Calibration Procedures Teledyne ML - T100 UV Fluorescence SO2 Analyzer
186
IMPORTANT The CALIBRATE attribute must always be set to OFF for analyzers used in US
EPA controlled applications that have IZS option installed.
Calibration of instruments used in US EPA related applications should only be
performed using external sources of zero air and span gas with an accuracy
traceable to EPA or NIST standards and supplied through
the analyzer’s sample
port (refer to Section 6.2).
The following example sets Sequence 2 to carry out a zero-span calibration every other
day starting at 01:00 on September 4, 2002, lasting 15 minutes. This sequence will start
0.5 hours later each day.
