082.015A DampFinder Compact Moisture Measuring Instrument
Instruction Manual

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 device detects and evaluates the material moisture content of wood and building materials by way of electric resistance measurement. The displayed value  (wood) or the calculated value (building materials) is material moisture in % with respect to dry mass. Example: 100% material moisture for 1 kg of wet wood = 500 g water.
The measuring instrument also features a material-independent index mode.

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 a 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.

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 limits 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.

Inserting batteries (see Fig. A, Page 02)
Open the battery compartment and insert batteries according to the symbols. Be sure to pay attention to polarity.
Change measuring prods (see Fig. B, Page 02)

When the device is turned on, the display will show the ambient temperature for 3 seconds.

To change the measuring mode

The device starts with the measuring mode last selected.

Self-test function

Determine 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.
Carry out several comparison measurements across the grain structure.
The table shows which wood types are grouped under A and B.

Index mode (Determine building moisture)

The universal index mode is used to compare measuring points and therefore to ascertain moisture. The moisture content of building materials can be additionally determined in % with the aid of the conversion table.

Be aware that walls (or surfaces) with differing material structures, or even variations in material composition, can cause measurement results to be falsified. Perform multiple comparative measurements.
You read off the measurement results from the following index scale and convert them to % with the aid of the table.

Example
Building material: Anhydrite screed
Measured value: 280
Result: 0.1% material moisture

If there is no response when measuring, 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.
The symbol of the selected mode flashes and the measured value last determined is displayed. The device is ready for a new measurement as soon as the flashing stops and the measured value is reset to 0.

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 lies in the user‘s scope of responsibility, depending on the given type of work.

Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents, scouring agents, or solvents.
Remove the battery(ies) before storing it for longer periods.
Store the device in a clean and dry place.

Calibration
The measuring device should be calibrated and tested on a regular basis to ensure it is accurate and working properly.
We recommend the measuring device is calibrated every 1 – 2 years. If necessary, contact your distributor or the UMAREX-LASER LINER service department.
