Frequently Asked Questions - MoistureFinder Compact Laserliner

How to install the battery?

Open the battery compartment on the back of the device and insert a 9V (6LR61) battery respecting polarity. Close the compartment.

What materials can be measured?

The device measures moisture in softwood, hardwood, cement screed and plaster coating. It has four characteristic curves selectable via the MODE button.

What do the colored LEDs mean?

The 12 LEDs indicate the moisture level: 0-4 green = dry, 5-7 yellow = damp, 8-12 red = wet. An acoustic signal sounds in the red zone.

How to perform an accurate measurement?

Place the detection pads flat on the surface and apply a pressure of about 2.5 kg. Keep the same pressure for each measurement. The surface must be clean and dust-free.

What to do if the device does not turn on?

Check the battery: open the compartment and make sure a 9V battery is correctly installed and not used. Replace if necessary.

How to interpret the percentage values?

The values indicate the relative moisture content of the material. For example, for wood intended for heated rooms (12-21°C), a value of 9% to 13% is normal. Refer to the indicative table in the manual.

Can I measure through wallpaper or tiles?

Yes, but the results will be relative because these coverings influence the measurement. Use the values to compare different points, not as absolute measurement. Avoid metallic materials.

What is the measurement depth?

For wood, the maximum depth is about 30 mm, depending on density. For construction materials, the measurement is mainly superficial (10 mm thick coating for plaster mode).

How to maintain the device?

Clean it with a slightly damp cloth, without chemicals or solvents. Remove the battery if you do not use it for a long time. Store it in a dry and clean place.

Where to find additional information?

Consult the complete user manual on the Laserliner website or via the link packd.li/ll/apr/in mentioned in the manual. You will find safety instructions, warranty conditions, and recycling information.

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 capacitive measuring principle. Moisture-dependent permittivity of the material is measured between 2 conductive sensor pads on the underside of the device and the material moisture is calculated in % with internal material-dependent characteristics. The intended purpose of the device is the non-destructive assessment of moisture content in wood, cement screed and plaster.

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.

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.

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.

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.

1 Insert battery

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

2 ON

Automatic switch-off after 3 minutes.

HOLD

Hold symbol flashes until the value is stable.

B Material characteristics

This instrument has 4 selectable material characteristics. Before making a measurement, press the MODE button to select the appropriate material.

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

4 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 classification „dry“ means that materials in a heated room have reached a balanced moisture level and are thus suitable for further processing.

5 Application notices

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).

• 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 deflection point while applying 2.5 kg contact pressure.
• Keep at least a 5 cm distance from metal objects
• Metal pipes, electric lines and reinforcing steel can falsify measurement results
• Always measure at several different spots

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 specified internal material characteristics.

Plaster with wallpaper: Wallpaper affects the measurement to such an extent that the displayed value is falsified. Nevertheless, the reading can still be used to compare the measurement 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 configured 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 30 mm maximum but does vary somewhat with differing wood densities. Measurements 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 influenced by the structural conditions and their chemical treatments (e.g. paints) with various materials. Thus such measurements should only be viewed relatively.

Maximum accuracy is achieved between 6% and 30% wood moisture. In very dry wood (< 6%) irregular moisture distribution can be detected, in very wet wood (> 30%) saturation of the wood fibres 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 1 kg of wet wood = 500 g water.

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.
