C: USING AN OSCILLOSCOPE
A malfunction can be determined by displaying the waveforms
of input/output signals on the oscilloscope.
1. DIAGNOSIS
A simple comparison of the waveforms may lead to an incor-
rect diagnosis. To exactly determine the sources of the mal-
function it will be necessary to determine them under consid-
eration about information other than waveforms.
2. APPLYING INPUT/OUTPUT SIGNALS
Connect the probe directly with the terminal of the signal.
