During installation of the access tube the top
cap lip is generally flush with the soil surface.
Alternatively the lip can be positioned 5 cm/2
inch above the soil surface. This allows the
Diviner 2000 sample to be taken at 5 cm/2
inch below the soil surface rather than 10
cm/3.9 inch. This can be useful for shallow
rooted crops.
The Diviner 2000 Datum value should match
the alignment of the access tube top cap
Datum plate.
Set Diviner Datum value to:
•
0.0 cm when Access tube top cap is
flush with soil surface.
•
5.0 cm/2 inch when Access tube top cap
is 5 cm/2 inch above soil surface.
