Description
NOTE
The instrument meets all o f the following MIL-T-28800B require
ments for Class 5 equipment.
Temperature
Operating
0°C to +50°C (+32°F to +122°F).
Nonoperating
—55°C to +75°C (—67°F to +167°F).
Altitude
Operating
To 4,500 m (15,000 ft). Maximum operating temperature decreased 1°C per
300 m (1,000 ft) above 1,500 m (5,000 ft).
Nonoperating
To 15,000 m (50,000 ft).
Humidity (Operating and Nonoperating)
5 cycles (120 hours) referenced to MIL-T-28800B, Class 5 instruments.
Vibration (Operating)
15 minutes along each of 3 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
1-minute sweeps. Hold for 10 minutes at 55 Hz. All major resonances must be
above 55 Hz.
Shock (Operating and Nonoperating)
30 g, half-sine, 11-ms duration; 3 shocks per axis each direction, for a total of
18 shocks.
