Setting Transmission Correction
When conducting infrared inspections through infrared-transparent windows
(IR Windows / Sightglasses), not all of the infrared energy emitted from the
objects of interest are efficiently transmitted through the optic material in the
window. If the transmission rate of the window is known, you can adjust the
transmission correction setting in the Imager or in SmartView
®
software.
Adjustment of the transmission correction setting may improve temperature
measurement accuracy.

Setting Temperature Alarms
The Imager has the ability to set a temperature alarm function. The Ti32, Ti29,
and Ti27 have a high-temperature alarm that allows the Imager to display a full
visible light image and only shows infrared information on objects or areas
that are above the set alarm level. The TiR32, TiR29, and TiR27 have a
dewpoint temperature alarm that allows the Imager to display a full visible
light image and only show infrared information on objects or areas that are
below the set dewpoint alarm level.
