6.4.1 Function
Fig. 6-9 Deflection – Level 1 / Level 2
Use a pulse memory if the pulse is < 50 ms. (See Chapter 6.4.7)
If the pulse is > 50 ms, the stylus magnet (5) deflects the additional stylus (2)
via the stylus lever (4).
With level 1 the stop (3) limits the bar length.
With level 2 current is supplied to the stop magnet (7) too. As a result, the stop's
(3) supporting point is modified.
