Page 3: Introduction
INTRODUCTION Thank you for selecting the MEP - Moisture Encounter Plus from Tramex. The Moisture Encounter Plus is a patented instrument, which enables non-invasive moisture measurement and detection in a wide range of building materials. The instrument operates on the principle that the electrical impedance of a material varies in proportion to its moisture content. -
Page 4: Instrument Features
INSTRUMENT FEATURES Your Moisture Encounter Plus employs advanced analogue and digital technology to enable the incorporation of many new features, which greatly extend the capability of the instrument. - Page 5 MEP USER GUIDE • Supply timeout is automatically extended if a change in meter reading is detected or if any button is pressed. • 10 second bleep warning on instrument sounder prior to end of supply timeout period. • Last used scale is memorized at supply timeout and automatically selected next time ON/OFF button is pressed.

Page 6: Operating Instructions
MEP USER GUIDE OPERATING INSTRUCTIONS The instrument face with brief notes on the push button controls and LED indicators is shown below. 84mm 1 = Moving coil meter. 2 = LED Indicators. 3 = Scale Select button. 4 = Power ON/OFF button. 5 = Hold button. - Page 7 To change scale, press/release the SCALE button until the LED opposite the required scale lights. Hold your Moisture Encounter Plus directly on the material being tested ensuring both conductive rubber electrodes are fully in contact with the surface.

MEP USER GUIDE To freeze readings press the HOLD/AUDIO but- ton once. While on Hold, the LED for the selected scale will flash slowly. This facility is extremely useful if readings are being taken in areas where it is difficult to see the instrument dial. To remove freeze, press the HOLD/AUDIO button again. - Page 9 MEP USER GUIDE Acceptable levels of moisture content depend on climatic conditions and we advise you check the levels acceptable in your area. The table on page 10 shows the approximate relationship between the ambient relative humidity and equilibrium moisture content in woods. As a rule of thumb and depending on climatic con- ditions, exterior wood is generally considered safe for painting when the moisture content is 14% or...
- Page 10 MEP USER GUIDE • Wood moisture content in excess of 18% - 20% may provide an environment for termite and wood-boring insects to thrive and multiply. Wood at these high levels can also support mold and biological growth. • Wood at 28% moisture content is considered to have reached fiber saturation point.

Page 11: Relative Humidity And Moisture Content
MEP USER GUIDE Relative humidity and moisture content The table below shows the approximate relationship between relative humidity and equilibrium moisture content of some woods. (These figures are approxi- mate values at a temperature of 70º F, and may vary for different species.) Relative Humidity Wood MC %... -
Page 12: Wood Flooring
Your Moisture Encounter Plus can be used to measure the moisture content of the wood floor to ensure it meets specification. Likewise it can be used to check, on a qualitative basis, through the floor covering, to identify elevated moisture in the substrate. -
Page 13: Notes On Specific Gravity (Sg)
MEP USER GUIDE Concrete Your Moisture Encounter Plus is not calibrated for concrete. The Tramex Concrete Encounter instru- ment is specifically designed for concrete flooring and is recommended where quantitative measure- ments are required. However a useful indication of the moisture condition of a concrete or sub floor can be obtained with the Moisture Encounter Plus set on the wall/brick mode. -
Page 14: How To Use The Wood Sg Tables
MEP USER GUIDE How to use the Wood SG tables When testing wood, which does not have an SG of 0.50, the meter reading can be adjusted by referring to the ta- bles shown on pages 14 and 15. For example, if the wood being tested has an SG of 0.70 and the meter reading is 17% (top row of table) then the adjusted moisture content reading can be found where the 0.70 SG row... -

MEP USER GUIDE WORKING WITH YOUR MOISTURE ENCOUNTER: Scale 2 Testing built-up roofing The presence of moisture in built-up roofs covered with multi-ply roofing felt, PVC, modified bitumen (torch-on) or other membranes, can cause blistering and splitting of the roof surfacing. In addition moisture can cause considerable damage to the contents and fabric of the building as well as heat loss through wet insulation. -
Page 18: Testing Drywall
Testing on ceramic tiles and other wall and floor coverings Your Moisture Encounter Plus can be used to detect and identify areas of elevated moisture within or behind most types of wall and floor coverings. For example the Moisture Encounter Plus can detect elevated moisture behind most types of ceramic tiles. - Page 19 MEP USER GUIDE Excess moisture trapped behind covering materials such as ceramic tiles, carpet, wall coverings etc can cause major problems. For instance, excess moisture behind ceramic tiles on drywall or other substrates can cause decay, delamination and mold growth, the longer these problems go undetected the worse the problem can get eventually leading to system failure.

Always press the electrodes firmly against the surface. The moisture profile of a wall can be determined by sliding your Moisture Encounter Plus across the surface where it will read through most paints, vinyl, wall coverings and even ceramic tiles. -
Page 21: Limitations
Limitations The Moisture Encounter Plus will not detect or measure moisture through any electrically conductive materials including metal sheeting or cladding, black EPDM roof- ing, butyl roofing, aluminum siding or wet surfaces. -
