Yara N-Sensor V3.10
Operation Manual
3.3.1 General
settings
Position longitude and Position latitude:
The approximate geographic longitude and
latitude of the system. These numbers are required for calculation of the current
solar elevation. Normally, values are automatically taken from the GPS receiver.
They only need to be entered if no GPS receiver is connected.
Date (UTC)
and
Time (UTC):
The current time at 0° latitude (Greenwich time). Values
are calculated from local time minus
Time difference to UTC
(see below). To adjust
your local time, use the standard time setting procedure on your computer.
Make
sure that both your local time and the Time difference to UTC are set correctly
as
this is a prerequisite for a good and stable N-Sensor reading!
Time difference to UTC:
Specify the difference (in hours) between your local time and
Greenwich time. Positive values are time zones east of Greenwich; negative val-
ues are west.
Note that you need to change this when you change your clock to
daylight saving time!
Solar elevation:
The solar elevation in degrees above the horizon calculated from
date, time and position.
Task specific presets:
If enabled, the operation mode and the agronomic calibration
parameters can be pre-programmed for individual tasks. See section 8 for further
information.
Directory:
Specifies the drive letter and/or the path to the directory where the N-
Sensor stores log-files and prescription maps. By clicking the
button you can
select from the existing drives and paths. It is recommended that a drive or a path
is selected that belongs to an (external) flash card. This will allow to easily move
files to and from the N-Sensor and will protect the data from unwanted loss if the
computer crashes.
