Gravity means a vector pointing from the device toward the center of the earth.

X means a vector parallel to the white silkscreen arrow “X” printed on the main circuit board.

Y means a vector parallel to the white silkscreen arrow “Y” printed on the main circuit board.

Z means a vector passing through the white silkscreen dot “Z” printed on the main circuit board, at 90º to the board.

Horizontal means the silkscreen arrow is pointing at a right angle to Gravity.

Straight Down means the silkscreen arrow is parallel to Gravity.

Straight Up means that the silkscreen arrow is anti-parallel to Gravity (i.e. pointing toward the sky).

Plumb Line is a line with a weight on the end hanging straight down.

In Dual Axis Tilt Mode the X Tilt and Y Tilt angles are measured between Gravity and the white silkscreen arrows printed on

the main circuit board. If you passed a Plumb Line through the inclinometer’s X, Y, Z origin, the X and Y Tilt angles could

be measure by placing a protractor’s straight edge on the plum line and then reading the angles made with each arrow.

Y Tilt = Pitch (first angle)

X Tilt = Roll (second angle)

Holding Y Horizontal

When X is Horizontal, X Tilt = 90 º.

When X is Straight Up, X Tilt = ~180 º.

When X is Straight Down, X Tilt = ~0 º.

Holding X Horizontal

When Y is Horizontal, Y Tilt = 90 º.

When Y is Straight Up, Y Tilt = ~180 º.

When Y is Straight Down, Y Tilt = ~0 º.
