10. Voltage Measurement and Waveform Chart

Note:
- Indicated voltage values are the standard values for the unit
measured by the DC electronic circuit tester (high-impedance)
with the chassis taken as standard.
Therefore, there may exist some errors in the voltage values,
depending on the internal impedance of the DC circuit tester.
- Circuit voltage and waveform described herein shall be regarded
as reference information when probing defect point because it
may differ from actual measuring value due to difference of
Measuring instrument and its measuring condition and product
itself.
