14.
Use
to slow the time base to 500 ms/DIV.
15.
Use
to set the range to 2 V/DIV.
Figure 8-12 Trigger on AC Coupling
The slope of the waveform between the switching edges
indicates that it was set for AC coupling. But accurate low
frequency measurements require DC coupling. To choose
DC coupling again, do the following:
16.
Press .
17.
Use
to select DC coupling (indicated on the top
left of the display).
There should be two correctly formed pulses on the display.
Reduce the time base further to see the complete
waveform.
18.
Use
to slow the time base to 1sec/DIV.
The waveform is a 0.5s pulse that occurs every 4 seconds.
(See Figure 8-13.)
