•U : B+ Line.
•V : B– Line.
•Voltages and waveforms are dc with respect to ground under
•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances.
•Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc- tion tolerances.
•Circled numbers refer to waveforms.
•Signal path.
