Sensors
The TruSpeed has two lenses on the front panel. The top lens transmits the
infrared laser signals. The bottom lens receives signals back from the target and
feeds signal information to the internal circuitry.
The internal circuitry consists of a laser range sensor and timing, analysis,
computation, and display circuits. The TruSpeed determines distance through its
laser range sensor, by measuring the time of flight of short pulses of infrared light.
The TruSpeed has a broad spectrum of sensitivity, and can work with both
reflective and non-reflective targets. The maximum measurement distance varies
with target and environmental conditions. The absolute maximum is about 2,000
feet.
LCD Screen
The LCD Screen displays menu items, option indicators, error codes, and speed
measurement results.
Test Port
Your TruSpeed includes a Test Port located on the rear panel. The Test Port allows
you to connect the instrument to a remote computer for laboratory testing
purposes only.
Sighting Scope
Mounted on top of the TruSpeed is a single-power sighting scope. The scope
features:
• The polarizing light filter is adjustable to
optimize viewing contrast. Figure #2 shows
the polarizing light filter's adjustment ring.
• In-scope speed measurement display.
• The in-scope aiming reticle helps you aim
accurately to the target. Figure #3 shows
reticle. This reticle represents the size of the
laser beam.
L
You can vary the intensity of the aiming
reticle to account for different lighting
conditions. For more information, see page 13.
