LCD Flip
The MultiRAE senses its vertical/horizontal orientation, and can automatically flip the display
180 degrees, making it easy to read if the MultiRAE is upside down. (You can turn this feature
on or off in Programming Mode, under "Monitor/LCD Flip.")
As the MultiRAE is tilted, the gravity sensor detects its orientation and inverts the screen when
it is past its horizontal position.
Key Remapping When LCD Is Flipped
When the instrument is inverted and the LCD flips, the keys are remapped to the functions
shown on the screen.
