4. Remove the oxygen sensor, FIG 4:
(a) Lift up the rear of the sensor where
the connector wires are attached.
(b) Pull the front end of the sensor out
of the retaining collar, arrow right,
molded into the gasket that seals the
two sections of the enclosure.
5. Install the new oxygen sensor:
(a) Align the rear of the sensor as shown
in FIG 5, but do not install.
(b) Insert the sensor into the molded collar, arrow
FIG 6, and align the outer shoulder with the front edge of the collar.
(c) Locate the registration peg indicated by the arrow circled in FIG 5.
(d) Gently press the hole where the wires exit the sensor onto the
registration peg, FIG 5.
6. Connect the sensor, reverse section step 3.
7. Reassemble the device as shown in section 6.4.
8. Calibrate, see section 4.4, the device after replacing
the sensor.
6.4 Reassembly
To ensure proper operation after replacing the sensor or
batteries check the following points:
1. The batteries are secured in the terminal clip.
2. The sealing gasket is registered onto the 4 pegs molded into
the bottom section of the enclosure.
3. The sensor is registered as shown in FIG 5 and FIG 7 and the connecting
wires are not bent or bound when closing up the enclosure and tightening
the Phillips screws, FIG 6.

6.5 Oxygen Sensor Replacement - Optional Remote Sensor
The design of the electronics is intended for only the Analytical Industries Inc.
AII-11-75-PO2 or AII-11-75-PO2R Oxygen Sensors. Use of a different oxygen
sensor may result in an erroneous oxygen reading.
NEVER - Open the oxygen sensor or probe the
sensing surface, refer to Section 10 in the
event the sensor should leak and someone
comes in contact with the electrolyte from inside the
sensor.
With this configuration the integral oxygen sensor is
replaced by a connector module (P/N A-3654). The
external oxygen sensor (P/N AII-11-75-PO2R) is con-
nected to the module by a cable (P/N CABL-1009) with
phone plug and locking nut attached at both ends. The
cable is coiled and extends to 6 ft.
Procedure - Optional Remote Sensor
1. Unscrew the locking nut from the connector located
at the rear of the oxygen sensor.
2. Remove the new replacement sensor from its shipping
packaging.
3. Insert the phone plug into the connector at the rear
of the oxygen sensor and finger tighten the locking nut.
4. Allow the new replacement oxygen sensor to stabilize
for approximately 30 minutes in its new environment.
5. Calibrate, see section 4.4, after replacing the remote
oxygen sensor.
