1.9.4.1 Standard Delta F Oxygen Cells
Figure 20 below shows a standard Delta F 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 moisture.IQ. Refer to Figure 18 on page 22 and Table 2 below for the required 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.
Note: The temperature reading of the sensor is used for internal temperature compensation and does not
require any user setup.
