Check the Vertical Readout at the bottom-left part of the display to read the
volts/division setting for each displayed channel (the selected channel is in
inverse video). (See Figure 3–6.)
The TDS Oscilloscope permits you to change vertical scale and position quickly
from the front panel using dedicated control knobs. To change the vertical scale
and position:
1. Turn the vertical SCALE knob. Note only the scale of the selected wave-
form changes.
As you turn the vertical SCALE knob clockwise, the value decreases
resulting in higher resolution because you see a smaller part of the wave-
form. As you turn it counterclockwise, the scale increases allowing you to
see more of the waveform but with lower resolution.
