9. Compare the four lines by drawing a straight line along
the lowest and highest reference lines. If the distance
between these two lines is less than the Total allowable
deviation of 9mm at 15m or 18mm at 30m, the instrument
is properly calibrated.
However, if the measured deviation is more than the stated
tolerances, repeat the accuracy check procedure. Should the
readings persist over the allowable deviation, the instrument
is OFF calibration.
