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 alwa ys 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 specif ic 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 highlig hted on the screen. For purposes of this owner’s manual, the five keys will be referred to as     and SELECT.

Fig. 1 Keypad Layout

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.

Find Quality Products Online at: sales@GlobalTestSupply.com

www.GlobalTestSupply.com

Page 5 of 32

2. Ensure correct polarity, and push the battery in flush with the bottom board until the connectors snap together on both sides. Use only Duracell or Energizer alkaline 9V.

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. I F THIS OCCURS, CERTAIN FUNCTIONS (SUCH AS STAT ISTICS, 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) indicat or s 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.

METER USE

BASIC AND ENHANCED MODES:

TotalCheck 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, TotalCheck 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:

TotalCheck 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 t o 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  key to highlight PIN MODE. Then,

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 example, assume the selected job contains 23 readings. The View Set entry will begin by displaying “1 TO 23”. Successive Right button and “21 TO 23”. At this point, the value on the left side is within 10 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.

EXIT: This menu option returns the meter to Main Menu.

IR LINK:

This meter 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 Instrument Co.’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 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 TotalCheck and base unit are lined up and the base unit is connected to a USB port option in the Main Menu. The meter will display the message “Linking…” for a few seconds, followed by “Link OK” when successful communication is

(a green LED should be lit), select the IR LINK

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 manag ing 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 IR 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 k ey 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.

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.

TAKING A READING – PRACTICAL APPLICATIONS

The following application notes are intended for use with the meter in PIN MODE.

TESTING WOOD:

Use the 26-ES electrode on hard materials, wood over 2 inches thick, or for any application where using the insulated pins are needed for best accuracy. The 2-E electrode, with pins that penetrate 5/16” maximum are best for drywall and wood up to 2 inches. The 22-E with 1/2in non-insulated pins is also an excellent option for wood or drywall. Mount the electrode directly to the external connector at the top of the meter..

⇒ 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.

⇒ 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 reading s 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 t he 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:

⇒ 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 por ch 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 thr ough 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 potent ial penetration. Also look for visible signs of water damage. If you feel a problem exists, use the TotalCheck 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 k nown. 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 met er to REL 0-100 for a qualitative indication of the moisture level. Make the best use of reference scale by first establishing a benchmark for the mater ial 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 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 quantitative results as a basis f or acceptance of a slab for installation of moisture-sensitive flooring systems. ASTM Test Method F2170 (RH using in-situ probes), F1869 (calcium chloride), and F2420 (RH on surface using insulated hood) provide quantitative information for determining if moisture levels are within specif ic limit s .

It is important to test both the surface and mid-section of the slab, especially if t he slab is on or below grade. This will help determine if there is continuous moist ure 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” indicat ing 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 surface readings:

 Set the meter to PIN mode and the 0-100 Rel scale

Find Quality Products Online at: sales@GlobalTestSupply.com

www.GlobalTestSupply.com

Page 26 of 32

 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 contac t with the concrete and do not move when touch

 Touch the nails with the contact pins.  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.

Taking subsurface readings:

 Drill two 1/4" holes, 3/4" apart and 1/2" to 2" deep.  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. T ests

should be made at several points, especially when the slab is thick (4” or mor e) 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.

SCAN mode may also be used for comparative testing on smooth slab surfaces.

MEASURING RH IN CONCRETE SLABS:

TotalCheck can be used to measure the RH in a concrete slab in accordance with the ASTM F-2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs.

Basic Test Procedure:

⇒ Drill a 5/8” hole to a depth of 40% of the slab thckness using a rotary hammer

drill. Use a drill bit specially designed for rotary drills and with 3 or 4 cutting edges to insure a smooth, round hole. Surface preparation is not required.

⇒ Vacuum the hole thoroughly, then use a wire brush to clean and loosen any

concrete remaining in the hole. Vacuum again and repeat the process a second time.

⇒ Insert the yellow sleeve into the hole. Use silicone (or other water-resistant

sealant) to seal the interface between the collar of the sleeve and the concrete

surface. Use a hammer to insure the sleeve is fully inserted into the hole and sealed to the concrete.

⇒ Insert the protective yellow cap into the sleeve and let the hole acclimate for 72h.

Optional plugs (p/n CS-Plug) are available in three sizes that will isolate a 0.062 space at the hole bottom during acclimation time.

⇒ Remove t

he cap and immediately insert the RH probe sensor to full hole depth. Wait minimum 1h. Connect one end of the RH/T-C1 cable to the top of meter and the other end to the exposed end of the probe sensor. Take reading using the RH/TEMP mode of TotalCheck as described on pages 10 and 15.

⇒ Alternately, insert the RH probe sensor into the sleeve immediately after setting

the sleeve. Readings can then be taken as soon as the hole has acclimated. Note that continued and long term exposure to high humidity may damage the sensor irreversibly.

Refer to the White Paper, “Relative Humidity Sensor Behavior and Care” on our website for addi

tional information regarding the sensor itself.

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 drywall 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.

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.
