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 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.

5.3 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 color 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.
