This is the Data Acquisition screen with GPS status (note: GPS status will blink every second when
engaged to show the OM readings):

readings) The Datalogger will change from OM reflectance readings to GPS during mapping
Figure 89
The display is showing th
e pH values from the pH electrodes, conductivity of the top 1’ (30 cm) and
top 3’ (90 cm) of the soil, and whether you have GPS or DGPS or OM(differentially corrected)
signal. At any time during the mapping process, you can press the 4 key to stop the file. If you
create more than one file from the same field, you can bring the files into a spreadsheet program
and combine them prior to mapping. Note: the #1 key toggles the pH sampler from engaged to
disengaged; the #4 key stops the file.
From this screen, pressing the 1 key as you drive forward will initiate the automatic sampling
process. The software requires movement indicated by the GPS receiver in order to cycle.
Speed must be detected within 5 seconds after pressing 1 or the system will disengage.
If TAP or DI were selected as the wash water type above, the controller will go through a wash
baseline process after engage is pressed for the first time. The status text will change to the
following:
