Important safety notice:
Components
identified
by
mark
have
special
characteristics important for safety.
Furthermore, special parts which have purposes of fire-
retardant (resistors), high-quality sound (capacitors), low-
noise (resistors), etc. are used.

The voltage values and waveforms are the reference
voltage of this measured by the DC electronic voltmeter
(high impedance) and oscilloscope on the basis of GND
terminal (DC IN jack). Accordingly, there may arise some
errors in the voltage values and waveforms depending upon
the internal impedance of the tester or measuring unit.
