This is the Data Acquisition screen with GPS status (note: GPS status will blink every second when

engaged to show the OM readings):

Figure 88

The acquisition screen with OM readings (note: GPS status has changed to show the OM

readings) The Datalogger will change from OM reflectance readings to GPS during mapping

Figure 89

The display is showing the 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:
