Zero Button - Absolute/relative angle conversion button for comparison of twowork surface angles.1. When the level is first turned on, it is in the absolute angle mode anddisplays the angle from true level.2. Take a measurement of the first work surface; the LCD screen indicates theangle between that surface and true level.3. Press the zero button for the relative angle mode, and the level will set thefirst angle to zero.4. Move the digital level to the second work surface, and the LCD screenindicates the relative angle between the first and second surfaces.5. To return to absolute angle again, turn the power button off and back on.Convert Button – Converts the angle display on the LCD screen among 3different units.• Press the button to proceed through the display units: Degrees (º), Slope (%),and Pitch (in/ft).• Pitch readings are in increments of 1/8-in. per ft. Plus and minus signsindicate whether the pitch is slightly more (+) or slightly less (-) than the pitchthat is shown on the display.Hold ButtonTo hold the information of the current reading, press the Hold button to freezethe displayed reading; press it again to return to measuring mode.TO USE THE LEVEL FOR HORIZONTAL AND PLUMB MEASUREMENTSHorizontal and Plumb measurements can be made with both the bubble vial andthe LCD display featuresHorizontal• Use the level on horizontal surfaces to determine when they are level. Placethe level against the horizontal surface. The surface will be at true level whenthe bubble is positioned exactly between the marks on the level vial.• The LCD display represents the surface you are measuring as a line, eitherabove or below the 0, or “true level,” line, with an arrow showing whether thesurface should be raised or lowered in order to be level. The digital displayshows the degree to which the surface is “out of level.” If the sound is turnedis on, the level will beep when true level, or 0°, is reached.48295 Manual_Revised_07-0620 Page 7
