instrument, or calibration cannot be achieved within the range of the
buttons, the cell may need replacing. Read the section Cell Warranty
Conditions, below, before replacing the cell.
In addition, if the front panel Percent Oxygen Meter displays
"0.00" when the unit is plugged in, and the power switch is in the ON
position, the sensor needs to be replaced.
IMPORTANT: After replacing the oxygen sensor, the analyzer
must be recalibrated. See Calibration in Chapter 4.
5.2.2 Ordering and Handling of Spare Sensors
To have a replacement cell available when it is needed, TAI
recommends that one spare cell be purchased shortly after the instrument
is placed in service, and each time the cell is replaced.
Note: Do not stockpile cells. The warranty period starts on the
day of shipment. For best results, order a new spare cell
when the current spare is installed.
The spare cell should be carefully stored in an area that is not
subject to large variations in ambient temperature (75° F, 23.9°C
nominal), and in such a way as to eliminate the possibility of incurring
damage.
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, CELL-LIFE WILL BE
COMPROMISED.
CAUTION:
THE SENSOR USED IN THE MODEL 3290 USES
ELECTROLYTES WHICH CONTAIN SUBSTANCES
THAT ARE EXTREMELY HARMFUL IF TOUCHED,
SWALLOWED, 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 OR ADDENDUM,
MATERIAL SAFETY DATA SHEET—MSDS).
