The top of the adapter has 10 pins - four pins for the coils, four pins for the electrodes, and
two pins for the process reference. Each connection point has two pins associated for
redundant continuity. See Figure 12-2.
The best location for testing the sensor components is taking measurements directly on
the feed-through pins. Direct measurement on the pins eliminates the possibility of an
erroneous measurement caused by a bad socket module or remote wiring. The figure
below shows the feed-through pin connections as they relate to the terminal connections
described in the tests.

Sensor adapter direct lead pins
The sensor adapter direct leads are the part of the sensor that provides the direct
connection from the internal sensor components to the terminal block connections. The
top of the adapter has 6 pins - three pins for the coils, and three pins for the electrodes.
See Figure 12-3. The best location for testing the sensor components is taking
measurements directly on the slot pins. Direct measurement on the pins eliminates the
possibility of an erroneous measurement caused by a bad terminal block or remote wiring.
Figure 12-3 shows the slot pin connections as they relate to the terminal connections
described in the tests.
