Forward-Looking Speed calibration
Per Vehicle Speed
Per vehicle speed measurements is required for Forward-Looking mode speed calibration. Ensure
that the main screen box Per Vehicle Speed is check-marked while performing forward-looking
speed calibration. Click this box to suppress transmission of per vehicle data, if desired, after
completion of speed calibration.

completion of speed calibration.
The Forward-Looking Highway mode uses the averaged, per vehicle Doppler speed, as the
reference speed to calibrate the length of the speed trap to assure accuracy of “trap” speed
measurements at low speeds (below 15 Km/h).
Automatic speed calibration is included in the Wizard automated zone setup for the Forward-
Looking mode. It may also be independently initiated.
When SPEED CALIB is selected, a choice of
Automatic or Manual calibration is presented:
⇒ Select the required mode of calibration
In Automatic calibration, the recommended number of
cycles is 10 (at 30 sec. Period). The Doppler reference
speed and % deviation of the average speed from the
reference are updated at the end of each Message
Period. When deviation is less than 10%, exit the
program.
In Manual calibration the zone length coefficient must
be adjusted up or down (range 150 to 500)
⇒ Click LOAD and wait to get acceptable deviation
