INTRODUCTION
Congratulations on your purchase of the AccuMASTER XT
Moisture Meter. It's a tough, accurate tool for homeowners,
woodworkers, builders, home inspectors and flooring contractors.
Use the AccuMASTER XT to find moisture before it becomes a
costly problem. Easily check wood, lumber, drywall and concrete
before painting, sealing or treating. Quickly find water leaks in roofs,
walls and floors. With the AccuMASTER XT you'll always know
you're selecting dry lumber when buying wood for building or
selecting firewood for burning.
A Caution: Handle with care when removing protective cover.
The measuring pins are very sharp.
Remove the protective cap from the top of the
meter and attach it to the bottom end. Press
and hold the button to turn the unit on.
Press the button to select wood EN or
building material 3.
Carefully press the test pins into the material you
want to measure. The Moisture Content (MC) is
displayed as a percentage, and the “raindrops” in
the LCD show the different ranges of moisture
content — low, medium or high. Audible alert gets
faster as moisture content increases.
When measuring in a hard to reach place where
It's difficult to see the display, press the (* button
once to lock the MC reading. The + icon will
appear on LCD. Press the |) button again to
release the hold.

EXAMPLES OF TYPICAL PROJECTS USING THIS METER
Use your AccuMASTER XT to find leaks in drywall, carpeting, flooring
or ceilings caused by damaged roofs, flooding, burst pipes or
underground seepage. Find moisture early to avoid moisture-related
problems like mold and rotting wood.
You can also use your AccuMASTER XT to monitor moisture content
to determine the tangential, radial and longitudinal shrinkage of wood
for your woodworking projects and material readiness.
Buying Lumber and Wood — When purchasing
lumber for building projects or woodworking, make sure
your wood is dry enough to avoid shrinkage, cracking,
splitting or warping.
Firewood — Check to see if the wood is dry enough
to burn in stoves or fireplaces.
Prior to painting, tiling, varnishing or
wallpapering — Determine if your surface is ready
for application.
Gardening — Use the meter to monitor soil moisture
conditions to ensure healthy gardens.
Gently push the measuring pins into the material to be measured. Do not
use excessive force. Do not bang or forcefully push the pins into hard
materials such as concrete.
To more accurately measure moisture below the surface of hard,
non-porous materials, drill two small holes at the same width as the pins
and no deeper than the length of the pins. Then touch the tips of the
measuring pins to the bottom of the holes.
Always keep the measuring pins clean and replace the protective cover
when not in use.
