5.2.6 External Moisture Probe (Pin) 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).
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 %WME) in the upper left hand
corner (IR + Moisture mode) or as a bargraph with accompanying digits (Moisture ‐ only
mode). Refer to example screens shown in Fig. 5 ‐ 1 and Fig. 5 ‐ 2.
5.2.7 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 a new display line will appear preceded by a
delta (triangle) symbol. The digits next to the triangle symbol indicate the reference value
(the measurement recorded when the SET REFERENCE mode is selected). Refer to
example screens shown in Fig. 5 ‐ 1 and Fig. 5 ‐ 2.
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. The reference value is displayed on the main display in the upper left hand corner (IR +
Moisture mode) or to the right of the bargraph (Moisture ‐ only mode). Refer to example
screens shown in Fig. 5 ‐ 1 and Fig. 5 ‐ 2.
5. 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.
