Key Guide

Mode Button

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.

The default setting for the backlight is off.

Mode Button

Push this button once to switch from one unit of measure to another. This controls which unit of measure your digital level will measure in. Your level has the capability to measure in degrees, percentage of slope and inches/feet in fractions. A symbol on the top of the LCD will show which unit of measure you are currently in.

Push and hold this button in for 3 seconds and then release to enter the automatic shut off mode (5 minutes or 2 hours). When the button is held in for 3 seconds and released the LCD will show a “5” blinking 3 times and then return to the regular display, the automatic shut off is now set to 5 minutes. When the button is held in for another 3 seconds and released the LCD will show a “2H” blinking 3 times and then return to the regular display, the battery icon will be displayed as a reminder that the digital level is now set for 2 hours. The default setting is for automatic shut off in 5 minutes. NOTE: When the battery is low (less than 5%) the digital level will default to 5 minute automatic shut off, the battery icon will begin to flash and there will be no response to pushing this button in for 3 seconds.
