode
This enables the system to be controlled via treatment instructions prepared using Precision
Farming software in conjunction with DGPS position data. To enable fully automatic variable-rate
treatment for Precision Farming applications, the
PS 8000i
requires a suitable DGPS receiver and
a formatted SD data card to implement treatment plans generated in the Precision Farming
software.
A work record file is automatically created on the card to log data confirming the actual treatment.
The job summary data is also appended to this file, which can be viewed in the Precision Farming
software

normal operating functions, and a SETUP screen for calibration functions.
The five sub-menu keys below the screen control the various display functions and settings for
each of the primary screen pages. Text or icons are displayed adjacent to the sub-menu keys to
