Environmental

Operating

10% to 80% relative humidity (RH), with 26 °C maximum

 

dew point.

Storage

5% to 95% relative humidity ambient with 33 °C (91 °F)

 

maximum dew point.

Maximum vibration

 

Operating

0.26 Grms at 5 Hz to 350 Hz (all operation orientations).

Storage

1.87 Grms at 10 Hz to 500 Hz for 15 min (all six sides

and negative x, y, and z axes (one pulse on each side of

 

the system) of 71 G for up to 2 ms.

 

Six consecutively executed shock pulses in the positive

 

and negative x, y, and z axes (one pulse on each side of

 

the system) of 22 G faired square wave pulse with

 

velocity change at 200 inches/second (508 centimeters/

 

second).
