Carefully position a 2% inch long piece of shrink tubing or tape on the bare sensor shield wire %-inch from the end as shown in Figure 2-6 to insulate and distinguish it from the inner shield wire. Doing this exposes X-inch of bare shield wire beyond the tubing or tape for connection purposes. 6. Carefully position a l-inch long piece of shrink tubing or tape on the cable as shown in Figure 2-6 to secure all wires.
