6.4.1 STATIONARY TUNING FORK TEST
1. Place the Raptor RP-1 in the stationary “STA ALL”
mode of operation.
2. Momentarily press the Test (√) switch to enter the Fork
Test mode. The message area will display FORK
TEST.
3. Lightly strike the lower speed tuning fork on a hard,
nonmetallic surface. Place the fork in front of the
antenna. Make sure the antenna to be tested is active,
(not in HOLD). Verify a target speed display of the
value stamped on the tuning fork, +1 mph (+1 km/h).
5. Repeat for the higher speed tuning fork.
NOTE: Since the Raptor RP-1 can determine these fork
signals are non-moving targets, the speeds
displayed during the fork tests cannot be
LOCKED.
