Measure the length of the fourth offcut. The accuracy
11.
of this measurement is not critical, so a standard tape
measure or ruler will suffice.
Measure the width of the fourth offcut at both ends (as
12.
labeled "Right" and "Left"). These two measurements
are critical, so use the best method you can.

The equation for calculating the error is shown below,
however, the electronic version of this manual also
contains a built-in calculator. To use the calculator, enter
your measurements (in either mm or inches) in the boxes
and click on the "Calc Error" button. The calculated error
(angle) is displayed to the right of the button.
