ALIBRATION
Default = 250 pulses/300ft
The speed sensor needs to be calibrated in order
to provide the proper speed reading. The value
for this step is the number of pulses generated by
the speed sensor in 300 feet.
Auto Calibration
The speed sensor can be automatically calibrated
by driving 300ft. The console will automatically
detect a RADAR sensor (if used).
To start the auto calibration procedure, press
simultaneously on the
+
and keys. The
display now will show CAL.
Now you have to drive to the starting point of the
300ft distance. Push the
+
key to start counting
speed pulses as you cross the start point.
Drive 300ft and press
+
again to stop the pulse
counting as you cross the finish point.
Note: During Auto Calibration the Man LED will flash
each time a pulse is recorded.
The number now on the display is the number of
pulses corresponding to 300ft.
The auto calibration procedure can be escaped with
the key. The console will then return to the
previous calibration value.
Note: The auto speed calibration should be
repeated at least twice and an average of
the calibration numbers should be entered.
