OPERATING INSTRUCTIONS
-User Guide-
This guide provides step-by-step instructions on powering up, using and powering down the
meter.
NAVIGATION:
The meter uses an on-screen, menu-driven approach to navigate through the meter features,
allowing for an intuitive understanding of keypad functions. Each screen presents the user with a
number of selectable options. One of the options is always selected and the user can move
(navigate) the selection to any other available option. The keypad is aimed at providing
navigational control, and not at accessing specific features. There are four directional keys
aligned intuitively around a middle (fifth) key (see Figure 1): Above (UP), below (DOWN), to the
right (RIGHT) and to the left (LEFT). The middle key is used to SELECT the option highlighted on
the screen. For purposes of this owner’s manual, the five keys will be referred to as
ï ð ñ ò and SELECT.
INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom of the handle.
1. Open the battery compartment by sliding the lid back while pressing on the release indent.
2. Ensure correct polarity, and push the battery in flush with the bottom board until the
connectors snap together on both sides.
3. Replace the battery compartment lid.
LOW BATTERY:
The meter features a battery status monitor, designed to warn the user as well as protect
measurement accuracy from impending battery failure conditions. The battery warning is
triggered by either continuous or temporary low voltage conditions. Visible (a battery icon on the
top right side of the display) and audible (buzzer warble) indicators accompany a battery warning.
Once a permanent low battery condition is detected, all measurement functions are disabled. The
battery should be replaced immediately. If the battery reaches critical levels, the meter will refuse
to stay on at power-up. This gradual warning system is intended to provide the user advanced
battery status notice and give ample time for replacement before operational limitations occur.
NOTE: Current meter settings are not lost during battery replacement or low battery conditions.

Page 6of 33
3. Push the contact pins into material to be tested. Any Delmhorst electrode may also be
used in WOOD mode by simply attaching it to the connector next to the contact pins.
4. The unit will read %MC on a wood scale between 6% and 60%. At elevated wood
temperatures, a reading above 30 percent is valid if the temperature-corrected reading
falls below 30 percent. Otherwise, these high readings provide relative comparisons,
indicating that the material is taking on or losing moisture.
5. To hold a reading on-screen, press the HOLD (SELECT) KEY. Press the HOLD
(SELECT) KEY again to return to measuring mode.
6. Use the òkey to highlight EXIT. Then, use the SELECT key to return to the MAIN
MENU when finished.

TAKING A READING –PRACTICAL APPLICATIONS
The following application notes are intended for use with the meter in PIN
MODE except where otherwise indicated.
TESTING WOOD:
The contact pins provided are best for materials up to 6/4. On materials over 6/4 or for
hardwoods over 4/4 we recommend using a remote probe such as the 26-ES ram-type electrode.
Mount the 26-ES directly to the external connector. To take a reading, align the contact pins
parallel to the grain and push them to their full penetration into the wood, if possible. Insulated
pins read only at the tip and can be driven to the desired depth.
PAINT FAILURE AND MOISTURE
Moisture is by far the most frequent cause of paint failure. The key to preventing paint failure is to
insure 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% and
8% prior to painting.
The following conditions may cause high moisture content in wood:
⇒Leaky gutters and down spouts
⇒Leaky pipes or condensation on cold water lines in attic or hollow walls
⇒Faulty flashing around windows, doors and where porch and dormer roofs meet sidings
⇒End-grain wood that is not sealed with paint at all joints around windows, corners, and butt
joints
⇒Porch columns that do not have good drainage and ventilation where they rest on porch
floors
⇒Siding or any other wood that is in contact with the ground may absorb moisture
⇒Siding and shingles without sufficient lap so that water is forced up through cracks by wind
pressure
⇒Ice dams
⇒Condensation 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 21-E electrode.
This electrode uses the 608 -(4") insulated pins or 608/001 (7”) insulated pins.
Procedure:
⇒Drill two 1/4" holes about ¾” apart at an upward 45° angle.
⇒Push the 21-E Electrode into the holes through the polystyrene and into the substrate and
read the moisture content on the meter scale. When used on materials other than wood, the

Copyright 2009, Delmhorst Instrument Co.
Page 10 of 33
meter’s PIN mode will give relative readings only, not %MC. The numbers displayed
represent the relative dryness or wetness of the material on a scale of 5 to 60. In order to
accurately interpret your readings, first establish a baseline reading by taking a reading in an
area you know to be unaffected, then take a reading in the affected area and compare the
two readings.
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:
USING PIN MODE
ØDrive 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.
ØTouch the nails with the contact pins. Remember that when used on materials other
than wood, the meter’s PIN mode will give relative readings only. Establish a baseline
reading by taking a reading in an area you know to be unaffected, then take a reading in
the affected area and compare the two readings.
USING SCAN MODE
ØFirst establish a benchmark. Take readings in areas that you know are dry, or
acceptable.
ØTake readings on areas that are wet. These “dry to wet” readings can be used as
reference points against which subsequent readings are compared. Understanding the
meter’s behavior on a particular material, along with these comparative readings, your
experience, and visual clues will all help determine the overall condition. All readings
should be evaluated in the light of factors such as type of paint, type of construction, and
climatic conditions.
Subsurface test:
ØDrill two 1/4" holes, 3/4" apart and 1/2" to 2" deep.
ØDrive the masonry nails into the bottom of the holes and make the tests as described
above. Nails must not touch sides of drilled holes.

Copyright 2009, Delmhorst Instrument Co.
Page 11 of 33
If the meter still indicates a “dry” condition, the floor is ready for covering. Tests should
be made at several points, especially when the slab is thick (4” or more) and air
circulation is poor. Make tests only in newly drilled holes.
When evaluating a slab for readiness, always consider its age, thickness, whether the
slab is on grade or suspended, whether a vapor barrier is present and the drainage
condition of the ground.
TESTING INSULATION:
To take a reading, attach a 21-E electrode with 4” insulated contact pins to the meter. Push the
contact pins through the Drywall into the insulation behind it. Remember that when used on
materials other than wood, the meter’s PIN mode will give relative readings only. Establish a
baseline reading by taking a reading in an area you know to be unaffected, then take a reading in
the affected area and compare the two readings.
TESTING DRYWALL
USING PIN MODE
To take a reading, set the meter scale for drywall and push the contact pins into their full
penetration, if possible.
Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.
USING SCAN MODE
You can also take a reference reading on drywall using the meter’s SCAN mode. To take a
reading, firmly press the back of the meter onto the material to be tested while in SCAN mode.
This will display a relative reading that ranges between 0 and 300. Remember to establish a
baseline reading by taking a reading in an area you know to be unaffected, then take a reading in
the affected area and compare the two readings.

CARE OF YOUR METER
ØStore your meter in a clean, dry place. The protective carrying case provided is an ideal
storage place when the meter is not in use. If the meter has been left in a hot or cold
environment overnight or for an extended period, the calibration of the pinless mode may be
adversely affected. Under these conditions, allow the meter to acclimate to the temperature
conditions in which it will be used for minimum 1-2 hours, or as long as possible.
ØChange contact pins as needed. Keep pin retainers hand tightened.
ØClean 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.
ØRemove the battery if the meter will not to be used for one month or longer.

INSTRUCCIONES DE FUNCIONAMIENTO
-Guía del usuario-
Esta guía proporciona instrucciones paso a paso para encender, usar y apagar el medidor de
humedad.
NAVEGACIÓN:
El medidor de humedad usa una pantalla con menús para navegar por las funciones del medidor,
permitiendo el entendimiento intuitivo de las funciones del teclado. Cada pantalla presenta al
usuario una serie de opciones seleccionables. Una de las opciones está siempre seleccionada y
el usuario puede mover (navegar) la selección a otra opción disponible. El teclado es para dar
control de navegación y no para acceder a funciones específicas. Hay cuatro teclas direccionales
alineadas intuitivamente alrededor de una tecla central (quinta) (véase la Figura 1): Encima
(ARRIBA), debajo (ABAJO), a la derecha (DERECHA) y a la izquierda (IZQUIERDA). La tecla del
centro se usa para SELECCIONAR la opción resaltada en la pantalla. En relación con este
manual del propietario, llamaremos a estas cinco teclas ï ð ñ ò?y SELECCIONAR.
INSTALACIÓN DE LA BATERÍA:
El compartimiento de la batería está ubicado en la parte inferior de la caja, al final del asa.
1. Abra el compartimiento de la batería deslizando la tapa hacia atrás mientras presiona en la
muesca de liberación.
2. Asegure que la polaridad sea la correcta y empuje la batería de manera que pegue con la
tarjeta del fondo hasta que los conectores se enganchen a ambos lados.
3. Vuelva a colocar la tapa del compartimiento de la batería.
BATERÍA BAJA:
El medidor de humedad presenta un monitor de estado de la batería, diseñado para advertir al
usuario y también para proteger la precisión de la medición contra las condiciones de fallo
inminente de la batería. La advertencia de la batería la accionan las condiciones continuas o
temporales de bajo voltaje. Los indicadores visible (un icono de batería en la parte superior
derecha de la pantalla) y sonoro (zumbador) acompañan a la advertencia de la batería.
Una vez que se detecta una condición de batería baja permanente, se desactivan todas las
funciones de medición. Habrá que reemplazar la batería inmediatamente. Si la batería alcanza
niveles críticos, el medidor de humedad se apagará al encendido. Este sistema de advertencia
gradual tiene la intención de dar al usuario aviso avanzado del estado de la batería y darle
