Instructions

Digital Storage Oscilloscope 55
Auto Scale: Automatically set the oscilloscope controls to generate a usable display of
the input signals. Refer to the following table for relative content.
Single: Acquire a single waveform and then stop the acquisition.
Run/Stop: Continuously acquire waveforms or stop the acquisition.
Help: Display the Help menu.
Default: Recall the factory setup. Refer to the following table for relative content.
2.13.1 AUTO SCALE
Auto Scale is one of the advantages digital oscilloscopes have. When you push the
Auto Scale button, the oscilloscope will identify the type of waveform (sine or square
wave) and adjust controls according to input signals so that it can accurately display
the waveform of the input signal.
