SECTION 6—TESTING PROCEDURES
6.3
6.4 TUNING FORK TESTING
Supplied with the Raptor RP-1 are two tuning forks, 35 and
65 mph. These tuning forks will simulate targets in the
stationary, moving opposite and moving same direction
modes.
The tuning fork tests should be conducted with the
antennas pointed away from traffic to avoid reflections
from moving vehicles.
** Due to the ability of the Raptor RP-1 to reject
non-directional signals, the operator must place the
unit in the FORK TEST mode to read tuning forks.
Momentarily depress the Test (√) switch. Upon
releasing this switch, the Raptor RP-1 will complete
the internal tests and enter the tuning FORK TEST
mode.
The unit will remain in this mode for 30 seconds,
indicated by the FORK TEST displayed in the
message area. Tuning fork tests may be performed
while in this mode. Changing to a new mode will
refresh the timeout to 30 seconds, allowing fork testing
in different modes without leaving the test mode.
Pressing the Test (√) switch again, while in the Test
mode, will terminate the Test mode.
