Moisture measurements
With the meter in Moisture mode, moisture measurements can be performed us-

The internal moisture sensor can detect moisture to a depth of 19 mm (0.75″).
The internal moisture reading can be relative or absolute.
The three-digit main display shows the moisture reading, and the four-digit sec-
ondary display shows the ambient air temperature. The bar graph matches the
reading on the main display.
While in Moisture mode, IR measurements may also be performed, see section
5.4
