INTRODUCTION
Moisture meters MT-10 can be used to measure the
amount of water in the wood or building material so
that the woodworker can determine if it is suitable for
the intended purpose. Building inspectors, carpenters,
hobbyists, and other woodworkers often are required
to have moisture meters. Wood flooring installers, for
example, have to verify that the moisture of the wood
matches the relative humidity in the air of the building.
If this step is skipped, a vast array of problems may
present itself: cracking, cupping, crowning, buckling,
sunken joints, and cracked finishes.
OPERATION
1. Press the POWER ON/OFF button once to turn on
the instrument
2. Selecting desired Measurement Mode
a) After the instrument has been turned on, press
and hold down the button for about 3 seconds
to enter Setting Mode (reading disappears,

the button until the meter is in the desired
measurement mode and the corresponding
