Oscilloscope Patterns and Waveforms

Wave Pattern Check Using an Analyzer




MEASUREMENT METHOD
Connect the analyzer special patterns pick-up to the generator "B" terminal.

Observation Conditions:

STANDARD WAVEFORM






NOTE: The voltage waveform of the generator "B" terminal can undulate as shown at left. This waveform is produced when the regulator operates according to fluctuations in the generator load (current), and is normal for the generator. If the ripple height is abnormally high (approximately 2 V or more during idling), the wires between the generator B terminal and the battery have broken due to fuse blowing, etc. The generator is usually operating properly.
