4 Hints For The Special Functions
4.1 Moisture estimation ('WET' - 'MEDIUM' - 'DRY')
Additionally to the measuring value, an individual moisture estimation will be displayed simultaneously. This moisture
estimation is only a guidance value, the final evaluation is depending on the application of the material.
E.g. 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!
4.2 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. (see 2.2 'Sor.X': selectable materials (not available if Sort = off))
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.

----
Sensor broken or device defective return to manufacturer for repair
Value exceeding measuring range Check: Is the value exceeding the measuring
range specified? ->temperature too high!
Err.1
Probe or device defective return to manufacturer for repair
Value below display range
Check: Is the
value below the measuring
range specified? -> temperature too low
!
Err.2
Probe, cable or device defective return to manufacturer for repair
Err.7 system error return to manufacturer for repair
6 Inspection of the accuracy / Adjustment Services
Accuracy can be inspected with the testing adapter GPAD 38 (extra equipment).
To check precision select material characteristic curve “.rEF”, choose as moisture display „%u“ and connect the testing
adapter to the needles. The device must display the printed value for the GMH38xx
If the precision is no more corresponding to the imprint of the GPAD 38, we suggest to send the device to the
manufacturer for a new adjustment.
