Materialkennlinien

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 instrument detects and evaluates the material moisture content of wood and building materials by way of electric resistance measurement. The displayed value is material moisture in % with respect to dry mass. Example: 100% material moisture for 1 kg of wet wood = 500 g water.

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.
• The structure of the device must not be modified in any way.
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The device must no longer be used if one or more of its functions fail or the battery charge is weak.
• Do not use the measuring probe with an external voltage.
• Please ensure compliance with the safety regulations set out by local and national authorities with regard to the correct and proper use of the device.

Safety instructions

Dealing with electromagnetic radiation

• The measuring device complies with electromagnetic compatibility regulations and limit values in accordance with EMC-Directive 2014/30/EU.
• Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.
• The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.

Measurement procedure notice

Be sure neither supply lines (electric lines, water pipes, etc) nor a metal subsurface is present at the location to be measured. Insert the electrodes as far into the material as possible but never use excessive or sudden impact force as this could damage the unit. Always pull the unit out of the material with left/right twisting motion. Perform several comparative measurements at different locations to minimise measurement error. The sharply pointed electrodes present an injury hazard. Always put the safety cap on the unit when it is not in use or being transported.

6 Wood

The location to be measured should be untreated, free of knots, dirt and resin. Measurements should not be made on the end faces of wood because these areas dry particularly quickly such that they produce incorrect measurement results.

Perform multiple comparative measurements. Wait until the

% symbol stops blinking and remains constantly lighted. Only then are measurement values stable.

7 Mineral building materials

Be aware that walls (or surfaces) with differing material structures, or even variations in material composition, can cause measurement results to be falsified. Perform multiple comparative measurements. Wait until the % symbol stops blinking and remains constantly lighted. Only then are measurement values stable.

Material characteristics

The material characteristics available for selection in the measuring device are listed in the tables below. The different types of wood are divided into Groups A and B. Please set the measuring device for the respective group in which the type of wood to be measured is found (see Step 4). A similar setting must also be made for measurements performed on building materials (see Step 4). Building materials are classified from 1 to 3.

9 Table of building materials

Integrated building materials / measuring range

1 Cement screed without additive / 1.0 ... 4.5%

2 Gypsum plaster / 0.1 ... 38.2%

3 Cellular concrete (Hebel) / 2,2 ... 99%

Tip: Moisture measuring devices that operate in accordance with the resistance method can be used to compare measuring points – in this case the numerical value only serves as an index value. Take a sample measurement in a dry area of the same material, note down the value and compare against values of the areas to be measured. Higher values indicate more moisture. In this way it is possible to detect moisture paths in the material irrespective of the material or material combinations (e.g. plaster with wallpaper).

10 Auto-Hold function

The last measurement value will continue to display for about 5 seconds after removing the device from the measured material. The Hold symbol flashes and the measured value last determined is displayed for this period of time. The device is ready for a new measurement as soon as the flashing stops and the measured value is reset to 0.

A 12%

Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.

!

Functional and operational safety is only warranted when the instrument is operated within the specified climatic conditions and is only used for those purposes for which it is designed. The assessment of measurement results and actions taken as a consequence lie in the user's scope of responsibility, depending on the given type of work.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.
