TESTING DRYWALL

Set the meter scale for Sheetrock® as described in the Create/Modify a Job section on page

11.

To take a reading, push the contact pins into the Sheetrock® to their full penetration, if

possible.

Press the SELECT button and read the moisture content on the meter scale. The meter

displays the %MC for two seconds.


Note:

Readings between 0.1% and 0.5% indicate a sufficiently dry moisture level.
Readings between 0.5% and 1% indicate a borderline situation. Readings
greater than 1% indicate material that is too wet for painting or wallpaper. A
reading above 1% also indicates enough moisture present to allow mold growth
to occur but only if other factors are also present such as a high RH level and
food source.
