ical Position knobs. Use the vertical Position knobs to move the channel
waveformsupordownonthescreen.
Vertical Scale knobs. Use the vertical Scale knobs to control how the oscilloscope
amplifies or attenuates the source signal of channel waveforms. When you turn a
vertical Scale knob, the oscilloscope increases or decreases the vertical size of
th
e waveform on the screen.
Vertical Measurement Overrange (Clipping). Waveforms that extend beyond the
screen (overr ange) and display a ? in the measurement readout indicates an
invalid value. Adjust the vertical scaling to ensure the readout is valid.
Key Po ints
Ground Coupling. Use Ground coupling to display a zero-volt waveform.
Internally, the channel input is connected to a zero-volt reference level.
Fine Resolution. The vertical scale readout displays the actual volts/division
setting while in the fine resolution setting. Changing the setting to coarse does not
change the vertical scale until the Scale control is adjusted.
