The following list contains some of the most commonly asked questions relating to the 
T100 SO

 Analyzer. 

Why is the ZERO or SPAN button not 
displayed during calibration? 

The T100 disables these buttons when the expected span or zero value entered by 
the users is too different from the gas concentration actually measured value at the 
time.  This is to prevent the accidental recalibration of the analyzer to an out-of-
range response curve.-EXAMPLE:  The span set point is 400 ppb but gas 
concentration being measured is only 50 ppb.-For more information, refer to Section 
12.4.4 and Section 12.4.5. 

Why does the ENTR button 
sometimes disappear on the Front 
Panel Display? 

During certain types of adjustments or configuration operations, the ENTR button 
will disappear if you select a setting that is nonsensical (such as trying to set the 24-
hour clock to 25:00:00) or out of the allowable range for that parameter (such as 
selecting a DAS hold off period of more than 20 minutes).-Once you adjust the 
setting in question to an allowable value, the ENTR button will re-appear. 

How do I enter or change the value of 
my Span Gas? 

Press the CONC button found under the CAL or CALS menus of the main SAMPLE 
menu to enter the expected SO

span concentration.-Refer to Section 3.4.4.1 or for 

more information. 

Why does the analyzer not respond to 
span gas? 

Section 12.4.4 has some possible answers to this question. 

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.-However, the accuracy of the IZS option’s 
permeation tube is ±5%. While 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. Teledyne API offers a 
zero air generator Model 701 and a gas dilution calibrator Model T700 for this 
purpose. 

What do I do if the concentration on 
the instrument's front panel display 
does not match the value recorded or 
displayed on my data logger even if 
both instruments are properly 
calibrated? 

This most commonly occurs for one of the following reasons: -A difference in circuit 
ground between the analyzer and the data logger or a wiring problem;-A scale 
problem with the input to the data logger.  -The analog outputs of the T100 can be 
manually adjusted to compensate for either or both of these effects, refer to 5.9.3.4; 
-The analog outputs are not calibrated, which can happen after a firmware upgrade.  
-Both the electronic scale and offset of the analog outputs can be adjusted (refer to 
Section 5.9.3.2).  Alternately, use the data logger itself as the metering device during 
calibrations procedures. 

How do I perform a leak check? 

Refer to Section 11.3.6. 

How do I measure the sample flow? 

Sample flow is measured by attaching a calibrated flow meter to the sample inlet 
port when the instrument is operating. The sample flow should be 650 cm³/min 
10%. Section 11.3.6 includes detailed instructions on performing a check of the 
sample gas flow. 

How often do I need to change the 
particulate filter? 

Once per week. Table 11-1 contains a maintenance schedule listing the most 
important, regular maintenance tasks. 

What is the averaging time for an 
T100? 

The default averaging time, optimized for ambient pollution monitoring, is 240 

seconds for stable concentrations and 20 seconds for rapidly changing 
concentrations; Refer to 13.7.1 for more information.   

My analyzer has the optional, user -
configurable analog output channels.  

Instructions for this can be found in the Manual Addendum for Configurable Analog 
Output, PN 06270.
