• The voltage value and waveforms are the reference voltage of this measured by DC electronic voltmeter (high impedance) and oscilloscope on the basis of chassis.
  Accordingly, there may arise some errors in the voltage values and waveformsdependingupon the internal impedance of the tester or the measuring unit.

• Important safety notice:
  Components identified by mark have special characteristics important for safety. When replacing any of these components, use only manufacture’s specified parts.

• This schematic diagram may be modified at any time with the development of new technology.
