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 minimize 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.
Overview
-
Wood group A,
Moisture in % -
12 position wet/dry
- LED indicator
- LED 0…4 (green) = dry
- LED 5…7 (yellow) = moist
- LED 8…12 (red) = wet
- LED 11…12 (red):
- Low battery charge

On/Off switch
ON/OFF
The device switches itself off automati-cally 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.
Self-test function
4 green LEDs and one yellow LED light up. 
Wood groups
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.
Wet/dry LED indicator
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.
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 color) 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.
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.
