-The voltage value and waveiorms 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.
