6 Hints for special functions
6.1 Moisture evaluation ('WET' - 'MEDIUM' - 'DRY')
Additionally to the measuring value, an individual moisture evaluation will be displayed simultaneously. This
moisture evaluation is only a guidance value, the final evaluation is depending on the application of the
material e.g:
Cement floor pavement ZE, ZFE without additives: Readiness without floor heating at 2,3% with floor heating 1,5%
Anhydrit floor pavement AE, AFE: Readiness without floor heating at 0,5% with floor heating 0,3%
Also firewood may be already usable while instrument still displays ‘wet’!
Corresponding Standards and Instructions must be observed!
The Device can only complement the skill of a tradesman or investigator but cannot replace it!
6.2 Pre-selection of favourite materials ('Sort')
A pre-selection of different materials (up to 8) can be selected from the menu for an effective working with
the device. For example you can set the Menu Sort to 4 and save the desired materials in Sor.1, Sor.2, Sor.3
and Sor.4 if you only measure 4 different materials. Please refer to chapter 4
Only the 4 desired materials can be selected via the buttons up and down, when exiting the menu, a
changing during the measurement can be done comfortably. All materials will be available when setting Sort
to off. Sor.1 to Sor.4 will still be available in the ‘background’, when setting the menu Sort to 4 the limited
selection of the 4 entered materials will be active again. You only want to measure one material: set the
menu Sort to 1 you cannot change to another material, thus a faulty operation is impossible.
6.3 Individually Programmable Characteristic Curves
There are 4 individually programmable characteristic curves integrated.
By using them there can be used other material curves than the already integrated ones.
The programmable curves can be read and programmed by the software GMHKonfig.
As standard they are pre set with the REF-curve. This curve is the base of the determination of user specific
curves.
Each curve is defined by a table with two columns (measuring value REF [%] / display value [%]) with 20
rows.
The name of the curve , which is displayed in lower display, can be set individually. Characters which cannot
be displayed are displayed as a space character.
Each curve contains also limit values for wet and dry evaluation.
As temperature compensation there is a choice between the standard compensation for wood or linear
compensation.
If there should be used no temperature compensation should be used: Choose linear compensation and
enter 0 as compensation factor.
Linear temperature compensation:
MC compensated(T) = MC uncompensated * (1+ compensation factor/10000 * (T-20°C)
MC = moisture content
