Isotherm Modes: Micron/A10 provides a Isotherm capability in which sufficiently hot objects
are colored either yellow or red on the displayed image. Figure 25 shows an example image
with isotherms enabled. The figure shows a light shade along the perimeter of the square to be
yellow and the darker shade on the interior is red. Two Isotherm modes are provided:
1. Off. In Isotherm Off mode, isotherms are disabled and imagery is displayed strictly in
monochrome.
2. On. In Isotherm On mode, isotherms are enabled, and input windows for specifying
upper and lower threshold values are enabled on the Control Panel. The upper threshold
values specifies the temperature above which objects are displayed in red and the lower
threshold specifies the temperature above which objects are displayed in yellow. (The
yellow threshold must be less than the red threshold or no objects will be displayed in
yellow.) Both the upper and lower limits are expressed as percentages, ranging from 0%
to 100%. In low-temperature state the threshold represents a percentage of 150
o
F), and in high-temperature state, the threshold represents a percentage of 500
o
F). For example, assuming an upper threshold value of 90, then in low-temperature
state, objects with apparent temperature greater than 135
displayed in red while in high-temperature state, objects with apparent temperature
greater than 450
