Refer to Figure 2-5 and connect the sensor (or intercon-
nect) cable wires to Terminals 4 through 8 on TB3 and
Terminal 1 on TB4, matching colors as indicated.
NOTE:
For best immunity to electromagnetic interference,
always connect the sensor cable’s shield wire to a
terminal on TB2 instead of to Terminal 5 on TB3.

The electrode must be within 100 ft. (30 m) of the analyzer
(985 ft./300 m for electrode with preamp). Refer to Figure
2-6 and directly connect the electrode’s coaxial cable to the
analyzer.
