BEFORE YOU BEGIN

The BD-10 features two scales — one marked

“wood” and the other marked “reference”. The

wood scale #is used to measure moisture content

of wood materials over the range of 6% to 40% MC.

The reference scale $provides relative (wet/dry)

readings over a 0-100 range when measuring

moisture levels in building materials such as

plaster, concrete, brick, insulation, IFS, etc.

These 0-100 readings are NOT indications of

%MC. Readings in the low end of the scale indicate

a “drier” condition; readings in the upper end of

the scale indicate a higher moisture level in the

material. The scale is color coded with green,

yellow, and red areas. Readings may be interpret-

ed as green (dry), yellow (borderline), red (wet).

When using the reference scale $, tests should be

made on material samples that are known to be

dry. Such readings can be used as standards or

reference points against which subsequent readings

should be compared.

CHECK CALIBRATION

hPress the calibration check button @. The meter is in cali-

bration if the needle pointer moves to “20” on the wood

scale #. Any reading within the green band on the dial is

acceptable. Make sure the contact pins %are not in con-

tact with anything when checking the calibration.

If you check the calibration and the needle does not read

within the green band, it is likely an indication of a low bat-

tery. If this occurs, change the battery with a Duracell or

verReady 9V immediately. Continued use with a low battery

may cause the meter to go out of calibration. If you have a

fresh battery and the instrument still does not indicate a

proper calibration, return it to D LMHORST for service.

See Service for Your Meter section for details.

TAKING A READING

hRemove the protective cover to expose the pins. Check

that the contact pins %are firmly hand tightened.

TESTING WOOD

hAlign contact pins %parallel to the grain pushing to

their full penetration, if possible. If using an external

electrode, attach it to the connector ^and also align

the pins parallel to the grain before driving them

into the wood.

hPress the read key !and read the %MC on the wood

meter scale #.

The color-coded scale is a visual aid to help quickly deter-

mine the moisture level that each reading indicates. Use it as

a guideline. Readings in the "green" indicate a sufficiently dry

moisture level, those in the "yellow" indicate a borderline sit-

uation, and those in the "red" indicate that the material is too

wet for most applications. specific applications may require

different MC thresholds.

If your application requires a higher level of accuracy (ex.

finish flooring, furniture-making) Delmhorst recommends

applying the following corrections:

hTemperature – As wood temperature increases, its

electrical resistance decreases and indicated moisture

content rises. Lower wood temperatures result in lower

indicated moisture content. If the wood temperature,

which is typically the ambient temperature, is between

50°F/10°C and 90°F/32°C, there is no need to apply a

correction. Refer to the temperature correction table at

the end of the manual.

hPin (insulated vs non-insulated) – The reference

calibration of the meter was made with non-insulated

pins that penetrate 5/16 inch. Insulated pins read slightly

lower than noninsulated ones. When using an electrode

with insulated pins, such as the 26- S, refer to the

correction at the end of the manual.

hSpecies – Delmhorst uses Douglas Fir, the USDA

standard, as the basis for all wood calibrations. Because

the electrical characteristics of different species vary, all

species read differently at the same moisture content. For

this reason, a species correction is required. Refer to the

species correction table at the end of the manual.

P int F ilure nd 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. 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.

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

hnd-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 Insul tion & Finish Systems)*

Moisture intrusion problems in IFS (also know 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-10 with a #21-

electrode. This electrode includes the #608 insulated pins

that penetrate 3-1/4". Also available - #608-001 insulated

pins with 6" penetration.

Procedure:

hUsing a drill or the available HP-1 hole punch, make 2

(1/4") holes about 3/4" apart at an upward 45˚ angle.

hPush the #21- lectrode into the holes through the

polystyrene and into the substrate.

hPress read key !and read the moisture content.

*Refer to the wood scale #if the sheathing is plywood.

If gypsum sheathing is used, refer to the reference

scale $.

USING THE 0-100 REFERENCE SCALE

Testing Concrete Sl bs for Flooring

Applic tions

Moisture meters are an effective tool to check comparative

moisture conditions in concrete slabs. They can tell you where

there may be excess moisture and help determine if you need

to conduct further testing, and identify specific areas on

which that testing should be performed. Meters do not

provide quantitave results as a basis for acceptance of a

slab for installation of moisture-sensitive flooring systems.

ASTM Test Method F2170 (RH using in situ probes), F1869

(calcium chloride) provide quantitative information for

determining if moisture levels are within specific limits.

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 resilient floor,

causing floor failure.

T king Surf ce Re ding:

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 %.

If the meter still indicates green or “dry” the floor is ready

for covering. Tests should be made at several points,

especially when 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.

ven 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.

Note: Perform minimum three tests for the first 1000 sq ft

and at least one additional test for each additional

1000 sq ft.

Select test locations to provide information about moisture

distribution across the entire concrete slab, especially

areas of potential high moisture, or if the slab is thick

(>4 in) and air circulation is poor. For slabs on-grade and

below-grade, include a test location within 3 ft of each

exterior wall.

Key F ctors to Consider:

hThe age of the slab. Wait at least 30 days after the slab

is laid before checking moisture content.

hPress read key !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.

Subsurf ce 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.

hHistory of other structures in the area

Testing Brick or Concrete for P int Applic tion

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 masonry nails about 3/4” apart into

the brick or concrete. Drive them about 1/4” deep so they

make firm contact and do not move when touched.

hTouch the nails with the contact pins %.

hPress read key !and read the 0-100 reference scale $.

Normally, dry concrete 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 masonry materials.

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.

Key Are s 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.
