After washing (or immediately if RO was selected as the wash water type), the unit will continue

cycling and display the following screen:

Figure 91

“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 92

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 by the readings that

indicates the number of seconds the reading has required. When the maximum log time is

reached, a T will appear indicating that the measurement has ‘timed out’, and the unit initiates a

new sample cycle (refer to pH Controller settings for adjusting the log time).

Figure 93

This time warning is to let the operator know that a measurement cycle is requiring excessive time.

While an occasional cycle may exhibit this warning. see the troubleshooting section if this occurs

frequently.
