Key Guide

ON/OFF Button
Push this button once to turn on the digital level. Push and hold this
button in for 3 seconds to turn the digital level off. When in REF
Mode, push the on/off button once to exit REF Mode.

Reference/Backlight Button
Push this button once to enter Reference Mode. The reference
function allows for setting any angle or slope to “0.0”. This is very
useful for measuring the same slope continuously during a project or
finding the difference between two slopes. To set the reference
function, position the level at the desired angle you wish to measure.
Press and release the reference button. REF will appear on the
screen while in the reference mode and the numbers will go to 0.0.
Set the level on the second surface to measure the difference
between the first and second surface. Each time the REF button is
pushed one time, the LCD will be set to 0.0. To exit this reference
mode, press the on/off button one time.
