LTI TRUCAM LASER MEASUREMENT DEVICE - Tele-Traffic

Section 7 - Instrument Tests & Confidence Checks
Tele Traffic UK Ltd recommends the following tests be performed by an operator before or after
each shift to confirm proper instrument operation. The combination of operator-performed daily
checks and built-in instrument self tests provide positive indication of a system fault, should
one occur.
Self Test
When the TruCAM is powered ON, a number of internal checks are performed. During those tests all
display segments are lit and a series of tones are emitted.
When all of the tests have successfully completed, the Self Test Results Screen is displayed briefly
before the instrument is ready for use.
If any test fails, a system error message is displayed and the instrument will not operate. See page 17
for information about Self Test results.
HUD Integrity Test
Tele Traffic UK Ltd recommends that you perform this test before
or after each shift to verify that all in-scope display segments are
operating properly.
At power ON, compare the instrument’s in-scope Heads Up Display to
Figure 61. The lower portion of the display flashes 2 times and the aiming
reticule is illuminated. If the display times out before you can complete
this test, you will need to power OFF the TruCAM and repeat this step.
If any segment fails to display, contact Tele Traffic UK to arrange for repair.
See the inside front cover for Tele Traffic UK Ltd contact information.
Scope Alignment Test
Tele Traffic UK Ltd recommends that you perform this test before or after each shift to verify proper
alignment of the aiming reticule to the laser measurement beam.
Scope alignment is set at the factory when the instrument is shipped. A heavy blow is the only reason
that the aiming reticule might ever go out of alignment.
The Scope Alignment Test uses sound to indicate when the scope is on-target with the laser
measurement beam.

Figure 61
When the scope is properly aligned and you are targeting close targets, you may see a small vertical
offset due to the separation between the optics of the sighting scope and the laser transmitter.
Therefore, where possible when performing the Scope Alignment Test you should choose a target that
is at the longest distance available.
