⇒ Set the meter’s parameters as described previously in the owners’ manual. If the species (construction-grade only) is unknown, set the meter to the reference calibration, Douglas Fir and take the readings at face value. ⇒ To take a reading, align the contact pins parallel to the grain and push them to their full penetration into the wood, if possible. Insulated pins read only at the tip and can be driven to the desired depth. ⇒ Press the SELECT button and read the moisture content on the meter scale.
will move into a hygroscopic (wood) floor, or build-up pressure under a non-breathing synthetic floor, causing delamination. Taking a surface reading: Drive two hardened-steel masonry nails about 3/4" apart into the finish coat of concrete floor. Drive them about 1/8" deep so they make firm contact with the concrete and do not move when touched. Ø Touch the nails with the contact pins. Ø Press the select key and read the meter. If the meter reads less than “68”, the surface is dry.
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.
CARE OF YOUR METER Ø Store your meter in a clean, dry place. The protective carrying case provided is an ideal storage place when the meter is not in use. If the meter has been left in a hot or cold environment overnight or for an extended period, the calibration of the pin less mode may be adversely affected. Under these conditions, allow the meter to acclimate to the temperature conditions in which it will be used for minimum 1-2 hours, or as long as possible. Ø Change contact pins as needed.
