DIRECTIONAL MOVING-VEHICLE TEST
A directional moving vehicle test can be performed as an additional check of performance and accuracy. To perform the moving
vehicle test: press the PWR key to turn on the radar. Use the MOV/STA key to switch into Stationary mode. (Note: This test cannot
be performed with VSS activated.)
TO TEST THE FRONT ANTENNA:
While driving a patrol vehicle, with an accurately calibrated speedometer, aim the front antenna down an empty highway directly in
front of the vehicle. While driving forward, alternately switch between the front OPP target zone and the front SAME target zone.
As you alternate between the two target zones, verify that the front OPP target zone always shows an accurate ground speed in the
target window while the front SAME target zone always shows no speed in the target window. While in front OPP target zone, the
moving roadway appears as an approaching target to the radar and will be seen in the front target window but will not be seen when
the radar is in the stationary front SAME target zone.
TO TEST THE REAR ANTENNA:
While driving a patrol vehicle, with an accurately calibrated speedometer, aim the rear antenna down an empty highway out the rear
window of the vehicle. While driving forward, alternately switch between the rear OPP target zone and the rear SAME target zone.
As you alternate between the two target zones, verify that the rear OPP target zone always shows an accurate ground speed in the
target window while the rear SAME target zone always shows no speed in the target window. While in rear OPP target zone, the
moving roadway appears as a receding target to the radar and will be seen in the target window but will not be seen when the radar is
in the stationary away rear SAME target zone.
The speed indicated by S
DSR 2X should match the speedometer indication within a small error (depending on speedometer
accuracy). This simple test verifies both accurate speed measurement and proper direction sensing operation.
This test is optional and is not a substitute for the tuning fork test, but is a good overall indication of proper operation of the unit.
