Taking Measurements
Be sure to press down firmly on the center of the meter with approximately 3 pounds of force to ensure
good sensor plate contact with the wood surface. This is especially important on rough-sawn lumber. Do
not take readings where there is a noticeable defect or knot in the lumber.
If there is visible surface moisture or water, wipe off any excess, and let the surface of the wood dry-out
for a couple of minutes, then take the reading. If possible, turn the board over and measure the other side.
If the thickness of the piece is greater than 3 inches, it is a good idea to take measurements on both sides.
Ensure that there is nothing (especially your hand or metal) under the material you are measuring. The
actual moisture sensing area is a 2½ inch by 2½ inch rectangle on the meter’s backside (opposite side of
the display panel). In order to take a valid measurement, this sensing area must be completely covered by
the wood you are measuring. If the sensing area is not completely covered, your moisture reading will be
inaccurate.
Additional meter corrections may be necessary if you are measuring Raft Wood (salt water permeated), or
lumber treated with CCA, ACQ or any other treatment with metallic or other components that might bias
the moisture readings.

Meter Calibration
The meter has been calibrated at the factory and should not require re-calibration. If you need to have the
calibration verified, please contact the Wagner Meters Sales Department to purchase a calibration
verification block if you don’t already have one. Should the meter need to have a calibration adjustment,
it will need to be returned to Wagner Meters Technical Services Department.
Meter Storage
For a long service life, it is important to store your meter properly. Avoid excessively hot or cold
locations. Do not store the meter in an area with excessive electro-magnetic interference, such as near an
electric motor, or where it could be crushed, such as in front of a forklift. Do not leave the meter in an
operating kiln during the drying cycle.
