description of each LCD screen control button used
in this procedure.
Plus Minus
Digital levels with alternate zero function:
Note: Prepare the digital level by placing it vertically
on a known surface that is perpendicular to gravity.
Zero out the level with the alternate zero function.
Note: When the level is calibrated correctly, it
should read 0° on a vertical surface.
Digital levels without alternate zero function:
Note: If your digital level does not have an alternate
zero function, it will read 90° on a vertical surface.
During calibration, the measured value will need to
be subtracted from 90 degrees to get the correct
number to enter into the system.
