Troubleshooting and Service 

Teledyne API – Model T300/T300M CO Analyzer 

How do I perform a leak check? 

Section 11.3.3 provides leak check instructions. 

How do I measure the sample 
flow? 

Sample flow is measured by attaching a calibrated rotameter, wet test 
meter, or other flow-measuring device to the sample inlet port when the 
instrument is operating.  The sample flow should be 800 cm

3

/min 

10%.  

See Section 11.3.4. 

How long does the IR source last?  Typical lifetime is about 2-3 years. 

Can I automate the calibration of 
my analyzer? 

Any analyzer with zero/span valve or IZS option can be automatically 
calibrated using the instrument’s AutoCal feature.  The setup of this 
option is located in Section 9.4. 

Can I use the IZS option to 
calibrate the analyzer? 

Yes.  However, whereas this may be acceptable for basic calibration 
checks, the IZS option is not permitted as a calibration source in 
applications following US EPA protocols.   

To achieve highest accuracy, it is recommended to use cylinders of 
calibrated span gases in combination with a zero air source.   

Q: What is the averaging time for 
an T300/T300M? 

A: The default averaging time, optimized for ambient pollution 
monitoring, is 150 seconds for stable concentrations and 10 seconds for 
rapidly changing concentrations (see Section 13.5.1 for more 
information).   

However, it is adjustable over a range of 0.5 second to 200 seconds 
(please contact Customer Service for more information).
