Quick Start Rules
Shows the Quick Start rule selected for the Calibration. Selecting the correct rules for the
application material can assist with creating an accurate Calibration, particularly if only a
limited number of sample points are available.
The options available are:
•
0-2mm Sand
•
0-4mm Sand
•
4-8mm Gravel
•
8-16mm Stone
•
16-22mm Stone
More information about the Quick Start Rules can be found in Appendix C.
Note this feature is only available for selected sensors
A,B,C Coefficients
Shows the A, B and C coefficients calculated by the best fit algorithm for the entered points.
These values are changed by entering Unscaled and Moisture sample points on the Edit
Calibration Points screen.
For a Moisture sensor, the Material calibration formula is:
Moisture = A x Unscaled
2
+ B x Un C - D
For a Brix sensor, the Material calibration formula is:
𝐵𝐵𝐵𝐵 = 𝐴 − 𝐵 . 𝑒
(
𝐶 . 𝑢𝑢
100000
)
+
𝐷 . 𝑢𝑢
2
1000
The D coefficient
This is the SSD (Saturated Surface Dry) or Water Absorption Value (WAV) property of the
material, available from the material supplier, and should be entered here before any sample
points are entered if this is to be used in the Calibration. Touch to edit.
Edit Points
Accesses the Edit Calibration points Screen.
Cancel
Cancels the edit of the Calibration.
OK
Accepts the edit of the Calibration, and copies the changes to the Hydro-View database.
