3.3.4 Remote Probe Connection
The Models 3010TAC are split architecture (dual-chassis) instru-
ments, which have a Remote Probe, or Analysis Unit. The remote probe is
for receiving the oxygen sensor and thermistor signals. See Figure 3-7 for
remote probe connection. The connections of the Analysis Unit are covered
in detail in Part II, section 3.4, of this manual.
