Moisture Measurements

Moisture Measurement Overview
Moisture measurements can be performed using either the internal pinless moisture sensor (rear) or by connecting an external probe. A standard external pin probe is included which connects to the MR176 via the jack at the bottom of the meter. Other external probes are available; please visit www.flir.com/test for details.

NOTE: Objects in close proximity to the internal pinless moisture sensor (located on the rear of the unit) will affect the reading on the display; Keep hands and fingers clear of the sensor when taking measurements.

The internal moisture sensor detects moisture to a depth of approximately 19 mm (0.75 in.). The actual depth will vary depending upon the amount of moisture, the material under test, surface roughness, and other factors. Moisture readings are shown on the display (digitally and with bar graph) in the Moisture-only mode or in small digits (upper left-hand corner) in the IGM Custom and IGM Moisture modes. See Fig. 5-1. Pinless measurement readings are ‘relative’ scaled (0 to 100). Pin-based readings are represented in terms of %MC (moisture content) for wood and %WME (wood moisture equivalent) for non- wood materials; additional information is provided in Section 5.2.6 External Pin Probe Moisture Measurements and in the specifications. Moisture measurements are covered in detail in the following sections. Be sure to select Pin Mode or Pinless Mode in the Moisture Menu to match the measurement type.

   Select a Material wood group that best matches the material under test. This applies only for external pin-based probe use; Use the navigation buttons to scroll through the group list and use the Select button to choose the group. The selected group will show a blue dot. See the Material Wood Group List Appendix in Section 9.

3. PIN MODE
   PIN mode must be selected when the external pin-based probe is used. Note the pin icon (3) on the upper left of the main display when selected.

4. PINLESS MODE
   PINLESS mode must be selected when using the internal sensor. Note the pinless icon (4) on the upper left of the main display when selected.

5. SET REFERENCE MODE
   SET REFERENCE is used to compare the displayed readings against a stored reference measurement (see Section 5.2.7 Reference Mode). This mode applies only to readings taken with the pinless internal sensor.

Internal Moisture Sensor Measurements (Pinless)

1. Follow the steps in Section 5.2.1 through 5.2.4 and select the Pinless mode.
2. Place the internal moisture sensor (back) on the surface of the material to be tested. Apply light pressure to ensure that the internal sensor is completely flat against the surface of the material under test.
3. The relative moisture reading is displayed on the main display in the upper left-hand corner (IGM Custom or IGM Moisture modes) or as bar graph with accompanying digits (Moisture-only mode). Refer to example screens shown in Fig. 5-1.
4. Keep hands, surfaces, and objects away from the rear internal moisture sensor area when taking measurements.
5. For best results, lift the meter from the surface under test between measurement points; do not drag the meter over surfaces.

External Pin Probe Moisture Measurements

1. Follow the steps in Section 5.2.1 through 5.2.4 and select Pin mode from the MOISTURE mode options.
2. Connect the external pin probe to the meter’s EXT jack on the bottom of the meter (under the protective flap). Refer to the FLIR website for information on available external pin moisture probe types.
3. Select the appropriate Material Group as described in Section 5.2.4 (see Section 9 for the Material Group Appendices). Note: Use Group 9 for building materials.
4. Press the pins into the material under test.
5. The moisture reading is displayed on the main display (%) in the upper left-hand corner (IGM Custom or IGM Moisture modes) or as a bar graph with accompanying digits (Moisture-only mode). Refer to example screens shown in Fig. 5-1.

Notes on External Pin Probe Moisture measurements
The MR176 will display accurate external pin probe readings in the 7% to 30% range, depending on the tested material. Moisture Content readings below 6% will display as 0% for all materials and the maximum specified range is dependent on the fiber saturation point for specific species. Above the fiber saturation point, the reading can only be used as a relative reference value. For more information on fiber saturation please refer to ASTM D7438. For additional information on Pin moisture measurement accuracy please see ASTM D4444, section 6.

Reference Mode Moisture Measurements

1. Follow the steps in Section 5.2.1 through 5.2.4 and select SET REFERENCE from the MOISTURE mode options. This mode is only available for pinless measurements (internal sensor).
2. When the SET REFERENCE mode is selected the displays are affected in the following ways:
   • IGM Moisture image mode: A new display line will appear preceded by a delta (triangle) symbol. The digits next to the delta symbol indicate the reference value (the measurement recorded when the SET REFERENCE mode is selected).
   • IGM Custom image mode: Only the delta icon is shown in the IGM Custom screen, not the reference value.
   • Moisture-only mode: The Reference value and delta symbol are shown on the right side of the display, refer to example screen in Fig. 5-1(c).
3. All measurements taken subsequently will be relative to the reference value. For example, if the reference value is ‘10’ (representing the driest area of the material under test) and a measurement of ‘50’ is taken (in an area with higher moisture content), the measurement line will show ‘40’ (50 – 10 = 40). As implied, this mode is useful for comparing wet areas to a dry area reference.
4. To remove the reference value and exit the mode: Remove the meter sensor from the area under test, so that the sensor is no longer touching a surface and is clear of any objects (keep hands away from the sensor also), and then press the Set Reference icon again. The reference value will no longer be visible on the meter display.

Thermal Imager (IR)
The full-screen IR Thermal Imager is active in the IR-only mode, the IGM Custom mode, and the IGM Moisture mode (selectable from the IMAGE mode icon in the Main Menu). The Thermal Imager lens is located on the back of the meter. Face the lens toward the area of interest and view the image on the meter display. Select the IR thermal image display colour palette from the Settings menu. Select IRON, RAINBOW, ICE, or GRAYSCALE; see examples in Fig. 5-5.

For example: the ICE palette hot to cold temperatures, for images, are represented by this color palette progression: white>grey>black>blue>white. See the color palette example below in figure 5-5(c). For the ICE palette, the right side of the scale shows the hotter pixels in the frame, and the left side of the scale shows the coldest pixels.

When the Laser Pointer button is pressed, and held to activate the laser pointer, the display crosshairs also switch on, for additional targeting flexibility. Refer to Fig. 5-6. Note that the laser is carefully aimed to align with the crosshairs for easier identifying and targeting of objects and surfaces.

Lock/Unlock Palette Auto-Scale Mode

Note: For best results, allow a warm-up period of 3-5 minutes before using this feature. The Lock/Unlock Palette Auto-Scale option allows the color palette range to be adjusted to suit a given application. For example, when viewing both cold and hot objects in the same frame, the palette auto-scaling will cause the palette to be ‘stretched’ to fit the whole range of temperatures. However, this can cause smaller temperature variations to disappear, as the difference between two colors might increase from 1° to 10°. In this case, the user may choose to lock the scale with only the cold or medium-temperature object in the frame. This would cause the hot object to saturate but will provide more detail to the colder objects of interest .

If the user wishes to narrow the range of color and limit it to colors near the cold temperature image, Lock/Unlock can be set to ‘Lock’ with no hot objects in the frame. To lock the scale, press the Select button to access the Main Menu, scroll to the Lock icon, and press Select again to toggle unlock/lock. Some experimentation and fine-tuning may be required to get the best possible contrast for the application.

Screen Capture and Hold
Pressing the Image Capture button captures the current MR176 screen. The screen will hold (freeze) for seven (7) seconds, until an image filename appears indicating that the image has been saved. During the seven second ‘hold’ period, the user can simply examine the image and press the Back button to discard or press Select/Capture to save the image. Images are saved in bitmap (.bmp) format. Images can be accessed on the MR176 screen using the Image Review icon available in the Main Menu. Then scroll the images using the Left and Right navigation buttons. Images can be deleted one by one by pressing the Select button while viewing the image. A prompt will appear asking to ‘Delete’ or ‘Cancel’. Choose ‘Delete’ to permanently discard the image; choose ‘Cancel’ to keep the image. Images can also be transferred to computer or other compatible device using the MR176 USB port (bottom of meter, under flap) and supplied USB cable.

Progressive Environmental Stability Indicator
The Progressive Environmental Stability Indicator is useful for determining when relative humidity readings on the MR176 have stabilized. This feature is especially useful when a series of readings is taken in a variety of locations with diverse environmental conditions. The circle next to the RH% display line (shown in Fig. 5-8) fills and turns green when the relative humidity reading stabilizes. For Fig. 5-8, line 1, the indicator is hollow indicating that the reading has not stabilized; line 2 indicates that the reading is stabilizing; line 3 indicates that the reading has fully stabilized (green circle with green relative humidity reading digits). Note that for areas where environmental conditions change frequently, the indicator may not fill and turn green, this is normal. The indicator is available in the IGM Custom, IGM Moisture, and Psychrometric modes.

Combination’ Feature: Save Thermal Image with Pinless Moisture Reading
The Combination feature allows the user to ‘freeze’ a thermal image and take a moisture reading, saving both the thermal image and the moisture reading on a single image. The ‘held’ thermal image, with continuous moisture reading shown on the same screen, can then be captured as explained in Section 5.5 above.

1. Enter the IGM Moisture or IGM Custom Image mode (refer to Section 5.2.3 Image Mode).
2. Hold the Capture button until crosshairs appear, and laser are visible (Fig. 5-9(a)).
3. While continuing to hold the Capture button, aim the laser at the measurement spot
4. Release the Capture button. The image will freeze but the moisture reading will flash and continue to update as it waits for a measurement.
5. Make the desired measurement and press the Select button to capture (save) the image; note that the image will include the moisture reading; see Fig. 5-9(b).
6. After a seven second hold period, an image filename will appear on the screen (FLIRxxxx.bmp), indicating the image has been saved. During this time-out period, the user can press Back to cancel the image capture or Select/Capture to save the image.
