Altitude Test
Operation:10,000 ft
Non-Operation:30,000 ft
Note 1
: The TFT-LCD module will not sustain damage after being subjected to 100 cycles of rapid
temperature change. A cycle of rapid temperature change consists of varying the temperature from
-2
0℃
to 6
0℃
, and back again. Power is not applied during the test. After temperature cycling, the
unit is placed in normal room ambient for at least 4 hours before power on.
Note 2
: EN61000-4-2, ESD class B: Certain performance degradation allowed
No data lost
Self-recoverable
No hardware failures.
