Abstract: A multi-channel printer with a time profile recorder for recording time profiles of measured values and electrical connectors for detachable connection of signal connecting leads for measured value sources which is installed in grid-based switch panels or control panels. In further developing of such a flush-mounted printer in such a manner that the number of connecting elements available for signals supplied on separate leads is as high as possible despite the limited rear area will be proposed in the invention, that the time profile recorder (11) for recording time profiles of measured values and the electrical connector (12) for the detachable connection of signal connecting leads (3) for measured value sources are physically separated and are electrically connected to one another via connecting leads (13).

Abstract: The present invention is embodied as an arrangement for positioning a pen in a device that records the time profile of a measurement signal which can be connected to the device. The arrangement provides high 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. The arrangement uses a control loop that has a pulse width modulator whose output is DC-decoupled to a signal converter that provides the drive signal for the motor that moves the pen.

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.

Abstract: A multi-channel recording device for recording the time profiles of a plurality of measurement signals which can be connected to the device. The device has first and second groups of optical indicators on the front of the device and scale strips corresponding to the physical variables to be measured. There are n indicators in the first group, m indicators in the second group and scale strips where n is greater than m. The device assigns one and only one of the m indicators to each of the n indicators.
