Standard Delta F
Oxygen Cells
Figure 1-18 below shows the standard oxygen cell and identifies the
sensing and secondary electrodes. Make oxygen cell connections
from the electrodes on the oxygen cell to the OXYGEN terminal
block on the back of the electronics unit. Use Table 1-6 below to
make oxygen cell connections.
IMPORTANT: To maintain good contact at each terminal block and
to avoid damaging the pins on the connector, pull the
connector straight off (not at an angle), make cable
connections while the connector is away from the
unit, and push the connector straight on (not at an
angle) when the wiring is complete.
