Page 4: Preface
Preface The AMI series of analyzers provide the latest in high-definition oxygen analysis. The series includes trace (ppm) and percent models in several configurations. All of them share the same basic design approach, using AMI-manufactured oxygen sensors and advanced high definition electronics for noise and interference free performance. Several aspects of the design are the subject of patents, number 5,728,289 and 6,675,629;... -

Model 2001LC Series Oxygen Analyzer Introduction The Advanced Micro Instrument Oxygen Analyzer Model 2001LC provides the latest in low-cost high precision oxygen measurement. It is designed for monitoring oxygen in trace (ppm) ranges in a non-hazardous area. This manual covers software version 1.0. -
Page 6: Oxygen Sensor
The span calibration may be performed using standard span gases or ambient air. Unlike competitive sensors, the AMI sensor is made using a high capacity metallic body that provides long life with about twice the active ingredients of conventional sensors, but with much faster come-down times –... -
Page 7: Installation And Operation
The sensor will become saturated with oxygen by exposure to air for more than a minute or so, and once it is saturated, it may take many hours or even weeks to return to a stable low reading. Installation and Operation 4 AMI Analyzer Manual... -
Page 8: Installation Procedure
Installation Procedure Figure 1. Back panel of 2001LC analyzer Don’t open the T-2 or T-4 Oxygen Sensor bag until step 20 of this procedure!!! 1. Mount analyzer at a convenient eye level. 2. Confirm sample pressure is less than the analyzer specification (100psig). If it is higher, use a suitable regulator which must have a stainless steel diaphragm. - Page 9 If the span gas reads worse than 15% wrong, something is wrong either with the gas, or with the plumbing (you have a leak) or some other error. See the troubleshooting section for some ideas about curing this. Installation Procedure 6 AMI Analyzer Manual...

¼” vent to terminate a little way inside this larger line without sealing it. The scavenging system will then draw in room air along with the sample, while leaving the exhaust at atmospheric pressure. Installation Procedure 7 AMI Analyzer Manual... -
Page 11: Interconnections
Power connections: The 2001LC is designed to be operated from a 24V power supply only. Use a suitable wall adapter, or other kind of stable DC power supply. Make sure the ground is connected to a real ground – otherwise you may experience excessive noise and RFI interference. -
Page 12: Sample Handling
Cell block 2001LC Figure 4 Flow Schematic of the 2001LC The analyzer expects to get a sample of gas at a pressure between 1 and 100psig. A built-in needle valve and flowmeter allow the user to control flow to 1SCFH with any pressure within this range. -
Page 13: Operation
A typical way of doing this is to have the scavenging system suck on a 1” pipe, and have the ¼” exhaust line from the analyzer extend six inches or so into the end of the pipe. Installation Procedure 10 AMI Analyzer Manual... -

Page 16: Output Ranges
If the output range does not change, the security level must be set to full or span only security. In this case change the security level with the laptop and the AMI User Interface program. Alarm Set Points The alarm set points can be viewed and changed from the front panel. -
Page 17: Alarm Bypass
Values outside this range will damage the sensor. Alarm Functionality: The model 2001LC series has two alarms, with two associated relays. Normally, these are set to operate as high alarms (they go into alarm if the oxygen level goes above the set point), and to close their associated relays upon alarm. -
Page 18: Maintenance And Troubleshooting
Maintenance and troubleshooting Maintenance: The model 2001LC is virtually maintenance free other than for periodic calibration and occasional sensor replacement. Periodic Calibration: The analyzer should be calibrated about once every month to obtain the best accuracy. The sensor typically declines in sensitivity by about 1% per month, so a monthly calibration is usually satisfactory. -
Page 19: Sensor Replacement Cautions
Sensors usually contain lead which is toxic, and should generally not be thrown into ordinary trash. Refer to the MSDS to learn about potential hazards and corrective actions in case of any accident.
