7.3 IGM™ Moisture and IGM™ Custom Modes
In the IGM™ Moisture mode
you can view a camera image with the
Moisture reading appearing on the upper left. Select this mode in the menu
(Measurement/IGM™ Moisture). IGM™ stands for ‘Infrared Guided Measure-
ments’. The Pin or Pinless display icon will appear next to the reading. To take
full advantage of this feature, scan for temperature variations, and use this
feedback to help you find areas of high moisture. For additional information
see Section 5.5 Measurement modes.

In the IGM™ Custom mode , the same benefits apply to the discussion
above for IGM™ Moisture mode with the added benefits of displaying Air
Temperature, Relative Humidity, Vapor Pressure, Mixing Ratio, and Dew Point
Temperature on the camera image. To select which of these parameters to
display, use the Settings menu, Section 5.8, (Settings/IGM™ Custom).
For additional information see Section 5.5 Measurement modes.
