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 SELECT and ï ð ñ ò.

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.
IMPORTANT NOTE:
DO NOT REMOVE THE BATTERY WITHOUT TURNING THE METER OFF FIRST. BATTERY REMOVAL WHILE THE METER IS ON MAY CAUSE LOSS OF STORED READINGS AND MAY CORRUPT THE STORAGE MEMORY. IF THIS OCCURS, CERTAIN FUNCTIONS (SUCH AS STATISTICS, READING RECALL, ETC) WILL FAIL AND LOCK UP THE METER. If the battery is removed by accident while the meter is ON, and if the readings already stored are important, DO NOT store additional readings. Turn the meter back on and perform a PC download. Beware that any readings stored during the power cycle that included the battery removal WILL NOT be available and CANNOT be recovered. Once the download is complete, perform a meter reset by choosing “RESTORE DEFAULTS” in the Storage Menu. If a download is not necessary, go directly to “RESTORE DEFAULTS”.
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. Enough power remains for other menu functions, including a PC download, although almost any user action at this time causes a low-battery warning to be generated. 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: Stored readings are not lost during battery replacement or low battery conditions. Current meter settings are maintained as well.

The next screen is the MAIN MENU. Use ï ð ñ ò keys to select the desired function/mode and then press SELECT to activate the function.
METER USE
BASIC AND ENHANCED MODES:
MoistureCheck may be used as a BASIC meter, which allows the user to begin taking readings
in either the scan mode or pin mode, without having to set up a job definition. BASIC mode does not allow for data collection and is the default mode of the meter upon power up.
Or, MoistureCheck may be used in ENHANCED mode, which requires the user to set job definitions and materials for each location within a job. The meter also stores each reading in
ENHANCED mode to allow for on screen reading recall or download to a PC.
USING THE METER IN BASIC MODE:
MoistureCheck is shipped from the factory set to BASIC mode. Use this option if you wish to use the meter for scan or pin readings without having to set up a job.
Although Basic Mode does not allow for data acquisition, it does allow the user to set the type of material being tested, and set the alarm to sound if a pre-established %MC is exceeded.
TO TAKE PIN READINGS IN BASIC MODE:
1. From the BASIC Main Menu, use the ò key to highlight PIN MODE. Then, use the
SELECT key to enter the pin mode.
2. The meter will display the main %MC READ screen, as shown below:

1. While in the main menu, use the arrow keys to highlight option #3 STORAGE
2. Press the SELECT key to enter the storage sub menu. There are four available
selections in this menu shown below.
View Statistics:
o This menu option selects the meter’s statistical analysis option. Selecting this option gives the user access to two sets of statistical data. A screen shot example of the first set is shown below:
Copyright 2005, Delmhorst Instrument Co.
Page 15 of 29
o The first line indicates the Moisture Content (MC) job being analyzed. o The second line shows the number of readings stored in the specific job o The third line shows the Average MC value for all stored readings in the specific job. o The fourth line shows the Standard Deviation for the specific job. o The fifth line shows the Coefficient of Variation for the specific job. o Selecting “MORE” gives the user access to the second set of statistical data. o Selecting “DONE” returns the user to the storage menu screen.
NOTE:
The second set of calculations may require significant processing time, depending on the number of readings stored in the specific job. The meter will display a screen with the word “PROCESSING…” while calculations take place. User input is ignored during this time. Control is returned to the user once the algorithm is complete and the second statistics screen is shown, as in the example below:
o The first line indicates the specific MC job. o The second line indicates the number of readings present in the specific job. o The third line shows the 95% Confidence Interval for the specific job. This is the value
(+/-) away from the calculated average value within which 95% of the stored readings are guaranteed to exist.
o The fourth line shows the value of the lowest MC reading stored in the specific job. o The fifth line shows the value of the highest MC reading stored in the specific job.
There are no control entries present in this screen, such as “MORE”, “CANCEL” or “DONE”. The only available option is to return to the storage menu screen, by pressing any key.
Stored Readings:
1. From the storage sub menu, use the keys to highlight “STORED READINGS.”
Press the SELECT key to enter the stored readings sub menu.
Copyright 2005, Delmhorst Instrument Co.
Page 16 of 29
2. By using the ï ?ð keys you may select which job you wish to view. If there are no readings in a job, the following screen will display:
If there are readings saved to a job, the following screen will display:
After you have made your job selection, scroll to DONE and press the SELECT key.
A complete record of information per reading will be displayed. You will be able to scroll through each reading, using the NEXT key. Scroll to “DONE” if you do not wish to see any more readings.
A selected job containing readings offers two other selectable options: “VIEW SET” and “DONE”.
o VIEW SET: This option allows the user to view a specific range of readings in a
particular job, as opposed to the entire set, by providing a configurable start point. It becomes useful when large numbers of readings are present in the meter. View Set always begins by displaying “1 TO XXX”, where XXX is the maximum number of readings in the selected job. If left unchanged, the first reading to be reviewed will be number 1. Readings may only be reviewed in ascending sequential order.
Using the ï ?ð keys, the left-side value can be changed in increments of 10. For example, assume the selected job contains 23 readings. The View Set entry will begin by displaying “1 TO 23”. Successive Right button presses will yield the following: “11 TO 23” and “21 TO 23”. At this point, the value on the left side is within 10 readings of the value
Copyright 2005, Delmhorst Instrument Co.
Page 17 of 29
on the right side. Alternately, pressing the Left button causes the meter to subtract 10 from the current left-side value.
o DONE: Selecting this option signals to the meter that the user has completed the reading
recall setup process and is ready to begin reviewing readings.
NOTE: There may be a significant delay while the meter processes the required set of readings for review, depending on the number of jobs present in the meter, percentage of memory space occupied by readings, current job size and fragmentation. The meter will display a screen with the word “PROCESSING…”. User input is ignored during this time. Control is returned to the user once the algorithm is complete and the Retrieved Readings screen is displayed, as shown in the example above:
Cancel: This feature returns the meter to the Storage Menu
CLEAR MEMORY:
This option will delete all the readings stored in the meter, but will keep the defined job structures in tact.
§ RESTORE DEFAULTS:
This will delete all defined parameters and readings stored in the meter. The meter will be now set to the factory parameters: T = 70F, Non-insulated probe, Backlight = OFF, Power-off time = 2 min.
Note: Memory deletion and restoring defaults are both irreversible.
§ EXIT:
This menu option returns the meter to Main Menu.
IR LINK:
This menu option initiates a wireless communication session during which the currently stored readings will be downloaded to a PC. Before using this feature, the target PC must be loaded with Delmhorst’s Universal Application Program and a Delmhorst base unit must be connected to an available USB port.
Requirements:
The wireless communication technology employed in the meter requires line-of-sight access between the red side window of the meter and the receiving window of the Base Unit. Simply place the meter and Base Unit on a flat surface, with the red side window of the meter facing the
Copyright 2005, Delmhorst Instrument Co.
Page 18 of 29
receiving window of the Base Unit. Separation requirements between the meter and Base Unit are anywhere from 0 to 12 inches.
Operation:
1. Begin by starting the Delmhorst Instrument Co. Universal Application Program
(double click the application icon or choose the program from the Start Menu).
2. Once the MoistureCheck and base unit are lined up and the base unit is connected
to a USB port (a green LED should be lit), select the IR LINK option in the Main Menu. The meter will display the message “Linking…” for a few seconds, followed by “Link OK” when successful communication is established with the base unit. The base unit will also indicate communication established by turning off the green LED and turning on a red LED.
3. Press the “MANAGE DATA” button in the Delmhorst Instrument Co. Universal
Application Program. The meter will display “Data” on the screen and the base unit will alternately turn on a yellow and red LED while data transfer takes place (red indicates communication between the meter and Base Unit, while yellow indicates communication between the base unit and the PC). When finished, the meter will return to the Main Menu and the base unit will, once again, turn on its green LED. For further details on managing the meter data in the PC please refer to the HELP feature in the program.
NOTE: The above sequence of events in initiating communication between the PC and the meter is not mandatory. The Application Program may be started first, or the IR Link may be selected first. The MANAGE DATA button may also be pressed before communication is started between the Base Unit and the meter. The meter, base unit and Application Program all have ample delays built in to allow the other link components to come online in any sequence.
Troubleshooting The I/R Link:
Most problems tend to occur due to the positioning of the meter relative to the base unit. There are a few error messages that may appear on the meter’s screen:
a. Timeout: This error message occurs when too much time has passed between data
sent by the meter and the response that should have been received from the base unit. Possible causes:
Meter misalignment with the Base Unit (make sure the communication windows are facing each other, within the distance indicated).
No connection to the PC. The Base Unit must be connected to the PC through a USB cable. Check connection.
b. KBD: This message occurs when the user presses a key during communications. Do not push any key on the meter during data transfer. The meter interprets this as a request to escape this activity and returns to the Main Menu. The base unit should return to a green LED status in a few seconds. A message should appear on the PC screen as well, indicating lost communications.
Copyright 2005, Delmhorst Instrument Co.
Page 19 of 29
c. Sync: This message occurs when data framing is lost during data transmission. This
would only happen if the wireless link becomes unreliable. Ensure the meter and base unit are aligned and restart the session.
d. Data E: This message occurs when the content of a correctly framed data packet is
invalid. Again, this is an unreliable wireless link problem.
NOTE: Individual records cannot be downloaded to the PC. The entire storage content is delivered to the PC during a link session
SETUP MENU:
The Setup group of features allows access to the configurable parameters of the meter. They are: Date and Time, Power-off time, Backlight, and Conversions (temperature mode and electrode type). All can only be accessed in the Setup Menu. To get to the Setup Menu, use the ñ ò
keys to highlight option #5: SETUP.
SETUP MENU ENTRY DESCRIPTIONS:
o Return to Main Menu: This menu option returns the meter to Main Menu. The meter
also returns to Main Menu if no user input is detected for 20 Seconds.
o Set Date and Time: This menu option allows user access to the date and time set
screen:
The Date and Time set screen is populated with the time and date values present in the meter at access time. UP and DOWN key action switches the row selection among available parameters. LEFT and RIGHT key action changes the selected parameter’s value (for “DONE” and “CANCEL” – parameters without assigned values, the LEFT and RIGHT keys perform no function). All parameter values are incremented using the RIGHT key and decremented using the LEFT key. The DAY parameter moves forward through weekdays using the RIGHT key and backward using the LEFT key. The SELECT (center) key is only active when menu selection is applied to “HOURS” (switch between standard or military time), “DONE” or “CANCEL”. Selecting “DONE” exits this screen back to the SETUP MENU and updates the clock with the newly chosen values. Selecting “CANCEL” exits this screen back to the SETUP MENU without updating the clock.
Copyright 2005, Delmhorst Instrument Co.
Page 20 of 29
o Set Power_Off time: This menu option allows the user to change the amount of time
allowed to lapse between the last key press and meter shut-down. Allowable range is 1min – 9min, with a default value of 2min.
o Set Backlight: This menu option allows the user to change the amount of time allowed to
lapse between the last key press and backlight shutdown. The default setting for this feature is “NO”, where the backlight is completely disabled. Backlight shutdown delays are 10, 20, 30sec. It is recommended that the backlight delay be set to the minimum amount of time necessary in order to maximize battery life.
o Conversions: This menu option allows the user to change the temperature scale from
Fahrenheit (default) to Celsius. You can also change the electrode type from 4-pin (or default non-insulated) to 2-pin (or insulated).
NOTE: Except for clock settings, all other parameters will return to their default values, as indicated above, when the “RESTORE DEFAULTS” option is selected in the Storage Menu. The values chosen for the Setup Menu parameters will remain in effect even if the meter is turned off, and even if the battery is removed.
TAKING A READING – PRACTICAL APPLICATIONS
The following application notes are intended for use with the meter in PIN MODE.
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.
Set the meter’s parameters as described previously in the owners’ manual. If the species
(construction-grade only) is unknown, set the meter to the reference calibration, Douglas Fir and take the readings at face value.
Copyright 2005, Delmhorst Instrument Co.
Page 21 of 29
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.
Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.
To add a reading to the previously stored readings, release the SELECT button if you are in
triggered mode. If you are in continuous mode, the meter will not store a new reading until the SELECT button is pressed and released again during the reading cycle.
NOTE: MC RANGE AND VALID READINGS
Readings below 5% or above 60% are displayed as LOW or HIGH, respectively. However, since the resistance of the wood also depends on the species and temperature of the wood, the meter may not always be able to read down to 5%. For different species and different wood temperatures, there is a minimum %MC limit below that the meter can not read. All readings below this “lowest limit” are displayed as LOW, and are not stored. These readings are not considered valid readings and are not used by the meter in any statistical calculations.
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

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 Moisture Check with a # 21-E electrode. This electrode includes the #608 - (4") insulated pins or #608/001 (6”)
Insulated pins in EIFS Package.
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. ⇒ Press the SELECT button and read the moisture content on the meter scale. The meter
displays the %MC for two seconds.
To add a reading to the previously stored readings, release the SELECT button if you are in
triggered mode. If you are in continuous mode, the meter will not store a new reading until the SELECT button is pressed and released again during the reading cycle.
*If the sheathing is plywood, set the meter to the proper species if known. If the species is unknown, use Douglas Fir. If the sheathing is gypsum material, set the species to Drywall.
USING 0-100 NUMERICAL REFERENCE SCALE (REL 0-100)
When taking a reading on hard materials such as concrete or masonry, set the meter to REL 0­100 for a qualitative indication of the moisture level. Make the best use of reference scale by first establishing a benchmark for the material you are testing. Take readings in areas that you know are dry, or acceptable. Then take 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.
The user-selectable alarm will sound if the displayed reading is above the alarm value.
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:
Drive 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.
Ø Touch the nails with the contact pins. Ø Press The select key and read the meter. If the meter reads less than “68”, the surface
is dry. However, sub-surface tests should be made to verify if the slab is dry throughout.
Subsurface test:
Ø Drill two 1/4" holes, 3/4" apart and 1/2" to 2" deep. Ø Drive 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 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.
Even readings in the “wet” range can indicate relatively low moisture content in Concrete. For example, readings in the “68 to 77” range indicate approximately 2% to 4% moisture content.
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:
Set the meter scale for the “REL 0-100” as described in the Create/Edit a Job section on
page 12.
To take a reading, attach a 21-E electrode with 4” insulated contact pins to the meter. Push
the contact pins through the Sheetrock® into the insulation behind it.
Press the SELECT button and read the moisture content on the meter scale. The meter
displays the “relative” moisture level for two seconds.
To add a reading to the previously stored readings, release the SELECT button if you are in
triggered mode. If you are in continuous mode, the meter will not store a new reading until the SELECT button is pressed and released again during the reading cycle.
TESTING DRYWALL
Set the meter scale for Sheetrock® as described in the Create/Edit a Job section on page
12.
To take a reading, push the contact pins into the Sheetrock® to 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.
To add a reading to the previously stored readings, release the SELECT button if you are in
triggered mode. If you are in continuous mode, the meter will not store a new reading until the SELECT button is pressed and released again during the reading cycle.
Note:
Readings between 0.1% and 0.5% indicate a sufficiently dry moisture level. Readings between 0.5% and 1% indicate a borderline situation. Readings greater than 1% indicate material that is too wet for painting or wallpaper. A reading above 1% also indicates enough moisture present to allow mold growth to occur but only if other factors are also present such as a high RH level and food source.

CARE OF YOUR METER
Ø Store 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.
Ø Change contact pins as needed. Keep pin retainers hand tightened. Ø Clean 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.
Remove the battery if the meter will not to be used for one month or longer.
