Abstract
In order to eliminate internal faults of the instrument, only the relevant service instructions should be consulted. In the case of external interference, however, certain remedies of general validity apply. If several adjacent pulse instruments with not exactly identical repetition frequencies are used, the pulses are transmitted from one instrument to the other electrically and they travel over the image. This requires synchronisation of the repetition frequencies of the instruments concerned. Instruments designed for use in testing installations usually are equipped with this synchronisation facility. If not installed, synchronisation usually is possible by slightly changing the wiring. For this purpose it is recommended to consult the manufacturer.
