ABSTRACT:
The invention relates to a method for positioning a pen in a recording device for recording the time profile of a measurement signal which can be connected. In order to implement the highest possible mapping accuracy of the measurement signal onto the recording signal at a low cost and with DC isolation between the measurement signal and drive means of the pen, it is proposed that the positioning error (300) be phase-width modulated, the pulse-width-modulated positioning error (400) be transmitted in a floating manner to a signal converter (70), and a control voltage for the electric motor (90) be determined using the signal converter (70) from the pulse-width-modulated positioning error (400) by normalizing the difference between the pulse duration and the pulse-pause duration, via the sum of the pulse duration and the pulse-pause duration.
