TechScan™ VERSION 1.1 OWNER’S MANUAL INTRODUCTION Thank you for purchasing TechScan, a multi-purpose meter that can be used in many applications including water damage restoration, home inspection, indoor air quality, woodworking, flooring installation. TechScan provides a fast, effective way to identify moisture problems and determine if further action must be taken.
reference points against which subsequent readings are compared. One should not expect that the reference scales for meters of different brands and types (resistance /capacitance) will read alike on the same material. The benchmark may be different from one meter type/brand to another because a given meters’ response depends on the material used for calibration and on the meter’s range. SWITCH KEY FUNCTIONS 1.
4. Down Arrow Key: Press and hold to decrease the alarm setting. 5. Up Arrow Key: Press and hold to increase the alarm setting. OPERATION Checking the Battery and Calibration The meter automatically checks the battery level when it is turned on. If the battery voltage is not high enough for reliable operation, all indicators will flash for a few seconds. Replace the battery with a new one (9v alkaline). To check the meter’s calibration, turn the meter on. Press and hold the Cal Check key.
Auto Shut-off The meter automatically turns off when no keys are pressed for three minutes. Five seconds before the meter turns off, the beeper will sound and the active Scale indicator will flash. To prevent the meter from turning off, press any key before the meter turns off. HELPFUL TIPS FOR USING TECHSCAN TO MEASURE MC IN WOOD: Set the scale to “Wood”. The entire sensor plate should be in contact with the surface of the board. The sensor plate measures 2-1/2” x 3-1/2”.
The “right” moisture content depends on the final use of the wood and is climate-driven. Recommended moisture content for indoor woodworking / furniture ranges from 6%-9%. Outdoor construction grade lumber is usually 19% or less; 10%-15% for safe painting or staining. Corrections for Specific Gravity (SG) Measurements obtained with capacitance type moisture meters such as TechScan are greatly influenced by the specific gravity of the material (specifically the wood) being measured.
The meter’s RF signal penetrates to ¾” – 1”. Material underneath or behind the surface being tested may influence the readings. This includes metal studs, wiring, and in the case of concrete, rebar and aggregate. The meter works best on smooth, clean surfaces. Surface moisture slightly increases the readings. Wipe obvious moisture from the board surface to minimize this effect.
If you suspect a problem conduct 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. If you believe a problem exists, use TechScan as a quick scanning tool to determine the general location of the moisture. Then use a pin- type meter to better identify exact problem areas and depth of moisture intrusion.
