Introduction
Congratulations!
You have purchased one of the most accurate moisture measurement instruments for wood in the world.
Using patented electromagnetic wave technology, hand-held moisture meters from W agner Meters have
been proven by universities and institutes worldwide to provide superior measurement results.
With its electro-magnetic field, your Wagner moisture meter covers 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 only m e a su re a very sma ll area, and on ly at a particu lar
depth, giving you very limited insight into the true moisture content of the wood. Very short, noninsulated pins are especially p ro n e to ju st r ea d ing th e su rfa c e o f y o u r wood. Wagner moisture me te rs re a d
IN the wood, not just on the wood.
The 11/2 inch wide by 21/2 inch long by 3/4 inch thick sensing area of your Wagner moisture m e ter closely
approximates the full-th ic kn e ss cross-section method used when performing the ASTM D 4 442-92 ovendry lab method. This ASTM standard (and its international counterparts) is the standard to which all
moisture meters for wood are compared for accuracy.
The Wagner Meters 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, an d
are ideal for anyone who needs a professional quality tool to inspect wood or 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 hand-held moisture meters from Wagner Meters include:
• The "Wood-Friendly"™ MMC 200 series meters use advanced electromagnetic wave technology
to accu rate ly measure wood moisture co nte nt
1
to a depth of 3/4 inch. The MMC 205 c an read
values from 5% to 20%, w hile the MM C 210 can read 5% to 30%. The MMC 220 can read 5%
to 30% at settings up to .80 SG. Note: If the MMC 220 species s ettin g 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.2
Since 1966, Wagner Meters has been providing quality moisture measurement equipment. Wagner Meters
is the leading supplier of moisture measurement equipment for the primary forest products industry.
Wagner Meters’ technology has been proven to provide some of the most accurate results in the industry
when compared to this worldwide standard. Closely scrutinized and approved by numerous university
studies and use d for years by professional lumber-grading associations, moisture meters from Wagner
Meters continue to provide reliable and consistent moisture measurements, with unsurpassed convenience
and ease-of-use.

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, an d the button is mom entarily 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 u se as described in the autoshutdown section.
Species Setting:
The species setting can be changed to compensate for a variety of wood species. When measuring another
species with a Spe cific Gravity (SG ) other than the factory default setting of 0.50 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, contact Wagner Meters. The values
entered into the MMC 205 meter omit the decimal point, so for example the Douglas Fir value of 0.48
would be “48” 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 displ ay to show the current specific gravity setting. Press the button a second time for 3
seconds and release to enter C HA NG E SPECIES MODE, or momentarily press a n d 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 O n/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 be en reached, press button for 3 seconds and re lea se to store
the value and return to Me a su re m e n t mode.
Your comm only used species setting values can be written on the meter overlay decal in the space
provided using a pencil or non-permanent marker, and erased with a swab dipped in isopropyl alcohol.
Avoid using a permanent marker because staining of the decal may occur.

Taking Measurements
In order to tak e correct moisture con tent measurements,
ensure that the meter’s
specific gravity (species) setting is the right on e for your species of wood as listed
in the Species Setting Tab les .
3
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 tak e rea dings where there is a noticeable defect or
knot in the lumber.
If there is visible surface moisture or water, w ipe 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 th ickn ess of the piece is greater than 1
1
/2 inches, it is a good idea to take measurements on both
sides.
If the lu m be r thickness is less than the scan depth of the m e ter, an air gap of at least one inch needs to be
maintained underneath the wood to prevent erroneous high readings. Ensure that there is nothing
(including your hand) u nd er the material you are meas uring , especially any metal. The actual moisture
sensing area is a 1
1
/2 inch b y 2 1/2 inch rectangle on the m ete r’s backside (opposite side of the display
and keypad). In order to take a valid measurement, this sensing area must be completely covered with the
wood or other material 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 treate d with C CA, ACQ or any other tr ea tment with metallic or other components that might bia s
the moisture readings.
