Frequently Asked Questions - DampCheck Laserliner

How to replace the batteries of the DampCheck?

Open the battery compartment on the back of the device. Insert 4 LR44 (AG13) batteries respecting the indicated polarity. A low battery symbol appears on the screen when the batteries need to be replaced.

How to measure wood moisture?

Select wood mode by pressing the SET button for 3 seconds. Push the electrodes into the wood (untreated surface, without branches, dirt, or resin). The device displays the moisture percentage and the LEDs indicate if the wood is dry (green), damp (yellow), or wet (red).

What do the colored LEDs mean?

The green LED indicates a dry material (wood 6-16%, materials 0.2-0.7%), yellow damp (wood 16-20%, materials 0.7-0.9%), and red wet (wood >20%, materials >0.9%).

How to switch between wood, building materials, and temperature modes?

The device starts on the last mode used. To change, press and hold the SET button for 3 seconds until the symbol flashes, then release. Briefly press SET to cycle through modes: wood, materials, temperature. The device validates automatically after a few seconds of inactivity.

What to do if the measurement seems incorrect?

Check that no pipes (electrical, water) are under the measurement surface and that there is no metal background. Take several measurements at different points for comparison. Make sure the batteries are sufficiently charged. If the problem persists, annual calibration is recommended.

Can this device measure moisture in concrete or plaster?

Yes, it has a mode for building materials (range 0.2-2.9%). The built-in characteristic curve is adapted to plaster. For other materials, use the device as a comparative reference value rather than absolute.

How deep to insert the electrodes?

Insert the electrodes as far as possible into the material being measured without forcing, to avoid damaging the device. For hard materials, pre-drill a hole if necessary. Remove the device by rocking it from side to side.

My DampCheck turns off by itself, is this normal?

Yes, the device turns off automatically after 15 seconds of inactivity to save batteries. For continuous use, hold down the function button or reactivate it.

How to clean the DampCheck?

Clean the components with a slightly damp cloth. Do not use cleaning agents, abrasives, or solvents. Remove the batteries before long-term storage and store the device in a dry, clean place.

Where should I dispose of the device at the end of its life?

In accordance with the WEEE Directive, this product must not be disposed of with household waste. Take it to a collection point for waste electrical and electronic equipment. Used batteries must also be recycled separately.

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. The device can also be set up to measure the ambient temperature.

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.

1 Inserting batteries

Open the battery compartment and insert batteries according to the symbols. Be sure to pay attention to polarity.

The „Battery Charge“ symbol (c) appears on the display when the battery charge is low.

2 ON HOLD OFF

The device switches off automatically if left idle for 15 seconds.

3 To change measuring mode

The device starts with the measuring mode last selected. To select the mode, press and hold the Set button for 3 seconds or briefly wait until the symbol stops flashing.

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.

4 To measure material moisture

Dry/wet indicator

In addition to the numerical moisture value, the LEDs (green, yellow and red) provide a rough estimation whether the material is dry (green), moist (yellow) or wet (red).

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.

Wood moisture measuring range

< 6% All LEDs off
≥ 6% to < 16% Green LED flashing
≥ 16% to < 20% Yellow LED flashing
≥ 20% Red LED flashing

The following types of wood in Group A can be read off directly: beech, linden, willow, ebony and teak. A correction factor of 2 - 3% must be added when measuring types of wood in Group B (oak, maple, alder, spruce, birch).

!

Wood with a relative material moisture level greater than 20% should not be used for burning. The optimum calorific value of wood is achieved at a level of <15%.

Mineral building materials

Be aware that walls (or surfaces) made of several different materials, or even variations in the material's consistency, can cause measurement results to be falsified. Perform multiple comparative measurements.

Building moisture measuring range

< 0,2% All LEDs off
≥ 0,2% to < 0,7% Green LED flashing
≥ 0,7% to < 0,9% Yellow LED flashing
≥ 0,9% Red LED flashing

The integrated building material characteristic is adapted to gypsum plaster. The measuring ranges for building materials differ significantly and also vary between manufacturers. The integrated characteristics does therefore not apply to all possible building materials. If necessary, check values using other measuring methods such as the Darr method.

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).

Temperature measurement

To measure the ambient temperature switch the device to ^ C or ^ F.

!

The sensor may take longer to settle under conditions where temperatures fluctuate considerably.

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.
