Once it has been established that the sensor impedance is normal, the sensor offset may be tested and set. Refer to Section 5.5.10 & 5.5.11. A normal flow of air must be in the gas sample line when testing sensor offset. 3.14 SENSOR CALIBRATION – OXYGEN SENSOR Page 20 Teledyne Analytical Instruments 9070 Oxygen Analyzer... - Page 21 • Don’t connect the test gas directly to the sample pipe of the 9070. Allow the Analyzer to suck the gas in using the internal pump, as it would in normal use. This can be done by piercing a plastic hose on the outlet of the gas bottle with the hypodermic needle.
- Page 22 Insert the sample hypodermic needle into a hose from a gas supply of 100% CO Open the gas supply and let at least 1 litre per minute flow through the hose. (The 9070 will draw less than 0.5 lpm) Leave the 100% gas flowing through the Analyzer for at least 30 seconds.

Occasionally, a sensor can develop offset with a polluted electrode caused by contaminants in the sample gas stream. In this case, the old electrode material must be completely cleaned off before re-applying the fresh electrode material.
