GENERAL DESCRIPTION/FEATURES Thank you for your purchase of Delmhorst Instrument’s Navigator Pro handheld moisture meter / thermo-hygrometer. Navigator Pro has been developed specifically with the restoration contractor in mind. It provides the user with a host of data acquisition capabilities, and offers the latest in features and functionality. Even with its wide range of functions, Navigator Pro is intuitive and easy to operate.
OPERATING INSTRUCTIONS -User GuideThis 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.
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.
TO POWER THE METER ON: To turn the meter on, press and hold the SELECT button for approx. 2 seconds. The first screen will temporarily display the meter name and the software revision level. Refer to this revision level whenever you call Customer Service. The next screen is the MAIN MENU. Use keys to select the desired function/mode and then press SELECT to activate the function.

You may begin taking readings by inserting the pins into the material and pressing the SELECT key. This will display a %MC reading.
TO CHANGE THE TEMPERATURE CORRECTION: Navigator Pro defaults to a temperature of 70ºF. As wood temperature increases, its electrical resistance decreases and indicated moisture content rises. Lower wood temperatures result in lower indicated moisture content. A correction is necessary if the wood temperature is outside the range of 50ºF (10ºC) to 90ºF (32ºC). Set the temperature accordingly and the meter will make the correction. 1.
2. You may begin taking readings by firmly pressing the back of the meter onto the material. This will display a relative reading that ranges between 0 and 300. If you wish to hold a reading on screen, press the SELECT key; otherwise move the meter to another area to take continued readings. TO SET THE ALARM IN BASIC SCAN MODE: 1. If you wish to set the alarm to beep after a pre-selected relative value is reached, use the keys from the SCAN screen to highlight the ALARM.

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 Instrument Co’s Universal Application Program and a Delmhorst base unit must be connected to an available USB port.
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.

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.
TAKING A READING – PRACTICAL APPLICATIONS The following application notes are intended for use with the meter in PIN MODE. TESTING WOOD: 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.
TESTING CONCRETE SLABS: Moisture meters are an effective tool to check comparative moisture conditions in concrete. 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 for acceptance of a slab for installation of moisturesensitive flooring systems.
MEASURING RH IN CONCRETE SLABS IN ACCORDANCE WITH ASTM F2170: Navigator Pro can be used to measure the RH in a concrete slab in accordance with the ASTM F2170 Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs. Basic Test Procedure: Drill 5/8-inch hole in concrete to the appropriate depth and remove debris from the holes. Insert a CS-2 concrete sleeve into the hole and plug the sleeve with the cap that is provided with each sleeve. Wait approximately 72 hours.
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 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 pin less 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.
