WARNING: THE SENSOR USED IN THE MODEL 3000TA-XL TRACE OXYGEN ANALYZER USES ELECTRO- LYTES WHICH CONTAIN TOXIC SUBSTANCES, MAINLY LEAD AND POTASSIUM HYDROXIDE, THAT CAN BE HARMFUL IF TOUCHED, SWAL- LOWED, OR INHALED. AVOID CONTACT WITH ANY FLUID OR POWDER IN OR AROUND THE UNIT. WHAT MAY APPEAR TO BE PLAIN WATER COULD CONTAIN ONE OF THESE TOXIC SUBSTANCES. IN CASE OF EYE CONTACT, IMMEDIATELY FLUSH EYES WITH WATER FOR AT LEAST 15 MINUTES. CALL PHYSICIAN. (SEE APPENDIX, MATERIAL SAFETY DATA SHEET.)
CAUTION: Do not disturb the integrity of the cell package until the cell is to actually be used. If the cell package is punctured and air is permitted to enter, the cell will require an excessively long time to reach zero after installation (1-2 weeks!).
5.2.2 When to Replace a Cell
Cell failure in the 3000TA-XL is usually characterized by a significant increase in the zero offset of more than 1.0 ppm oxygen or the inability to calibrate the sensor. When this occurs, the 3000TA-XL will still Zero but the system alarm trips, and the LCD displays a failure message.

Before replacing the cell:
a.Check your span gas to make sure it is within specifications.
b.Check for leaks up-stream from the cell, where oxygen may be leaking into the system.
If there are no leaks and the span gas is within specification, replace the
cell.
