The operating instructions for the model BD-2100 are divided
into two sections. Section A is a step-by-step guide to the
different features and basic use of your moisture meter.
Section B contains information on how the meter is used for
testing different materials.
Please read the instructions carefully. If require additional
information, please contact Delmhorst for assistance.
SECTION A
BEFORE YOU BEGIN
BUTTON FUNCTIONS
! Read Button -This button reads the Percent Moisture
Content value (%MC), in the user-selected scale.
@ Calibration Check Button - This button checks the meter
calibration. It also displays the average of up to 100
readings; displays the highest stored reading; erases the
readings.
# Scale Button -This button sets the display scale to #1
(Wood), #2 (Plaster/Concrete reference scale), and #3
(Gypsum). It also acts as a scroll key,depending on the
function.
$ Set-Point Button -This button programs the set-point
value. A buzzer will alert you if the meter reads higher
than the selected value. It also acts as a scroll key,
depending on the function.
CHECK CALIBRATION
hPress the read button ! and calibration check button @
simultaneously.Meter is in calibration if it displays 12%
(+ or -.2). Make sure the pins are not in contact with anything
when checking the calibration.
If you check the calibration and the meter does not display
12% it is likely an indication of a low battery. If this occurs,
change the battery immediately. Continued use with a low
batterymay cause the meter to go out of calibration. If you
have a fresh batteryand the instrument still does not indicate
aproper calibration, return it to DELMHORST for service.
See Service for Your Meter section.
When the battery is removed and then reconnected, the
meter displays its software version for one second and then
turns itself off. After replacing the battery, you must reset
the meter as described in Resetting the Metersection.

INFORMATION ABOUT YOUR
READINGS
The meter will accumulate up to 100 readings. After all 100
readings are “stored” it will not add new readings until the
memory has been cleared. It will also continue to display the
average of all 100 readings as a reminder that the memory
is full.
hTo add a reading to the sum of all the previously stored
readings, release the read button
! within 2 seconds.
When taking and storing readings of a specific material, be
sure to “clear” the meter before moving on to the next scale
if you do not want to group all of the readings together.

SECTION B
PRACTICAL APPLICATIONS
TESTING WOOD
hSet the scale to #1 Wood
hAlign the contact pins
^ parallel to the grain and push
them into the wood to their full penetration, if possible.
hPress the read button
! .The meter displays the %MC for
two seconds.
If the displayed reading is above the set-point value the set-
point buzzer will sound. Also, one of the LEDs on the front
panel will light up as follows:
Wood Scale #1
Green -6% to 15% Yellow -15% to17% Red - > 17%
The LEDs are a visual aid to help quickly determine the
moisture level that each reading indicates. Readings that
activate the green light indicate a sufficiently dry moisture
level, those that activate the yellow light indicate a border-
line situation, and those that activate the red light indicate
material that is too wet for most appliations.
Delmhorst uses the USDA standard–Douglas Fir– as the
basis for all calibrations. Because the electrical characteristics
of different species vary, some species may read differently
at the same moisture content. However, in most cases, the
Douglas Fir reading can be taken at face value on construction-
grade lumber.If you choose to apply species corrections
please contact us at 877-DELMHORST or e-mail us at
[e-mail].
Paint Failure and Moisture
Moisture is by far the most frequent cause of paint failure.
The key to preventing paint failure is to make certain that
moisture is not absorbed through the wood to the back of
the paint film. So, in order to insure quality paint jobs,
wood must remain dry after the application of paint.
Outdoor wood can be safely painted without danger of
peeling if the %MC is 15% or less. In drier climates, the
maximum reading should be 10% to 11%. Indoor wood
should be between 7% to 8% prior to painting.
6

The following conditions may cause high moisture content
in wood:
hLeaky gutters and down spouts
hLeaky pipes or condensation on cold water lines in attic
or hollow walls
hFaulty flashing around windows, doors and where porch
and dormer roofs meet sidings
hEnd-grain wood that is not sealed with paint at all joints
around windows, corners, and butt joints
hPorch columns that do not have good drainage and
ventilation where they rest on porch floors
hSiding or any other wood that is in contact with the
ground
hSiding and shingles without sufficient lap so that water
is forced up through cracks by wind pressure
hIce dams
hCondensation of vapor within hollow walls
EIFS (Exterior Insulation & Finish Systems)*
Moisture intrusion problems in EIFS (also known as
synthetic stucco) stem from leaking window frames,
improper use of or lack of sealant, and faulty installation
of flashing.
If you suspect a problem take a visual inspection. Look for
gaps around windows, doors, air conditioning units, light
fixtures, hose bibs, dryer vents and other areas of potential
penetration. Also look for visible signs of water damage. If
you feel a problem exists, use the BD-2100 with a #21-E
electrode.This electrode includes the #608 - (4”) insulated
pins.
Procedure:
hDrill two 1/4” holes about 3/4” apart at an upward
45˚ angle.
hPush the #21-E Electrode into the holes through the
polystyrene and into the substrate.
hPress read button
! and read the moisture content
on the display.
*Refer to the wood scale #1 if the sheathing is plywood. If
gypsum sheathing is used, refer to the gypsum scale #3.
7

8
TESTING GYPSUM
hSet the scale for #3 Gypsum (measures gypsum %MC over
the range of 0.2% - 50%).
hTo take a reading, push the contact pins
^ into the gypsum
to their full penetration, if possible.
hPress the read button
! ,and read the moisture content on
the display. The meter displays the reading for 2 seconds.
The set-point buzzer will sound if the displayed reading is
above the set-point value. Also one of the LEDs on the front
panel will light up as follows:
Gypsum Scale #3
Green -0% to 0.5% Yellow -0.5 to 1% Red - > 1%
The LEDs are a visual aid to help quickly determine the
moisture level that each reading indicates. Readings that
activate the green light indicate a sufficiently dry moisture
level, those that activate the yellow light indicate a borderline
situation, and those that activate the red light indicate material
that is too wet for painting or wallpaper.
USING THE 0-100
REFERENCE SCALE
When taking a reading on hard materials such as concrete or
masonry,use Scale #2 to determine a qualitative reading.
Tests should be made on samples of material that are known
to be dry. Such readings can be used as standard or reference
points, against which subsequent readings are compared. All
readings should be evaluated in the light of factors such as
type of paint, type of construction, and climatic conditions.
The set-point buzzer will sound if the displayed reading is
above the set-point value. Also one of the LEDs on the front
panel will light up as follows:
0 -100 Reference Scale #2
Green -0-85 Yellow -85-95 Red - >95
The LEDs are a visual aid to help quickly determine the
moisture level that each reading indicates. Readings that
activate the green light indicate a sufficiently dry moisture
level, those that activate the yellow light indicate a border-
line situation, and those that activate the red light indicate
material that is too wet for most applications.

Testing Plaster Walls
Under normal drying conditions and proper application of plaster
(sufficient drying time between coats), surface readings give accurate
results. However, if rapid drying occurs, the surface of the plaster
may be dry, but moisture is still present below the surface and will
eventually affect the paint or wallpaper. This condition occurs when
there is high temperature or exceptionally good air circulation, or
where brown scratch and white coats are applied within a few
days.Take several readings on each wall. Pay special attention near
the base, around doorjambs, electrical and plumbing fixtures, and
other places where the plaster is thicker than normal.
Taking a Surface Reading:
hDrive the contact pins ^ into the plaster to their full
penetration, if possible.
hPress read button
! and read the reference scale.
Taking a Reading Below the Surface:
hDrive a pair of nails into the plaster at least 1/3 of the
total thickness of the plaster.If you are applying plaster
to a material of doubtful dryness, such as brick or con-
crete, drive the nails through the plaster and into the
brick or concrete.
hTouch the heads of the nails with the contact pins
^ and read
the meter.
Testing Concrete Slabs for Flooring
Applications
Moisture meters are an effective tool to check moisture in
concrete. They can tell you where there may be excess moisture
and help determine if you need to conduct further testing.
It is important to test both the surface and mid-section of the
slab, especially if the slab is on or below grade. This will help
determine if there is continuous moisture migration toward
the surface. If this condition exists, the moisture movement
may be so slow that once it reaches the surface, moisture
evaporates and causes a “dry” reading when a surface test
is made.
However, if a sub-surface test is made, the meter may read
“wet” indicating the presence of moisture. When the slab is
covered and the upward movement of moisture continues, moisture
will move into a hygroscopic (wood) floor,or build-up pressure
under a non-breathing synthetic floor, causing delamination.

Taking a Surface Reading:
hDrive 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.
hTouch the nails with the contact pins
^ .
hPress read button
! and read the reference scale. If
the meter reads in the red or “wet” area, it shows the
floor is not satisfactory for covering. If meter reads in
the green or “dry” area, the surface is dry. However,
subsurface tests should be made to verify if the slab is
dry throughout.
Subsurface Test:
hDrill two 1/4” holes, 3/4” apart and 1/2” to 2” deep.
hDrive the masonry nails into the bottom of the holes and
make the tests as described above. Nails must not touch
sides of drilled holes.
If the meter still indicates green or “dry” the floor is ready
for covering. Tests should be made at several points,
especiallywhen the slab is thick and air circulation is poor.
Tests should only be made in newly drilled holes, since the
inside surface of the holes can dry out while the rest of the
slab is still wet.
Even readings in the red or “wet” area can indicate
relatively low moisture content in concrete. For example,
readings in the 85-95 range on the reference scale indicate
approximately 2% to 4% moisture content.
If more testing is required, the calcium chloride test is
recommended, which measures the moisture vapor emission
rate of concrete. The National Wood Flooring Association
offers the following guidelines when evaluating the results
of the calcium chloride test***.

Key Factors to Consider:
hThe age of the slab. National Wood Flooring Association
guidelines specify to wait at least 30 days after the slab
is laid before checking moisture content. ***
hIs the slab on grade or suspended? If the slab is on
grade, is there an effective vapor barrier under the slab?
hHow thick is the slab?
hWhat is the drainage condition of the ground?
hHistory of other structures in the area
***Taken from Section V Appendix AA “Moisture Testing
Procedures for Concrete Slabs” — NWFA
Testing Brick or Concrete for Paint Application
Brick, stucco, or concrete surfaces must be dry at the time of
application and must remain dry after paint is applied or failure
of the paint film may occur. These materials are frequently
exposed to unusual moisture conditions that allow them to absorb
moisture through some exposed surface or some structural defect.
This is why it is important to check the moisture content of the
brick or concrete when it has been exposed to conditions that
permit it to absorb moisture.
Procedure:
hDrive two hardened steel masonrynails about 3/4” apart into
the brick or concrete. Drive them about 1/4” deep so they
make firmcontact and do not move when touched.
hTouch the nails with the contact pins
^ .
hPress read button
! and read the reference scale.
Normally,dryconcrete or brick will read in the green or “dry”
portion of scale, indicating a safe condition to apply paint.
Meter readings should be evaluated in relation to other factors —
knowledge of the structure, type of paint used, expected weather
conditions in the near future, etc. Paint should not be applied if
readings are in the red or “wet” portion of the scale.
Do not be misled by surface appearance of masonrymaterials.
Short exposure to rain may thoroughly wet the surface while
the interior is still dry. In this instance, we recommend repeating
the test on the masonry below the surface as mentioned above.
11

12
Key Areas to Check:
hThe rear side of brick parapet walls — generally are not
waterproof above the flashing line and frequently absorb
moisture during rains.
hPainted concrete floors on ground — subject to peeling as
they absorb moisture from the earth, unless an effective
vapor barrier has been installed.
Tests on these materials should be made a day or so after they
have been exposed to rain or other high moisture conditions
to verify to what extent they absorb moisture.
Tracing Leaks
The BD-2100 can help trace leaks in masonry material.
Normally, dry plaster, brick, or concrete will contain so little
moisture it cannot be detected by the meter. If the meter
indicates the presence of moisture you can trace the moisture
to its origin.
To trace the origin of a leak:
hDrive a nail into an area that is known to be wet and attach an
insulated wire between the nail and one of the contact pins
^ .
hApply the other pin to various parts of the wall where you suspect
the leak originates. If the meter indicates red or “wet”, the material
is wet between the points of contact. If the meter reads green or
“dry”, the material along this line is not in the path of a leak.
Toconfirm if a brick wall is waterproof:
Perform the following procedure after storms to verify if a brick wall
is waterproof, or if waterproofing repairs have been properly performed:
hDrive pairs of nails into the brick wherever it is necessary to
make the tests and leave them in place until after all the tests are
completed.
hTake readings after each storm, and record the readings. The
patternof these readings will indicate if the brick is gradually
drying out or is moistened again by each storm.
Detecting Moisture in Insulation
Use the BD series meter with the #21-E Electrode and #608
insulated pins to detect moisture in insulation. These pins are
insulated, except at the tips. Only the uninsulated tips make
contact with the material, providing information as to the
depth at which moisture is present.

Procedure:
hDrill two 3/16” diameter holes, one inch apart through
the siding.
hUsing the #21-E, insert the #608 contact pins into
the holes so that you make contact with the insulation.
hPress the read button
! and take a reading. Take read-
ings at various depths of penetration to determine the
location of moisture.
hFill holes with putty at the conclusion of the test.
Meters are not calibrated to read the percentage of moisture
content in the insulation. Instead, meter readings provide
aqualitative indication of the presence of moisture. The
meter may also help identify the pattern of distribution to
help you determine if moisture is due to condensation or
leakage.
The presence of moisture in insulating material greatly
reduces its insulating properties. If the insulating material
absorbs moisture, water will displace the air in the material.
Water also transmits heat at a faster rate than air,thus
reducing the efficiency of the insulation.
Side walls and roof insulation pick up moisture because
of leaks in the roof or structural defects in the side walls
which allow storm water to be forced in during high
wind. During periods of cold weather,vapor will condense
as it approaches the colder area near the outside walls,
and resulting moisture will remain trapped in the insulation.
Cork, wood fiber boards, and other cellulose material read
lower than glass wool and other inorganic types of insulation.
CARE OF YOUR METER
Tokeep your meter in good working order:
hStore your meter in a clean, dry place. The protective
carrying case provided is an ideal storage place when the
meter is not in use.
hChange the 9-Volt battery as needed. Continued use with a
low battery may cause the meter to go out of calibration.
hChange contact pins as needed. Keep pin retainers hand
tightened.
hClean the meter and contact pins with any biodegradable
cleaner. Use the cleaner sparingly and on external parts
only. Keep cleaner out of the external connector
& .
hRemove the battery if the meter will not be used for one
month or longer.
