Site Setup; Verification/Calibration; Instrument Verification - Teledyne T640 Standard Operating Procedure

vertical line from the TSP inlet to the inlet of the Aerosol Sample Conditioner (ASC). Other
siting specifications are set forth in the FDEP PM2.5 Quality Assurance Project Plan, Rev.3:
05-12 and Title 40 of the Code of Federal Regulations (CFR), Part 58, Appendices D and E,
which must also be adhered to.
To satisfy these requirements, individual installations of the Teledyne Model T640 monitoring
system may vary depending on available site locations and shelter layout. The manufacturer's
manual gives both general and detailed specifications for installation of the monitor and must be
followed where practical.
The hardware and software configurations must be completed before the T640 collects any
ambient data.

9.1.1 Site Setup

The T640 may be installed either in a monitoring shelter that contains existing monitoring
equipment or in a separate outdoor enclosure.
The T640's acceptable shelter temperature range is 0 to 50º C. However, operating ambient air
instruments at 25ºC or lower can create large moisture issues during the summer because of the
presence of high ambient humidity. These issues must be satisfactorily addressed before
installing a T640 in an enclosure.
The shelter must be equipped with a wireless modem. This connection allows the operator to
remotely communicate with the TEOM via the manufacturer supplied computer software
Numaview, or other compatible software package.
The shelter/enclosure must also have a NIST Traceable Min/Max thermometer and be calibrated
annually by a NIST reference thermometer to verify operating temperatures within the
enclosure.

10.0 VERIFICATION/CALIBRATION

This section details the verification/calibration procedures periodically required to maintain
accurate particulate sampling of the T640.

10.1 Instrument Verification

There are five basic verification checks and three calibrations. There is no adjustment for either
the zero test or ambient temperature and as such failure of one or both checks results in the need
to troubleshoot rather than adjust a setting. The verifications/calibrations should always be
performed in a specific order as shown below:
1. Zero Test;
2. Pressure sensor verification;
3. Temperature sensor verification;
4. Flow sensor verifications;
