Manufacturer’s Recommended Daily Test
In keeping with NHTSA (National Highway Traffic Safety
Administration) and IADLEST (The International Association of
Directors of Law Enforcement Standards and Training) guidelines
general operational considerations for LIDAR Speed Measurement
devices, the operator must perform the following accuracy checks prior
to beginning enforcement operations:
1) Internal Circuit Check
2) LED Segment Test
3) Range (Chronometer) Accuracy Test
4) Horizontal Sight Alignment Test
5) Vertical Sight Alignment Test
WHAT THE DAILY TEST ACCOMPLISHES:
To ensure that the SpeedLaser
®
is in good working order, the
SpeedLaser
®
should be tested using the Manufacture’s daily test
described later in this chapter. This test restores the factory default
settings, checks the LIDAR hardware (including the program and
dynamic memories), tests the displays and timing circuits, and then
allows the operator to verify that the HUD aiming crosshairs are
correctly aligned with the laser beam.
NOTE: The alignment crosshairs in the HUD are set at the factory and
generally do not need realignment over the life of the SpeedLaser
®
.
1) Internal Circuit Check
When the operator presses Menu followed by Test (button A on the
keypad), the SpeedLaser
®
runs a BIT (Built-In-Test) program. The
BIT program tests the hardware and verifies that the SpeedLaser
®
firmware is loaded correctly. It then checks that the processor is
executing the data gathering, storing (memory), sorting, filtering,
conversion and linear regression algorithms correctly.
2) LED Segment Test
This test allows the operator to verify that the seven-segment display,
used to show speed of the target vehicle, is in good working order by
displaying a simple known pattern. The operator can then confirm
that each segment operates correctly.
