USER MANUAL MoistureFinder Compact Laserliner

General safety instructions – The device must only be used in accordance with its intended purpose and within the scope of the specications. – The measuring tools and accessories are not toys. Keep out of reach of children. – The structure of the device must not be modied in any way. – Do not expose the device to mechanical stress, extreme temperatures, moisture or signicant vibration. – The device must no longer be used if one or more of its functions fail or the battery charge is weak. 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 elds.MoistureFinder Compact

Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place. 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. HOLD

Automatic switch-off after 3 minutes. Hold symbol ashes until the value is stable.

Insert battery Open the battery compartment on the housing‘s rear side and insert a 9V battery. Correct polarity must be observed.10

Material characteristics This instrument has 4 selectable material characteristics. Before making a measure- ment, press the MODE button to select the appropriate material. Wet/dry LED indicator In addition to numeric measurement display in % of relative material moisture, the LED display also provides a material- dependent evaluation of moisture. The LED display bar becomes larger, from left to right, with increasing moisture content. The 12-position LED display is subdivided into 4 green (dry), 3 yellow (moist) and 5 red (wet) segments. Wet material causes an additional acoustic signal. The classication „dry“ means that materials in a heated room have reached a balanced moisture level and are thus suitable for further processing.

Screed cement screed CT-C30-F4 DIN EN 13813 Plaster gypsum plaster (machine plaster) in accordance with DIN EN 13279-1/plaster thickness = 10 mm Soft- wood low-density woods: e.g. spruce, pine, limewood, poplar, cedar, mahogany Hard- wood higher-density woods: e.g. beech, oak, ash, birch

The operating principle of the device can only determine the material moisture measurement in % and show the moisture content on the LED display when the material matches the specied internal material characteristics. – Make sure that the sensor pads make good contact with the material with no air inclusions. – The contact pressure compensates for unevenness of the surface and small dust particles. – Measured surface should be free of dust and dirt – Always take spot measurements while exerting a contact pressure of 2.5 kg. – For quick checks, while exerting light pressure, you can slide the device over the surface. (Look out for nails and pointed objects! Danger of injury and damage to sensor pads!) Measure again at the highest deection point while applying 2.5 kg contact pressure. – Keep at least a 5cm distance from metal objects – Metal pipes, electric lines and reinforcing steel can falsify measurement results – Always measure at several different spots Place the device such that the sensor pads fully rest on the material to be measured and exert a pressure of about

2.5 kg onto the surface to be

measured. TIP: Use scales to test the contact pressure. Always hold and press down the measuring device in the same way (see illustration).12

Maximum accuracy is achieved between 6% and 30% wood moisture. In very dry wood (< 6%) irregular moisture distribu- tion can be detected, in very wet wood (> 30%) saturation of the wood bres begins. Material relative moisture reference values, in %, for use with wood: – Outdoor usage: 12% … 19% – Use in unheated rooms: 12% … 16% – In heated rooms (12°C … 21°C): 9% … 13% – In heated rooms (> 21°C): 6% … 10% Example: 100% material moisture for 1kg of wet wood = 500g water. Functional and operational safety is only warranted when the instrument is operated within the specied climatic conditions and is only used for those purposes for which it is designed. The assessment of measure- ment results and actions taken as a consequence lie in the user‘s scope of responsibility, depending on the given type of work.

Plaster with wallpaper: Wallpaper affects the measurement to such an extent that the displayed value is falsied. Never- theless, the reading can still be used to compare the measure- ment at this spot with the measurement at another spot. The same is true of tiles, linoleum, vinyl and wood used to cover building materials. In some cases the measuring device can measure through these materials as long as they contain no metal. The reading should however be taken as a relative measured value. Plaster: Plaster mode is congured for a plaster thickness of 10 mm applied on concrete, lime-sand brick, cellular concrete. Other masonry must be checked beforehand. Wood: The measured depth in wood is 30mm maximum but does vary somewhat with differing wood densities. Measure- ments made on thin wood boards should, if possible, be made on a stack of these boards as otherwise the measurement will be too low. Measurements made on installed wooden structures are inuenced by the structural conditions and their chemical treatments (e.g. paints) with various materials. Thus such measurements should only be viewed relatively.MoistureFinder Compact
