Why does ElmaTear2 detect the wrong pendulum during calibration?

The ElmaTear2 detects which pendulum is fitted by measuring the time taken for the pendulum to drop after it is released. If there is any friction or delay in the release of the pendulum this will lead to the wrong pendulum being detected.

Full instructions to solve this, including diagrams and images, can be found in the PDF document.
