6.2.5 Material
Measurement values (e.g. moisture content equilibrium) are sometimes related
to certain material characteristics. These are taken into account in the
measurement by means of recorded material characteristics. 10 materials with
typical material characteristics are recorded in the factory settings of the
instrument. The material can be reassigned and the characteristic curves
adapted using the PC software (635-2 only).
With an inserted stray field probe 0636 6160, the material characteristics
recorded in the probe are automatically called up. These are predefined and
cannot be changed via the PC software. See instruction manual for probe.
