Introduction
Congratulations!
You have purchased one of the most accurate
moisture measurement instruments for
wood in the world. Using patented
electromagnetic wave technology, Wagner
hand-held meters have been proven by
universities and institutes worldwide to
provide superior measurement results.
Utilizing an electro-magnetic field, your
Wagner moisture meter measures a
relatively large cross-sectional area each
time you take a reading, giving you a far
better representation than other technologies
of the true moisture content of your wood.
Pin-type meters do not provide this, only
measuring a very small area, and only at a
particular depth. Very short, non-insulated
pins are especially prone to just reading the
surface of your wood.

Introduction Continued. . .
Your Wagner meter measures the moisture
content in a 11/2 inch wide by 21/2 inch long
by 3/4 inch thick area of your wood. This
closely approximates the full-thickness
cross-section method used when performing
the ASTM D 4442-92 Oven Dry lab test for
determining moisture content in wood. This
ASTM standard (and its international
counterparts) is the standard to which all
moisture meters for wood are compared for
accuracy. Wagner technology has been
proven in many studies to provide some of
the most accurate results in the industry
when compared to this worldwide standard.
The Wagner MMC-200 Series Moisture
Meters utilize the latest design features
available in moisture measurement
technology. They are designed to fit
comfortably in a jacket pocket or toolbox,
and are ideal for anyone who needs a
professional quality tool to inspect wood or
4
wood products for accurate moisture
content. They are popular with flooring
installers, woodworkers, cabinet and
furniture makers, contractors, and quality
assurance inspectors.
Other important features of Wagner handheld meters include:
• The "Wood-Friendly"™ MMC-200 series
meters use advanced electromagnetic
wave technology to accurately measure
wood moisture content* to a depth of 3/
4
inch. The MMC-205 can read values from
5% to 20%, while the MMC-210 can read
5% to 30%. The MMC-220 can read 5%
to 30% at settings up to .80 SG. Note: If
the MMC220 species setting value
selected is more than 80, the maximum
moisture content reading attainable will
be lower than 30%.

• Useful for inspections on many types of
materials, including solid and laminated
wood products.
• Selectable wood species setting eliminates
complicated and time consuming wood
species adjustment corrections.
• Easy to read digital display read-out scaled
in 0.1% increments (1.0% for the MMC-
205).
• Virtually unaffected by wood temperature
or surface moisture. **
*Confirmed in university study–
information available upon request.
**Contact Wagner technical support for
guidelines when wood is frozen.

Operational Instructions—MMC 205
On/Off/Species Button:
When the meter is Off,
momentarily pressing and
releasing this button will cause
the meter to turn On, and briefly
display the firmware version, then enter
Measurement mode. When the meter is in
Measurement mode, and the button is
momentarily pressed and released, it will
display the species setting value. Press and
release the button again to return to
Measurement mode.
To turn Off the meter from Measurement
mode only, press the On/Off/Species
button for 3 seconds and then release. The
meter will also turn itself off automatically
when not in use as described in the autoshutdown section.

MMC 205 Instructions Continued. . .
Species Setting:
The species setting can be changed to
compensate for a variety of wood species.
When measuring another species other than
the factory default setting of 0.50 Specific
Gravity (SG), the species setting needs to
be changed. Refer to the Species Setting
Tables included with your meter to locate
the correct species setting for your wood.
If your species setting is not listed, refer to
the “Species Corrections” portion of this
manual. The values entered into the MMC205 meter omit the decimal point, so for
example the Douglas Fir value of 0.50 would
be “50” when programming the Species
Setting Value.
When the meter is in Measurement mode,
momentarily pressing and releasing the
On/Off/Species button will cause the display
to show the current specific gravity setting.
Press the button a second time for 3 seconds
8
and release to enter CHANGE SPECIES
MODE, or momentarily press and release
the button to return to Measurement mode.
When CHANGE SPECIES MODE has been
selected, a blinking colon symbol (:) will
appear on the display. Momentarily pressing
the On/Off/Species button again will
increment the selected specific gravity value
by 01. The value will go as high as 70, then
will wrap around to 30 and continue
incrementing. When the desired setting has
been reached, press button for 3 seconds and
release to store the value and return to
Measurement mode.
Your commonly used species setting values
can be written on the meter overlay decal in
the space provided using a pencil or nonpermanent marker, and erased with a swab
dipped in isopropyl alcohol. Avoid using a
permanent marker because staining of the
decal may occur.
