Operating Instructions
- Switch the OX™-100 to the CAL position.
- With the sample probe in ambient air, calibrate the oxygen reading to 20.9% by adjusting the calibration knob.
- Switch the OX™-100 to the ON position. Insert the probe into the pipe and depress the sample button once to take a reading.
Maintenance
IMPORTANT: To prolong the life of the oxygen sensor, the sponge filter should have the moisture squeezed out of it whenever it is saturated. This will vary with the moisture content of the sample and initially should be checked after every 20 samples. The sponge filter may be washed in ordinary soap and water. Be sure to thoroughly rinse and dry the filter before reinstalling it. After extended use, the lead pellets may corrode and deteriorate. When this occurs, return the analyzer to the Aquasol Corporation for service.
The Oxygen Sensor
The OX™-100 Oxygen Sensor is a small, fuel cell that measures oxygen volume directly. The size of a “C” cell flashlight battery, the OX™-100 oxygen sensor is disposable.
Oxygen Sensor Replacement
If sensor will no longer calibrate it should be replaced.
- Unscrew sensor cover retaining screw.
- Loosen black and red sensor lead screws.
- Remove oxygen sensor and clean out housing.
- Before replacing sensor, insert new sensor leads under black and red sensor lead screws.
- Place sensor in housing with plain end up and sensing end (with hole) down.
- Tighten black and red sensor lead screws.
- Replace sensor housing cover and tighten retaining screw.
- Recalibrate the OX™-100.
OX™-100 Storage
The OX™-100 should be stored in a location where it will not be subjected to temperature extremes. It should never be stored in temperatures below 32°F (0°C) for extended periods of time.
Short Term Storage
To extend the life of the sensor and batteries, remove after use. However, if impractical, do not store the oxygen sensor and batteries for more than one month in the unit. To further prolong battery life the OX™-100 should be switched to the OFF position when not in use.
Long Term Storage
The batteries and oxygen sensor should be removed when the OX™-100 is to be stored for more than a month. The oxygen sensor should be stored in its vial. Additional sensor life can be obtained by refrigerating the sensor in its vial at recommended temperature range of 40°- 45°F (4°- 7°C). Care should be taken NOT to FREEZE the unit.
OX™-100 Troubleshooting
- Check particulate filter or lead condensing balls for clogs.
- Clean and dry sensor and housing.
- Check sensor lead connections for tightness or corrosion.
- Recalibrate the OX™-100.
