2. Measuring the change in the material’s capacitance produced by the slight spreading of a local electric field generated by the meter. When the meter is powered on, two plates inside the back of the MMD900’s housing are charged with opposite polarity and pulsed at a high frequency. - Page 4 1) Moisture close to the surface has a greater effect on a reading than moisture deep below it; and 2) The pins of the MMD900 are too short to be driven deep into a hard material. The pins at the top of the meter are 15mm (0.6 in.) long and the pins on the remote probe are 10mm (0.4 in.) long.

• The 40-LED analog bar graph groups LEDs of three different colors (green, yellow and red) into low, medium and high moisture bands. Each readout (%WME or REL) can be accompanied by a beeper that can be programmed to sound in different ways in response to different moisture levels or operations. The correlations make it easy to use sight and/or sound to pinpoint areas of peak or relative wetness. -

Page 10: Advanced Setup Instructions
To scan a material for an area of peak wetness in either measurement mode (%WME or REL), first make sure that the beeper is enabled (indicated by icon on the top line of the LCD). If the icon is present, scan the material while paying attention to the beeper’s frequency. - Page 11 It’s important to understand that in Setup mode you have 30 seconds to confirm the setting of each Option. If you take longer than 30 seconds to confirm any setting, the MMD900 will automatically exit Setup mode and enter Measurement mode.
