4 Handling
4.1 Start of operation
Switch the device on with the on/off key. After segment test the device is ready for measuring.
4.2 Selection of the characteristic curve
Selection of characteristic curve: by pressing
the characteristic curve can be selected.
The use of inappropriate characteristics can cause faulty measurements!
Selectable material characteristics: (via “Sort”-function preselected, please refer to operating manual GMH 38xx)
4.3 Temperature Measurement
The Temperature value will be displayed temporarily when key is pressed.
Let the Probe adjust to the material for at least 20 seconds to achieve good measuring precision
5 Principles of the measurements
5.1 Moisture rating ( WET - MEDIUM - DRY )
In addition to the measuring value there is a moisture rating via bar graph.
This rating can only be a first approximate value, because factors like the application
field of the measured material have to be taken into account for the final rating.
Experience and knowledge can only be supported by this instrument, not replaced!
5.2 Moisture u and water content w
Either moisture u or water content w is needed according to the application. The BaleCheck 100 is
supposed to be used the unit moisture u (relating to oven-dry mass). In some cases, like rating of
combustibles, the water content w may be more suitable.
The instrument can be configured to both of the values, please refer to GMH 38xx manual.
Moisture u (relating to oven-dry mass) – recommended setting
The unit is %u (also common: % atro, weight percent)
Example: 1 kg wet hay that contains 500 g water has a moisture u of 100%
Water content w (= moisture relating to wet total mass, please refer to operating manual GMH 38xx)
5.3 Temperature compensation
The temperature compensation is important for a reliable moisture-measuring.
There for the device features a temperature measuring at the Tip of the injection probe.
According to the selected material characteristic curve the device will use the associated tempera-
ture compensation.

Characteristic curve
By means of additional equipment (not within scope of
supply) wood and building materials of many kinds can
be measured – therefore the user has to add the refer-
ring characteristic curves to the Sort- Preselection, or
deactivate it complete.
