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 lb of wet wood = .5 lb 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 die- rent 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.
Wood

Mineral building materials
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. Read measurement results from the left-hand wood
moisture scale.
Refer to the conversion table below in order to obtain more precise measurements for dierent materials.
Be aware that walls (or sur­faces) made of several dierent materials, or even variations in the material‘s consistency, can cause measurement results to be falsied. Perform multiple
comparative measurements.
Read measurement results from the right-hand building
materials scale.
Refer to the conversion table below in order to obtain more precise measurements for dierent materials.

Table notices:
Measurements indicated on the instrument‘s dual-scale are based on the common built-in material characteristics for wood and building materials. More precise results can be obtained for the given wood or building material when the indicated measurement is referenced to the conversion table.
Example: Measurement on the left scale: 24%, corresponds to 1,2% for gypsum plaster. Values with a grey background are considered to be wet.

General notices:
Functional and operational safety is only warranted when the instrument is operated within the specied climatic conditions and is only used for those purposes for which it is designed. Responsibility for the interpretation of measurement results and consequent actions taken lie entirely with the user.
Warranty
The warranty period is 1 year from the date of purchase. The warranty covers all material or manufacturing defects occurring during this time. The following are excluded from warranty: Damage due to improper use (e.g. operation with wrong type of current/voltage, connection to unsuitable power source, fall onto hard surface, etc.) or improper storage, normal wear and tear, and defects which only insignicantly impair the value or suitability for use. Any tampe persons will render this warranty void. In the event that you need to claim warranty, please take the complete device together with all information and the invoice to one of our dealers and have them contact us.
