General Safety Instructions - LaserLiner MultiWet-Master Compact Plus Mode D'emploi

Completely read through the operating instructions, the „Warranty
and Additional Information" booklet as well as the latest information
!
under the internet link at the end of these instructions. Follow the
instructions they contain. This document must be kept in a safe place
and passed on together with the device.
Function / application
This material moisture measuring device operates in accordance with the re-
sistance and capacitive measuring principle. Material moisture is measured by
2 conductive sensor pads on the underside of the device or by the integrated
measuring probes and calculated in % with internal material-dependent
characteristics. The displayed value shown in % refers to the dry mass.
Example: 1 kg of material containing 500 g of water = 100% relative material
moisture. The device is used to determine the moisture content in wood and
building materials with the aid of the corresponding measuring method. An
additional pop-out sensor on the side of the device determines the ambient
temperature and relative humidity and calculates the resulting dew point
temperature.
The integrated building materials characteristics correspond to the
specified building materials and their designation. Building materials of
the same type but with different designation / composition / strength /
density can however affect the measurement result. Furthermore,
building materials will vary from manufacturer to manufacturer due
!
to the way they are produced. This is why, in the event of different
product compositions or unfamiliar construction materials, a one-off
comparative moisture measurement should be taken using methods
that can be calibrated (e.g. kiln-drying method). If different measured
values occur, they should either be viewed relatively or the index
mode for moisture/drying behaviour should be used.

General safety instructions

– The device must only be used in accordance with its intended purpose
and within the scope of the specifications.
– The measuring tools and accessories are not toys.
Keep out of reach of children.
– Modifications or changes to the device are not permitted, this will
otherwise invalidate the approval and safety specifications.
– Do not expose the device to mechanical stress, extreme temperatures,
moisture or significant vibration.
– Do not use the measuring probe with an external voltage.
– The device must no longer be used if one or more of its functions fail
or the battery charge is weak.
