H
Push the front-panel AUTOSET button. This sets the horizontal and
vertical scale and vertical offset for a usable display and sets the trigger
source to the channel that you are testing.
H
Touch the Vert button and then touch Offset . Confirm that the Ch1
Offset is about
--0.18 to --0.54 V
(0.0 V if not using a probe).
6. Verify that the channel is operational: Confirm that the following statements
are true.
H
Verify that the vertical scale readout and the waveform amplitude for the
channel under test are as shown in Table 1--3.

H
The front-panel vertical POSITION knob (for the channel you are
testing) moves the signal up and down the screen when rotated.
H
Turning the vertical
SCALE
knob counterclockwise (for the channel you
are testing) decreases the amplitude of the waveform on-screen, turning
the knob clockwise increases the amplitude, and returning the knob to
the original scale setting returns the amplitude to that shown in
Table 1--3 for that scale setting.
