Signal line

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.

No mark :

Importance 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. When replacing any of components, be sure to use only manufacturer’s specified parts shown in the parts list.

Caution!

IC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair.

Cover the parts boxes made of plastics with aluminium foil. Ground the soldering iron.

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.

No mark :

Importance 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. When replacing any of components, be sure to use only manufacturer’s specified parts shown in the parts list.

Caution!

IC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair.

Cover the parts boxes made of plastics with aluminium foil. Ground the soldering iron. Put a conductive mat on the work table. Do not touch the pins of IC, LSI or VLSI with fingers directly.
