Trace Oxygen Analyzer Model 316RA/RB/RAD/RBD
NOTE: It is important to minimize the amount of time that the new cell is
exposed to air in order to reduce the time required for the reading
of the newly installed cell to drop to zero.
3. Remove the new cell from its package, remove the shorting
clip, and position it on the cell block plug (contact plate surface
up). Take care that the cell does not come off the plug flange
and that the flange does not scrape across the sensing
membrane, which will render the cell unusable.
4. Insert the cell into the cell block and tighten the cell block plug
to seat the o-ring seal.
5. Immediately start sample flow, and set at 2 SCFH.
6. Allow the reading to drop to a stable low value and immediately
proceed to the Calibration section.
Spare Cells
If you wish to prevent the possibility of not having a replacement cell
available when needed, order a spare cell shortly after placing the Series
316 in service, and after each time the cell is replaced.
NOTE: Do not stockpile spare cells. Only one cell per instrument should be
in reserve.
The spare cell should be stored in an area free from large variations in
ambient temperature (75°F nominal), or any possibility of damage. Do not
open the cell package until the cell is to be used. If the cell package is
punctured and air permitted to enter, the cell will immediately start to react
to the presence of oxygen, shortening cell life.
Warranty Conditions
The Class B-2 cell used in the Series 316 is warranted for six (6)
months of service beginning from date of shipment. The B-2 cell should
not be used in applications where CO
2
is a major component in the sample.
Concentrations of 1,000 ppm or less will not affect cell performance.
Optional cells are available for either intermittent or continuous CO
2
exposure.
Customers having warranty claims must return the cell in question to
the factory for evaluation. If it is determined that failure is due to faulty
workmanship or material, the cell will be replaced free of charge.
NOTE: Evidence of tampering or mishandling will render the cell warranty
null and void.
If a cell was working satisfactorily, but fails short of its warranty
period, the customer will receive credit, on a pro-rated basis, toward the
purchase of a new cell.
