SETUP INSTRUCTIONS

INSTALL BATTERY

To open the battery compartment, turn the meter over and lift the tab at the top
of the battery compartment cover (Fig. 1, Callout N). Remove the cover and set
it aside. Then plug the included "9V" battery into the wired socket inside the
compartment. The terminals of the battery and the socket mate in only one
way, with the smaller male terminal plugging into the larger female terminal.
Close the battery compartment by replacing its cover and snapping it shut.

OPERATING INSTRUCTIONS

To power on the meter, press and hold the ON/OFF button for at least three
seconds. (To power off the meter, follow the same instruction.)
To measure the moisture level of drywall, masonry, hardwood or

softwood, press the or button until the name of that material appears on
the LCD (WALL is short for drywall). Then scan the material by gently pressing
the inductive sensing area (Fig. 1, Callout M) on the back of the meter against
the material. The LCD will read out the material's moisture content in the unit
%WME (Wood Moisture Equivalent).
Simultaneously, one or more bar graph LEDs will illuminate to place the
material's moisture level within a spectrum bounded by "dry" and "wet". The
color of the illuminated LED furthest to the right indicates which %WME band
contains the material (see the Specifications section on p. 7 for the bands'
boundaries).
To hold a reading, press the HOLD button briefly. The display will show the
held value, along with a lock icon above the % sign. If the reading is above the
alarm limit for that material, pressing the HOLD button will silence the beeper.

MEASUREMENT TIPS

For maximum accuracy, press the sensing area against a flat area of the
material.
Ideally, the material should be at least 3/4 in. thick. That is the meter's
maximum measurement depth and the thickness it is calibrated for. If your
sample is too thin, the meter will measure material beneath it as well and
produce an inaccurate reading. One way to compensate for thin samples is to
stack them.
