• ECB - LIGHTNING DETECT SYS (R AFT Bus)
(11)
Make sure that no self-test failure messages appear.
(12) Stormscope is now powered up and initialized.
(a) Make sure that no self-test failure messages appear.
(13) Make sure “LIGHTNING FAIL” annunciation on the GPS 400W extinguishes 10-20
seconds after ECB - LIGHTNING DETECT SYS (R AFT Bus) is RESET.
NOTE: The left Garmin display will annunciate “TEST” in the upper right corner for
10-20 seconds after the “LIGHTNING FAIL” annunciation extinguishes,
indicating that the Stormscope computer is in self-test. The “TEST”
annunciation will then change to “RATE”, unless a Stormscope self-test
failure occurs. If a selftest failure occurs during initialization, determine the
nature of the test failure prior to continuing with this test procedure.
B. Initial System Test
(1)
On the left Garmin 400W, select the 360° display mode (if not already in 360° mode).
Verify proper 360° display format on the left Garmin 400W unit.
(a) If not already in 360° mode, on left Garmin 400W:
1 Press MENU button.
2 Use outer knob (lower right corner) to scroll down to “View 360?”.
3 Press the ENT button.
(2)
On left Garmin 400W, select STRIKE mode (if not already in STRIKE mode). Verify
STRIKE MODE is displayed on the left Garmin 400W Lightning display format.
(a) If not already in STRIKE mode, on left Garmin 400W:
1 Press MENU button.
2 Use outer knob (lower right corner) to scroll down to “Strike Mode?”.
3 Press the ENT button.
(3)
On left Garmin 400W, set range to 100 NM (if not already set to 100 NM).
NOTE: Outer ring; inner ring will say “50 nm”.
(a) If not already set to 100 NM, on left Garmin 400W:
1 Press RNG button on right end (▲) to increase range.
2 Press RNG button on left end (▼) to decrease range.
(4)
Make sure Strike RATE counter is displayed in STRIKE mode.
NOTE: Strike RATE counter should be displaying 0, unless there is real
thunderstorm activity within detection range (nearby man-made electrical
noise such as a blower motor or electric drill can also cause strike data to
appear). If so, the test strike data in the following steps will be displayed
along with real storm strike data (or man-made electrical strike data).
(5) Tune the VHF 1 COMM radio to a test frequency.
