INTRODUCTION Accuscan is a multi-purpose meter, which can be used in many applications, such as flooring, water restoration/IAQ, woodworking and home inspection. It is a fast, effective way to identify moisture problems and determine if further action must be taken. Accuscan is a capacitance-type moisture meter, using the relationship between the moisture content and the dielectric properties of the material under test.
BEFORE YOU BEGIN Button Functions ! STAY ON BUTTON - Turns the meter “on.” Also keeps the meter “on” continuously if pressed and held. @ REFERENCE SCALE BUTTON - Selects reference scale and turns the meter “on.” Also performs an auto calibration. The LED blinks red when this button is pressed. # CHECK BUTTON - Verifies that the meter is functioning properly and that the battery voltage is sufficient. $ WOOD SCALE BUTTON - Selects wood scale and turns the meter “on.” Also performs an auto calibration.
METER/BATTERY CHECK hHold the meter in the air and away from any object. Your fingers must not make contact with the sensor plate while performing this function. hPress and hold the check button (3) until the green light stops blinking. hThe battery voltage is sufficient if the needle pointer moves to within the green band (20%) on the wood scale. Any reading within this green band on the dial is acceptable. Make sure the sensor pad is not making contact with anything when checking the meter.
APPLICATION NOTES USING THE 6-40% WOOD SCALE Testing Wood Flooring hBefore installing a floor, make sure that the moisture content of the sub floor and the flooring are within 2%-4% of each other. Most flooring manufacturers also recommend that the installer allow the floor to acclimate in its environment for several days before installation. During this period, check both the floor and the sub floor to ensure that moisture levels of both materials remain stable.
hSurface moisture increases the readings. Depending on the application, we recommend using a Delmhorst pin meter with insulated pins to determine if a normal gradient (wet core to drier outer surface) is present or if surface moisture has just soaked into the board. USING THE 0-100 REFERENCE SCALE: read the section on page 3 again before proceeding Testing Concrete Slabs for Flooring Applications hMoisture meters are an effective tool to check moisture in concrete.
Key Factors to Consider hThe age of the slab. National Wood Flooring Association guidelines specify to wait at least 30 days after the slab is laid before checking moisture content.
Testing EIFS (Exterior Insulation & Finish Systems) hMoisture intrusion problems in EIFS (also known as synthetic stucco) stem from leaking window and door frames, improper use of or lack of sealant, and faulty installation of flashing. hIf you suspect a problem take a visual inspection. Look for gaps around windows, doors, air conditioning units, light fixtures, hose bibs, dryer vents and other areas of potential penetration. Also look for visible signs of water damage.
CARE FOR YOUR METER To keep your meter in good working order: h Store meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is not in use. h Change the 9-Volt battery as needed. Continued use with a low battery may cause the meter to go out of calibration. hClean the meter with any biodegradable cleaner. Use the cleaner sparingly and on external parts only. h Remove the battery if the meter will not to be used for one month or longer.
hWarranty repairs will be returned at no charge if shipped within the U.S. via UPS Ground Service. Freight charges for expedited services (i.e., Federal Express, UPS/2 Day, UPS/1 Day, etc.) are the customer’s responsibility and will be charged as per the above terms.
