15 Appendix Information of Schematic Diagram
15.1. Voltage & Waveform Chart
Note:
• Indication Voltage Values are in 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 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.
