No Thermal Image (Visible Light Only) AKA Color Alarm

Certain models have various apparent temperature color alarms.

This function can often lead to some confusion.

If you are showing no thermal image but you can see a visible light image you may have turned on your color alarms. 

The high temperature color alarm shows a full visible image and only shows infrared information on objects or areas that are above the set apparent temperature alarm level.

The low-temperature/dew point color alarm shows a full visible image and only shows infrared information on objects or areas that are below the set apparent temperature/dew point color alarm level.

The user must manually find and set these parameters. Certain models also display color isotherms, or infrared information, inside or outside of a set of both high and low limits.
