4. Remove the new cell from its package, and carefully remove the
shorting wire. Do not touch the silver/gold colored sensing
surface of the cell as it is covered with a delicate Teflon
membrane that can be ruptured in handling.
5. The cell has three pins that fit into the cap one way only. Slide
the pins into the cell cap.
6. Replace the cell cap and cover.
7. After the cell has been installed, purge the instrument with an
inert gas (or the sample), and then proceed as directed in the
calibration procedure.
Cell Warranty
The Class S-2 cell used in the Model TURBO
2
is warranted for 6
months of service from date of shipment.
The Model TURBO
2
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 effect cell performance.
If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit, on a prorated basis,
toward the purchase of a new cell.
Customer having warranty claims must return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty work-
manship or material, the cell will be replaced at no cost to the customer.
CAUTION: Evidence of damage due to tampering or mishandling will render
the cell warranty null and void.
Transduction and Temperature Compensation
The Micro-fuel Cell used in the TURBO
2
has an inherent positive
temperature coefficient, the effects of which have been minimized through
the implementation of a thermistor compensation circuit.
