Horizontal
Installation
Remove the battery cover of the Main unit. Replace with the battery cover that comes with the Ruler attachment. It
is held by a magnet to the ruler. Store the old battery cover. The Ruler attachment is snapped onto the Main unit in
the Horizontal position. It is held by the magnet, and positioned by plastic index pins which fit snuggly into the
lower 2 screw holes on the back of the case and on both sides of the case, just above the feet. (See picture) Be
certain the latch on the battery cover is snapped securely in place. Be certain that the Main unit is flat against the
ruler.
Hint:
It may be easier to insert the index pins into the lower screw holes first, and then let the magnet swing the
ruler snug with the lower index pins against the top to the Main unit feet.
Vertical Ruler Orientation
The measurement axis may be rotated 90°,
electronically, to read angles with respect
to the vertical axis.
Vertical
The measurement axis may be rotated 90°, to read vertical as zero degrees by holding the Ruler close to vertical and
pressing
ZERO
for about 5 seconds until the readout switches to the vertical angle, for example,
-70° goes to 20
°.
Note: the Main unit remains mounted horizontal to the Ruler, the measurement axis is shifted electronically. In
order to switch back to horizontal as gravity reference, press
START
twice to turn the unit off and back on.
