ALT ZERO
(Setting an alternate reference point)
ALT ZERO allows you to set any angle as a 0.0° reference point from which to take
measurements. For example, you may want a surface that is actually 3° off horizontal
displayed as 0° so you can measure all other angles from that benchmark.
To set an alternate reference point, place the Pro 360 on the new surface and wait 5
seconds. Press the ALT ZERO button once. "
Alt "will appear on the display, followed
by "-0-" . The Pro 360 will then display angles using the new reference. A flashing

will appear in the lower right hand corner of the display as long as the Pro 360 is in ALT
ZERO mode.
Press ALT ZERO again to return to standard reference mode. The Pro 360 also returns to
standard reference when it is turned off or shuts off automatically.
NOTE: You cannot activate the ALT ZERO button when the Pro 360 display is in HOLD.
