oscilloscope is initialized in step 1.
c. Display the test signal: The waveform position and offset were
initialized for all channels in step 1 and are displayed as you select each
channel and its vertical scale.
d. Measure the test signal: Align the active cursor over the waveform by
rotating the general purpose knob. Ignore the other cursor. See
Figure 4–4.
e. Read the measurement results at the absolute (@:) cursor readout, not
the delta (D:) readout on screen. That is, read the offset relative to the
ground reference. See Figure 4–4.
f. Check against limits: Do the following subparts in the order listed.
H CHECK that the measurement results are within the limits listed for
the current vertical scale setting.
H Enter voltage on test record.
