On/Off: Holding this button down for several seconds turns the LCD display on or off. The

Everything on the display will flash except the number while the reading is being held. Press
the button again to stop holding the reading.
3. 0% (percent): This button switches the LCD display between displaying the angle in degrees
and displaying the angle as a percent difference from 0° or 90°.
4. Calibrate (Zero Setting): This button toggles between reading 0 at the current angle and
reading the actual angle. Press the “Calibrate” button once to change the current reading
to 0° or 0%. Press the “Calibrate” button again and hold it to restore the level to reading the
actual angle. The level will reset to reading the actual angle if it is switched off. Note:
