3 General Care & Safety 4 Specifications This means CAUTION. Users must familiarize themselves with the instructions that accompany the use of this symbol. Users must read and understand this manual before using the AII-4001 Helium Oxygen Analyzer. The AII-4001 displays the MOD or maximum operating depth @ 1.4 ATA of the mix under analysis.

Operation 5.1 Controls The AII-4001 is equipped with a waterproof membrane type panel that contains three color coded push button keys for operating the analyzer. POWER - press and release the RED key to turn the unit ON or OFF BACK LIGHT - the YELLOW key has two functions: 1) press and release it to turn the backlight ON or OFF 2) press and hold the YELLOW key for 3 seconds to switch the LCD display between Imperial and Metric units 5.

5.3 O2 Calibration and He Zero The AII-4001 employs proprietary maintenance free long life Helium and Oxygen sensors that measure in the 0-100% range. The Oxygen sensor is automatically compensated during calibration for temperature, relative humidity and pressure, thereby eliminating the need for conversion charts. The Helium sensor is characterized using a six point linearization curve. Further, the Helium output is compensated for differences in thermal conductivity of Oxygen and Nitrogen.

6 Maintenance The AII-4001 contains no moving parts and other than a periodic wipe down requires no routine maintenance. The expected life of the Helium sensor is 10 years and along with the environmental sensor module should last for the life of the analyzer, unless subjected to contact with liquids or excessive shock from the analyzer being dropped. The expected life of the Oxygen sensor is 5 years in air (20.9%) at 25⁰C (77⁰F) and 1 atm.
