Advanced Instruments Inc.
3 Safety
Serviceability: Except for replacing the oxygen sensor, there are no parts inside the analyzer for the
operator to service.
Only trained personnel with the authorization of their supervisor should conduct maintenance.
Oxygen Sensor: DO NOT open the sensor. The sensor contains a corrosive liquid electrolyte that could
be harmful if touched or ingested, refer to the Material Safety Data Sheet contained in the Owner’s
Manual appendix. Avoid contact with any liquid or crystal type powder in or around the sensor or sensor
housing, as either could be a form of electrolyte. Leaking sensors should be disposed of in accordance
with local regulations.
Troubleshooting: Consult the guidelines in Section 8 for advice on the common operating errors before
concluding that your analyzer is faulty.
Do not attempt to service the analyzer beyond those means described in this Owner’s Manual. Do not
attempt to make repairs by yourself as this will void the warranty as per Section 9 and may result in
electrical shock, injury or damage. All other servicing should be referred to qualified service personnel.
Cleaning: The analyzer should be cleaned only as recommended by the manufacturer. Wipe off dust
and dirt from the outside of the unit with a soft damp cloth then dry immediately. Do not use solvents or
chemicals.
Nonuse Periods: Isolate ppb and ppm oxygen sensors as described in this manual and disconnect the
power when the analyzer is left unused for a long period of time.
