Guide to manual calibration
Manual calibration is recommended for special purposes.
Calibration with uncovered probe only
This is the simplest method and, therefore, is recommended. It is applicable
for higher DK values, which give a higher change of capacitance between an
uncovered and covered probe. The DK value of the solids material is required
to be known, to set the sensitivity range and an increase to the switching-
point.
For the calibration procedure, see
Calibration with uncovered and covered probe
This method is the safest, since it sets the switching-point in the middle
between uncovered and covered probe capacitances. It ensures the
maximum switching distance to both uncovered and covered probe
capacitance, and helps prevent material build-up.
For materials with low DK values, and therefore smaller capacitance
differences for covered and uncovered states, this method is recommended.
