Function / Application
This material moisture device 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.

[5] Select wood group (A, B, C)

Just which wood types are grouped under A, B and C can be found in the table in Section 10.

[6] Select building material (01, 02, 03, 04, 05, 06, 07, 08)

Just which building materials are grouped under 01 to 08 can be found in the table in Section 11.

[7] Measuring material moisture

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 device. Always pull the device 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 device when it is not in use or being transported.

[8] 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.

[9] 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 … C. Please set the measuring device for the respective group in which the type of wood to be measured is found (see Step 5). A similar setting must also be made for measurements performed on building materials (see Step 6). Building materials are divided into groups 01 through 08.

[12] Wet/dry indicator

In addition to the measured value, the wet/dry indicator shows the moisture evaluation. This indicator is tuned by the material characteristics (A, B, C; 01, 02, 03, 04, 05, 06, 07, 08) stored in the measuring device. This evaluation is subdivided into 12 steps and it makes an evaluation of the measured material easier. The display is to be considered as a general indication and not a final evaluation.

13 Index mode

Index mode is used to rapidly locate moisture with comparative measurements, without a direct output of material moisture in %. The output value (0 through 1000) is an indexed value that increases as material moisture becomes greater. Measurements made in index mode are independent of material type and particularly useful with materials for which no characteristics are stored. When comparative measurements reveal strongly deviating values, the course of moisture in the material can be localized quickly. In addition to those materials with characteristics stored in the measuring device, index mode makes it possible to measure other building materials (09 … 31), refer to the table at the right (See index mode conversion tables). The displayed value (0 through 1000) serves as the basis.

Activate index mode in your measuring device (Step 13b). In order to determine the degree of moisture in a type of building material, first find the material number for the building material to be measured. Following this, read the measured value from the scale displayed on the measuring device for index mode. Now determine the value for the corresponding material number in the table. If this value has a dark grey background, the material is to be classified as “wet”, values without coloured background are considered to be “dry”.

[13b]

[14] Programmable wet/dry indicator in index mode

The wet/dry indicator can be programmed to the already predefined values especially for index mode. This produces a new setting for the “wet” and “dry” threshold value (see arrows).

[16] Wood moisture/temperature compensation

The relative material moisture of wood is dependent on temperature. The device automatically compensates for different wood temperatures by measuring the ambient temperature and using it for the internal calculation.

To increase measuring accuracy, however, the measuring device also offers an option for setting the temperature manually (see Step 16b). This value is not stored and must be set again each time the device is switched on.

[16b]

[17] LCD backlight

LED display illumination can be varied with 3 different settings:

AUTO: Display illumination switches off during periods of inactivity and switches on again automatically for measurement procedures.
ON: Display illumination remains on permanently.
OFF: Display illumination remains off permanently.

The setting is stored and remains in effect until it is changed manually.

[18] Temperature units of measure setting

The units of measure for ambient temperature and material compensation can be set to either °C or °F. The setting is stored and remains in effect until it is changed manually.

[19] Self-test function

Data transfer

The device features a Bluetooth® function that enables wireless data transfer to mobile devices with a Bluetooth® interface (such as a smartphone or tablet).

The system prerequisites for a Bluetooth®* connection are specified at http://laserliner.com/info?an=damacopl

The device can set up a Bluetooth®* connection with Bluetooth 4.0 compatible devices.

The range is set to a maximum distance of 10 m from the terminal device and greatly depends on the ambient conditions such as the thickness and composition of walls, sources of interference as well as the transmit / receive properties of the terminal device.

Once it has been activated, Bluetooth®* remains switched on indefinitely as the radio system is designed with exceptionally low power consumption. A mobile device can link up to the active measuring device via an app.

Application (app)

An app is required to use the Bluetooth®* function. You can download the app from the corresponding stores for the specific type of terminal device:

| Make sure that the Bluetooth®* interface of the mobile device is activated.
---|---

After starting the app and activating the Bluetooth®* function, a connection can be set up between a mobile device and the measuring device. If the app detects several active measuring devices, select the matching device.

This measuring device can be connected automatically the next time it is switched on.

• The Bluetooth® word mark and the logo are registered trademarks of Bluetooth SIG Inc.

| 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.
