    Activate a sine wave signal (better identical frequency) on both channels of the generator. By regulators Amplitude and Balance of the small window establish visually by the scope the maximal identical amplitude of signals on channels without distortions of the form (flat tops).
    Thus the mutual vertical displacement of traces can take place. To remove it, switch off the generator completely, then by the regulators of the constant component of small window separately displace the traces to a zero horizontal. To make the trace of the 1-st channel visible, the deenergizing of the scope synchronization can be necessary.
