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”.

Readings obtained with TechScan and pin-less moisture meters in general,
are affected by the amount of pressure applied to the material. Apply and
maintain uniform, firm pressure to the meter when taking readings.

The meter’s RF signal penetrates to ¾” – 1”. When measuring thinner
material, some materials underneath the wood may influence the readings.
Place a piece of glass, rubber or styrofoam under the sample to avoid false
readings. Test the insulating material with the meter first to confirm it provides
the necessary insulation.

The meter works best on smooth lumber and surfaces. Rough, uneven, or
cupped boards yield lower readings due to the air pockets between the
sensor plate and the surface. Avoid readings on knots or splits.

Surface moisture slightly increases the readings. Wipe obvious moisture from
the board surface to minimize this effect.

The meter is influenced by a moisture gradient but cannot detect it. If you
suspect a gradient, use a Delmhorst resistance-type meter with insulated pins
to determine if a normal gradient (wet core to drier outer surface) is present or
if surface moisture has just soaked into the board.

Before installing a wood floor, if possible allow the flooring to acclimate in its
environment for several days before installation. During this period, check
both the floor and the sub floor to ensure that moisture levels of both
materials remain stable and are within recommended MC guidelines.
