7. The voltage value. and waveforms are the reference voltage values of this unit
measured by DC electronic voltmeter (hlgh-impedance) and oscilloscope on
the basis of chassis. Theretore, the voltage value and INBveform may include
some error due to the interr"lal impedance of the tester or the measuring
set .
