9.4 Stationary Mode Test
1. Place the radar unit in Stationary Mode. (If you are using
directional antennas, be sure to select the Both Directions
Stationary mode. There are no directional properties to a ringing
tuning fork. If a stationary tuning fork test is done in either the
approach or recede modes, the radar will generally ignore the
tuning f or k . )
2. Select maximum range and activate the antenna to be tested.
3. Grasp the low speed tuning fork (the longer fork) by the handle.
Then tap the tines against a firm, non-metallic surface, and hold
the vibrating fork approximately three inches in front of the
antenna.
4. Verify that the TARGET display and speed marked on the tuning
fork are within ± 1 display unit of each other.
5. If desired, repeat the test with the high-speed tuning fork (the
shorter fork).
