Preface
The AMI story
The AMI series of analyzers pro ide the latest in high-definition oxygen analysis. The series includes trace
(ppm) and percent models in se eral configurations. All of them share the same basic design approach,
using AMI-manufactured oxygen sensors and ad anced high definition electronics for noise and interference
free performance. Se eral aspects of the design are the subject of patents, number 5,728,289 and
6,675,629; the sensors are also co ered by a patent, number 7,316,768.
Please erify that the analyzer was not damaged in transit. If so please contact the shipper as well as AMI.
Caution
Read and understand this manual fully before attempting to use the instrument. In particular understand
the hazards associated with using flammable or poisonous gases.

Oxygen sensor:
AMI manufactures its own electrochemical sensor. This measures the concentration of oxygen in a gas
stream, using an oxygen specific chemistry. It generates an output current in proportion to the amount of
oxygen present, and has zero output in the absence of oxygen, thus a oiding any requirement to zero the
analyzer. The cell is linear throughout its range. The span calibration may be performed using standard
span gases or ambient air. Unlike competiti e sensors, the AMI sensor is made using a high capacity metallic
body that pro ides long life with about twice the acti e ingredients of con entional sensors.
Sensor Warranty:
The sensor is warranted to operate for a period determined by its class. If the sensor ceases to operate
correctly before this time has elapsed, contact AMI for a return authorization for e aluation. If there is any
e idence of defecti e material or workmanship the sensor will be replaced free of charge.
NOTE: Any e idence of abuse or physical damage, such as a torn membrane, will oid the warranty.
Instrument Warranty:
Any failure of material or workmanship will be repaired free of charge for a period of two years from the
original purchase (shipping date) of the instrument. AMI will also pay for one way shipment (back to the
user).
This warranty does not co er the sensor, which is co ered by its own warranty (see abo e).
Any indication of abuse or tampering will oid the warranty.
Receiving the analyzer
When you recei e the instrument, check the package for e idence of damage and if any is found, contact the
shipper.

Important:
This section contains important information to do with safety and installation. Please don’t skip it!
-------------------------Points to consider first! ------------------------------
Environment – what is the temperature range going to be where the analyzer will be installed? If the
temperature is going to go below freezing, you will need a heated ersion or to place it in a temperature
controlled building. Also, make sure it won’t get too hot in the summer – you may need to entilate or e en
air condition a building. The standard (non-heated) temperature specification is 25ºF to 115°F.
Sample conditions – if your sample is hot and wet, you will need to keep water from condensing in the
sample line or analyzer. Contact AMI for ad ice. If the sample contains high amounts of CO2, it will be
necessary to temperature control the analyzer so that the sensor doesn’t explode like a can of soda on your
car’s dashboard in summer. Contact AMI for this one too.
Sample pressure – this analyzer is designed to work with ambient pressure samples, such as that from a
glo e box. As a result it draw the sample from the source through the sample line and then onto the sensor.
The pressure drop across this line must be minimal – 1psig at the absolute most. If the line is long, use 3/8”
or wider tubing.
Power supply – The unit contains a switching power supply that is insensiti e to AC oltage or frequency
changes o er a wide range. It will work with any normal UPS system if desired.
Electrical connections - Following best electrical practices, run the analog output connections separately
from the power and alarm connections. Modbus communications if used should be run with the analog
output wiring, using twisted pair wires for both circuits. Run the alarm wires in the same conduit as the
power wires.
Solenoid valves – if the analyzer is going to be used to control gas flow (such as to shut in contaminated gas)
using solenoid al es, consider using latching type al es and the analyzer pulse feature so as to minimize
power consumption, particularly if you are using a battery and in erter as the power supply. Standard
solenoid al es require power to remain open (or closed), whereas latching al es require power only when
changing their position. This conser es a lot of power.
Span gas –It is strongly suggested that you use room air to calibrate this unit. If you are going to use span
gas to calibrate the analyzer as opposed to air, you will need to plumb a span gas tank to the span inlet on
the back of the analyzer. When you do this, the line to the tank will be full of air. When you subsequently
span the analyzer, oxygen from the air will ha e leaked into the span line potentially increasing its oxygen
content. Wait until the reading has stabilized, and then adjust the span.

In addition, since the analyzer includes a pump, you have to take care that you do not pressurize the
sensor with the span gas. It will be necessary to use a bypass valve and flow meter on the span inlet of
the analyzer.

Receiving the analyzer
When you recei e the instrument, check the package for e idence of damage and if any is found, contact the
shipper.
Installation.
Location:
The unit is designed to be mounted in a panel in a general purpose area. It should be mounted at a suitable
iewing le el. Refer to the drawing (figure 1) showing the analyzer dimensions. It is not suitable for use in a
hazardous area.
Although the unit is RFI protected, do not to mount it close to sources of electrical interference such as large
transformers, motor start contactors, relays etc. Also a oid subjecting it to excessi e ibration – anything
worse than a truck may be problematical.
