•As crimp terminals A, B, SA, SB and C have their own electrical potentials, securely insulate them so as not to come in contact with one another.
•To prevent a shield from coming in contact with another shield or the case, cover each shield with a vinyl tube or wrap it in vinyl tape.
NOTE
Conductors A and B carry the signal from the electrodes, and C is at the potential of the liquid (signal common). Shields SA and SB are kept at the same potentials as the individual elec- trodes (these are actively driven shields.) This is done to reduce the effect of the distributed capacitance of the cable at long cable length. Note that, since the signals from the individual electrodes are impedance converted inside the converter, errors will result if they come in contact with any other component. Great care must be taken in the cable end treatment.
(2)Excitation Cable/Power Cable/Output Cable
Use polyvinyl chloride insulated and sheathed control cables (JIS C 3401) or polyvinyl chloride insulated and sheathed portable power cables (JIS C 3312) or the equivalent.

NOTE
•For excitation and power cables, always use a crimp terminal with an insulation cover.
•Use crimp tools from the manufacturer of the crimp terminal you want to use to connect the crimp terminal and cable.
•Use crimp tools that are appropriate for the diameter of the cable to be connected.
