Horizontal Calibration
Put the angle level on a smooth level plane and observe the LCD
display. Note the reading after ten seconds. Then turn the angle
level 180º on the same plane. After another ten seconds note the
second angle reading. Calibration is necessary if the difference
between the two measuring readings is over 0.1º.
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
