Frequently Asked Questions - WoodTester Compact Laserliner

How does the WoodTester Compact work?

It measures wood moisture via electrical resistance. Insert the electrodes into the wood and read the percentage on the LED display. Values are referenced to dry mass.

What are the wood groups and how do I use them?

Group A (beech, linden, willow, ebony) uses the upper scale; Group B (oak, maple, alder, spruce, birch, ash) uses the lower scale. Select the group using the ON/OFF switch (press to change).

What do the LED colors mean?

Green = dry (bars 0-4), yellow = damp (bars 5-7), red = wet (bars 8-12). For Group B, compare the amplitude with the lower color scale.

Which battery to use and how long does it last?

Use a 9V 6LR61 battery. Battery life is approximately 40 hours. The device automatically turns off after 3 minutes to save battery.

What to do if no LED lights up during a measurement?

The material may be too dry. Perform a self-test by inserting the electrodes into the protective cap: all LEDs should light up. If not, check the battery.

How to interpret a value of 13% for Group A?

13% corresponds to a green LED (dry) according to the Group A scale. The wood is considered dry for woodworking purposes.

Can I measure moisture of materials other than wood?

No, the device is specially calibrated for wood with two species groups. It is not suitable for building materials like plaster or concrete.

Where to take a measurement on a piece of wood?

Choose an untreated area, free of knots, dirt, or resin. Avoid end grain as the wood dries faster there and skews the measurement.

How to maintain the device?

Clean the electrodes with a dry cloth after each use. Always replace the protective cap to avoid injury and protect the device. Store in a dry place.

What to do in case of malfunction or repair?

Consult the complete manual or website www.laserliner.com/info. The device is not user-repairable; contact after-sales service if issues arise. It complies with the WEEE directive for recycling.

Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. Follow the instructions they contain. Safely keep these documents for future reference.

Function/application: This material moisture device detects and evaluates the material moisture content of wood 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.

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.

B ON/OFF

The device switches itself off automatically after 3 minutes to save battery power. If the device has switched itself off, use the On/Off switch again to switch it on again.

4 Self-test function

4 green LEDs and one yellow LED light up.

4 green, 3 yellow and 5 red LEDs illuminate.

6 Determining wood moisture

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.

7a Wet/dry LED indicator for group A

After switching the device on, all 12 LEDs will illuminate briefly. Thereafter, the first green LED will blink continuously. The device is now ready to use. If a measurement for a group A wood is made, the material's moisture in % will be displayed in the upper scale. 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. The moisture content of wood can be determined both from the percentage figure as well as from the LED colour. Example shown: 13 %, green LED = dry.

7b Wet/dry LED indicator for group B

If a measurement for a group B wood is now made, the material's moisture in % will be displayed in the lower scale. In this case, the right-most illuminated LED (regardless of colour) and the colour-scale beneath it are used to determine if the wood is to be classified as „dry“, „moist“ or „wet“. Evaluation is now based on the lower colour scale. Green = dry, yellow = moist, red = wet. Example shown: 23 %, red section of the lower scale = wet.

!

If a measurement should produce no change of the LEDs, it is possible that the measured material is too dry. Perform a self-test of the device with the protective cap to make sure the device is in good working order.

8 Auto-Hold function

The last measurement value will continue to display for about 5 seconds after removing the device from the measured material. During this period the LEDs will blink and show the last measurement value. As soon as only the first green LED blinks, the device is ready to make a new measurement.

!

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.
