some error in voltage values and waveforms depending upon the
internal impedance of the tester or the measuring unit.
- Importance safety notice :
Components identified by
important for safety. Furthermore, special parts which have purposes
of fire-retardant (resistors), high-quality sound (capacitors), low-noise
(resistors), etc. are used. When replacing any of components, be sure
to use only manufacturer's specified parts shown in the parts list.
Caution !
