Weighing errors
With four guide elements, there is a risk of the guide elements mutually tensioning, which in
turn induces weighing errors. If you nevertheless want to use four guide elements, the
guide elements must be installed with a sufficient amount of play.
Ensure that the guide elements to be used comply with the principles applicable to weighing
technology.
