per 1000 feet above 5,000 feet.
5 cycles (120 hours) referenced toMIL-T 28800D para 4.5.5.1.2.2 for type III, Class
5 instruments.
To meet EMI regulations and specifications, use the specified shielded cable and
metal connector housing with the housing grounded to the cable shield on the
Parallel Printer/Plotter connector.
Test performed with probe containing 500 pF capacitor with 1 kn resistance
charged to the test voltage.
15 minutes along each of three major axes at a total displacement of 0.015 inch p-
p (2.4 g at 55 Hz) with frequency varied from 10 Hz to 55 Hz to 10 Hz in one
minutes sweeps. Hold for 10 minutes at 55 Hz in each of the three major axes. All
major resonances must be above 55 Hz.
8
30 g, half-sine, 11 ms duration, three shocks per axis each direction, for a total of
18 shocks.
• Edge lifted four inches and allowed to free fall onto a solid wooden bench
surface.
