3. Introduction
Thank you for selecting the FLIR MR176 Imaging Moisture Meter. The MR176 integrates high quality thermal imaging technology with the best in class moisture detection and measurement. The MR176 includes an integrated non invasive pinless moisture sensor, an external pin moisture probe (MR02), and a replaceable temperature and relative humidity sensor (MR01) that provides dew point, vapor pressure, and mixing ratio readings in addition to air temperature and relative humidity.
Featuring Infrared Guided Measurement (IGMTM) technology, the MR176 helps to quickly scan and target moisture issues; visually guiding the user to the spot where measurements can be confidently made and where readings can be easily analyzed. The MR176 can save measurements and images for later transfer to a PC; reports can be generated with FLIR Tools PC software. Please see www.flir.com/test for additional accessories available for this device. This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
Please register the FLIR MR176 within 60 days of purchase for extended warranty at the following location: www.flir.com/testwarranty

5. Operation
Important Note: Please charge the meter’s battery before first use. Instructions for battery charging are provided in Section 6.2.
5.1Powering the Meter
1.Press the Power button
momentarily to switch the meter ON.
2.Press and hold the Power button for > 1 second to switch the meter OFF.
3.If the battery status indicator shows that the battery voltage is low, or if the meter does not power on, charge the battery. See section 6.2 Battery Charging. The battery status indicator is visible in the Main Menu (press the center Select button to access the Main Menu).
4.Please fully charge the battery before use.
5.1.1Auto Power OFF (APO)
The meter switches OFF automatically after a programmed period of inactivity. Press any button to reset the APO timer. To disable APO, or to change the APO time out value, use the
Settings
mode, accessible from the Main Menu. The default time out is 20 minutes.
5.2Moisture Measurements
5.2.1Moisture 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 19mm (0.75”). 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 (0~100). 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.
