Moisture Measurement Operation

2. Connect the supplied MR02 pin probe, or other external pin probe, to the

meter’s RJ jack at the bottom of the meter (under the protective flap). Re-

fer to https://www.flir.com for available moisture probes.

3. Select the appropriate Material Group in the menu system (Moisture

mode/Material) as described in Section 7.4 Moisture Measurement

modes. Also, See Section 15 Appendices for information on Material

Groups and the associated Group numbers to choose from in the menu.

4. Press the pins into the material under test.

5. Pin-based readings are represented in %MC (moisture content) for wood

and %WME (wood moisture equivalent) for materials other than wood.

6. The moisture reading is displayed on the main display (%) in the upper left

hand corner (Thermal and Digital Camera images) or as large digits (Mois-

ture-only mode). Use the menu to select the Image mode (Image mode

NOTE

Pin Probe Moisture Measurement Considerations

The MR277 will display accurate external pin probe readings in the 7% to 30% range, de-

pending 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 rel-

ative reference value.

For more information on fiber saturation please refer to public document ASTM D7438.

For additional information on Pin moisture measurement accuracy please refer to public

document ASTM D4444, section 6.

7.7 MR12 Ball Moisture Probe (Optional)

The MR12 allows you to take pinless moisture measurements with all the ben-

efits of a remote probe, i.e. easier access to surfaces and manoeuvrability.

1. Connect the MR12 to the RJ jack at the bottom of the meter.

2. Select the MR12 probe option in the menu (Moisture Mode/MR12); see

Figure 7–12 above.

3. Touch the MR12 probe to the surface under test.

4. View the moisture reading on the MR277 in either the Moisture-only dis-

play mode or the Thermal/Visible camera modes. Use the menus to select

the display modes (Image Modes).

5. Pinless measurement readings are ‘relative’ scaled (0~100).
