Knobs
Vertical Position Knobs. Use the Vertical Position knobs to move the channel
wavefo
rmsupordownonthescreen.
Vertical Scale (volts/division) Knobs. Use the Vertical Scale knobs to control h ow
the oscilloscope amplifies or attenuates the source signal of channel waveforms.
WhenyouturnaVertical Scale knob, the oscilloscope increases or decreases the
vertical size of the waveform o n the screen.
Vertical Measurement Overrange (Clipping). Adisplayof? in the measurement
readout indicates an invalid value. This may be due to waveforms that extend
beyond the screen (overrange). Adjust the vertical scaling to ensure the readout
is valid.
Key Points
Gr
ound 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 Vertical Scale control is adju sted.
