3 Save data Save the information after analysis.
4 Rendering type
There are 14 types of rendering. The default setting is White Hot.
White Hot: Brighter when temperature is higher in gray image.
Black Hot: Brighter when temperature is lower in gray image.
Fusion: Colors fall within purple-red-yellow range. Purpler when
temperature is lower, and yellower when temperature is higher.
The following content will take Fusion as an example.
Rainbow: Colors fall within blue-green-red-yellow range. Bluer
when temperature is lower, and yellower when temperature is
higher.
Globow: Colors fall within red-
yellow range. Redder when
temperature is lower, and yellower when temperature is higher.
Ironbow1: Colors fall within blue-purple-red-yellow range. Bluer
when temperature is lower, and yellower when temperature is
higher.
Ironbow2: Color range is similar to Ironbow1, but its brightness
is lower than Ironbow1
Sepia: Mainly brown. Brighter when temperature is higher.
Color1: Colors fall within purple-red-yellow-green-
blue range.
Purpler when temperature is lower, and bluer when temperature
is higher.
Color2: Colors fall within blue-red-yellow range
. Bluer when
