Two (2) TEMPERATURE INDICATORS are provided in the display screen.

– The BAR GRAPH and DIGITAL readout at the right side of the display report

the temperature of the small Target Area in the center of the display screen.

– The MAX Temp in the upper left corner of the display appears reports the

highest temperature in the entire screen display.

Positioning the Temperature Target Area over an object seen in the display

will register an approximate temperature of that object on the Bar Graph and

Digital Temperature Readouts.

The EAGLE IMAGER 320 Thermal Camera display operates in two tempera-

ture ranges:

1) Low Range up to approximately 230° F /110° C, and

2) High Range or EI Range from 230° F /110° C to 1200° F / 650° C.

When the display is in the Low Range, greater resolution makes small tem-

perature differences more obvious. This range is useful for identifying non-re

sources of heat.

When the display is in the High Range or EI Range, the EI (Electronic Iris) sym-

bol appears in the upper left corner of the display. This wider range is useful for

identifying elevated heat sources that could be potential locations of re.

The camera selects the range for the display screen based on the highest

temperature detected as a percentage of the entire display. When enough of

the sensor “sees” a high enough temperature, the display screen will shift to

the High or EI Range.

There may be occasions when the sensor detects a temperature in a small

percentage of the display that exceeds the Low Range, but there is not enough

of that temperature to shift the display to the High or EI Range. When this hap-

pens at the Temperature Target Area, the Bar Graph Temperature Readout will

reach the top and the Digital Temperature Readout will say, “HOT” instead of

a number value. The EI Indicator has not yet appeared. The MAX Temp in the

upper left of the display will still give a number value for the highest temperature

detected in the entire screen display. See FIGURE 17.
