1 Introduction

Congratulations you have purchased the most advanced portable gas analyzer
available. The AII-4001 provides unmatched sophisticated performance in a
simple to use package, and, provides users with significant advantages:

Precisely analyze dive gas mixes in any environme nt withou t charts. Propri etary
algorithms* and sensors provide extremely accurate one touch calibration.
Note: Failure to account for environmental factors can produce up to 6.7%
error.

 Oxygen is compensated for temperature, barometric pressure and RH.
 Helium is zeroed when the oxygen is calibrated with air or 100% oxygen.

Algorithms* compensate the Helium value for differences in the thermal con­ductivity of Oxygen and Nitrogen enabling the AII-4001 to precisely measure
any combination of Helium, Oxygen and Nitrogen.

The large backlit LCD is easily read even in low light condition and provides
additional information to the user:
 Temperature, barometric pressure and RH values of the sample gas.
 For added safety, the Maximum Operating Depth (MOD) PO2 @ 1.4 ATA of
the gas mix being sampled
 Imperial or Metric units at a touch

Rechargeable battery powers the AII-4001 for 16 hours of continuous use.
 9 VDC power adapter 110/220 VAC is included, charges battery in 2 hours
 The adapter can safely remain connected for bench top operation
 Optional 9 VDC cigarette lighter adapter is available

Automatically conserves and protects battery life.
 The backlight turns off after 30 seconds and
 The AII-4001 completely powers itself off after 15 minutes of non-use
 The automatic turn-off features are disabled when externally powered
 The analyzer turns off 2-3 hours after the LOW BATTERY warning is displayed
to prevent complete discharge and permanent damage to the battery

The AII-4001 and accessories are packaged in a rugged waterproof plastic enclosure de­signed specifically for hostile diving conditions. The unmistakable bright red color stands
out in the shop, on the boat or in the water.
