Vertical position is set to 0 divisions and vertical
offset to
0 V when the 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 1–4.
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 1–4.
f. Check against limits: Do the following subparts in the order listed.
CHECK that the measurement results are within the limits listed for
the current vertical scale setting.
Enter voltage on test record.
Repeat substeps b through f until all vertical scale settings listed in
Table 1–2, are checked for the channel under test.
