SENSOR REPLACEMENT
When the sensor’s (CO, Comb., and O
2
) near the end their useful life, sensitivity will decline
rapidly and the readings will be very unstable. Refer to “Operator’s Checks & Adjustment” -
Messages and Failure Warning Signs for further details. For sensor replacement, refer to
“Installation Procedures.”
AFTER REPLACING ANY SENSOR, PROCEED TO THE “INSTRUMENT OPERATING
PROCEDURE” SECTION FOR CALIBRATION.
Important: To avoid the possibility of not having a replacement cell available when it is
needed, Teledyne recommends that a spare cell be ordered shortly after the instrument is placed
in service, and each time the cell is replaced thereafter.
Caution: DO NOT OVER ORDER (OR STOCKPILE) SPARE CELLS. Only one cell per
instrument should be in reserve.
