When the soil becomes completely saturated, does the CS616/CS625 still provide accurate readings, or does it display “NAN”?

As long as the period value in the saturated soil is less than 42 ms, “NAN” will not be displayed.  Conditions that can cause the period value to be too high include high electrical conductivity, high clay content, and high organic matter content. Under those conditions, it may be possible to get good results by using the PeriodAvg() or P27 instruction with a soil-specific calibration equation.
