Understanding the reference angle

iLevel can easily be used to measure differences between angles on surfaces. The difference is measured between the current (continuously measured) angle and a stored angle. With no stored angle selected, differences are measured against 0° | 0°.

Measuring differences

The picture below shows how to measure the difference to a stored angle.

  • Marker 1 highlights the selected stored angle.
  • Marker 2 highlights the angular differences.
