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