screen will first briefly display all of the angle-calculation elements and
then display the relative angle between the folding leg and the base leg.
b. When the device is turned on, briefly pressing the button again will flip the
display on the screen.
c. Press the button and hold it for about 3 seconds to turn off the tool.
d. When the Digital Angle Finder is inactive for 5 minutes, it will automatically
turn off to save battery power.
3. TO USE THE DIGITAL ANGLE FINDER BUBBLE VIALS FOR LEVEL AND
PLUMB MEASUREMENTS
NOTE:
Use the highly accurate bubble vials to establish level or plumb surfaces. The LCD
display is for use in making relative-angle measurements only; it is not useful for level
and plumb measurements. The LCD display may be turned off for this function.
Horizontal measurement
Place the Digital Angle Finder on the work surface; the surface will be at true
level when the bubble is positioned exactly between the marks on the vial.
Vertical measurement
Place the Digital Angle Finder against a vertical work surface; the surface will be
at plumb (true vertical) when the bubble is positioned exactly between the marks
on the plumb bubble vial.
