Teledyne 3110 – Portable Trace/Percent Oxygen Analyzer, FM-approved configuration - Manual (Page 12)

Introduction Model 3110
Teledyne Analytical Instruments 4
1.4 Micro-Fuel Cell
The micro-fuel cell (U.S. Pat. Nos. 3,767,552 and 3,668,101) is a
sealed electrochemical transducer with no electrolyte to change or
electrodes to clean. When the cell reaches the end of its useful life, it is
thrown away and replaced. The life of the cell is warranted by TAI (see
below).
The cell is specific for oxygen and is not sensitive to flowrate or
reducing agents such as hydrocarbons, carbon monoxide, sulfur dioxide,
etc. In the absence of oxygen, no current is produced; thus, no zeroing is
required.
1.4.1 Cell Warranty
The Class B1, B2-C, A2C, B2C-XL, Insta-trace and NG series
micro-fuel cells used in the Model 3110 carry a six (6) month warranty.
With regard to spare cells, service time starts when the cell is
removed from its shipping package. You should stock only one spare
cell per instrument at a time.
If a cell was working satisfactorily but ceases to function before the
warranty period expires, you will receive credit on a pro-rated basis
toward the purchase of a new cell.
If you have a warranty claim, 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 at no cost to you.
WARNING: EVIDENCE OF DAMAGE DUE TO TAMPERING OR
MISHANDLING WILL RENDER THE CELL
WARRANTY NULL AND VOID.
The Model 3110 is rated as intrinsically safe and may be used in a
Class I, Div 1, Group A-D hazardous environments.
This safety feature does not apply when the instrument is being
charged with the 100- 240 VAC external charge adapter. The instrument
should be removed from hazardous areas when the batteries are being
charged.
Note: Do not use the analyzer when the battery level is low.
