Advanced Setup Instructions - General MMD900 User Manual

To gauge the internal or surface moisture level of a material, enter REL
mode by pressing the Mode button as many times as necessary until the text
REL appears on the top line of the LCD. To establish a baseline for relative
readings, press the area of the back cover marked "Pinless Sensor" against a
material known to be completely dry. The meter should read "0" on both the
LCD and LED bar graphs. Then press the back of the meter against one or more
points on the target surface and compare the readings.
Some measurement tips:
1. For best results, press the pinless sensor against a flat area of the target
material.
2. When holding the sensor against a material, keep your hand and fingers as
far away from the sensing area as possible.
3. The dimensions of the target surface should be at least as large as those of
the sensing area: 1.6 x 1.6 in. (40 x 40mm).
4. Never use force to drive the test pins into a hard surface.
5. Measurements of wood are skewed by two variables: ambient humidity and
the density of the wood species. Please be aware of the effect of these
variables.
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
the icon on the top line of the LCD). If the icon is present, scan the
material while paying attention to the beeper's frequency. The faster the beeper
beeps, the wetter an area is. Near the high end of the meter's measurement
range, the beeping sounds almost constant.
If the beeper has been disabled, to re-enable it you must power off the meter
and then change the beeper's default setting using the Advanced Setup
instructions in the next section.
To hold a measurement, press the
