3 Getting Started
The thermal imaging camera inside the PathFindIR LE is completely
sealed and extremely rugged. The camera has been qualified for operation
in all types of weather conditions over the specified operating temperature
range and includes an automatic window heater that will prevent icing
under most conditions.
3.1 Using your PathFindIR LE
The PathFindIR LE is easy to use, but you should take a moment to
carefully read this section so you fully understand what you are seeing on
your display. While the imagery you will see on the monitor may look like
black and white daylight video, it isn’t! A few tips on how to interpret some
of the imagery will help you to make the most of your system.
The camera automatically adjusts to changing scene conditions so no
additional camera control is necessary. Scenes with familiar objects will be
easy to interpret with some experience. The camera automatically
optimizes the image to provide you with the best contrast in most
conditions.
The thermal imager inside the camera does not sense light like
conventional cameras; it senses heat or temperature differences. As you
experiment with the system during nighttime operation, you will notice
variances in the “picture quality”; this is normal. The camera senses small
“differences” in apparent radiation from the objects in view, and displays
them as either white (or lighter shades of gray) for warmer objects, and
black (or darker shades of gray) for colder objects.
3.2 Initial System Startup
The PathFindIR LE camera requires power and a connection to an external
monitor to provide imagery. Make sure to test the system prior to
installation to assure the system is functioning properly. Be sure to remove
the protective window sticker prior to test and installation.
Upon initial power up you will hear a slight clicking sound. This click is
the internal image correction. This noise is the mechanical shutter
assembly which will cause the image to momentarily “freeze.” This noise
and image freezing will occur until the unit has reached a thermally stable
