Teledyne T100 Manuale Utente

  Single range selection. Refer to Section 5.4.3.1 of this manual. If the instrument will 

be used on more than one range, it should be calibrated separately on each 
applicable range. 

  Automatic temperature/pressure compensation should be enabled. Refer to Section 

  Alternate units: ensure that the ppb units are selected for EPA monitoring. Refer to 

Section 5.4.4. 

The analyzer should be calibrated on the same range used for monitoring. If the AUTO 
range mode is selected, the highest of the ranges will result in the most accurate 
calibration, and should be used. 

To perform a precision calibration, the instrument set up; input sources of zero air and 
sample gas and; procedures should conform to those described in Section 9.2 for 
analyzers with no valve options or IZS valve option installed and Section 9.5 for 
analyzers with IZS options installed with the following exception: 

A periodic check is used to assess the data for precision. A one-point precision check 
must be carried out at least once every 2 weeks on each analyzer at an SO

2

 concentration 

between 0.08 and 0.10 ppm. The analyzer must be operated in its normal sampling 
mode, and the precision test gas must pass through all filters, scrubbers, conditioners, 
and other components used during normal ambient sampling. The standards from which 
precision check test concentrations are obtained must be traceable to NIST-SRM. Those 
standards used for calibration or auditing may be used. 

To perform a precision check, the instrument setup; sources of zero air and sample gas 
and procedures should conform to those described in Section 9.1.1 for analyzers with no 
valve options or IZS valve option installed and Section 9.6 for analyzers with Z/S or IZS 
options installed with the following exception: 

Connect the analyzer to a precision gas that has an SO

2

 concentration between 0.08 and 

0.10 ppm. If a precision check is made in conjunction with a zero/span check, it must be 
made prior to any zero or span adjustments. 

Record this value. Information from the check procedure is used to assess the precision 
of the monitoring data; refer to 40 CFR 58 for procedures for calculating and reporting 
precision.
