From this screen, pressing the Engage key or Enter 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 enter or the system will disengage.
"Cycling" means the sampler assembly is in the process of washing, and lowering for soil sampling.
After a core has been collected and is being held against the electrodes, the status text will change
to the following:
Figure 57
The pH readings on the display show what each electrode is reading at every second. The
sampler will hold the soil against the electrodes and continue to record pH until the readings settle.
The minimum recording time is 7 seconds; the maximum time is determined in the pH settings
menu. The pH values that are recorded are the final values at the end of the logging duration. (last
reading on the display before the "Cycling" status appears). The final pH value is logged along
with the DGPS position where the sample was collected.
If the electrodes take longer than 10 seconds to settle, a warning will appear that indicates the
number of seconds the reading has required to settle. When the maximum log time is reached, the
unit initiates a new sample cycle (refer to Controller setup for adjusting the log time).
