    The T640 has been provided with a “short temperature probe” for the purposes of operating flow calibrations as well as PMT checks inside indoor shelters. The purpose of this is for the ambient temperature measurement to match the flow device at the location of the flow standard.

  • Page 63: Ambient Temperature Sensor Check

    This kit includes fittings for adapting your flow audit device to the sample tube for either the T640 or 640x option, and also contains a filter for running a “leak check”. A picture of the kit contents are shown below: Figure 4-1.

  • Page 64: Pressure Sensor Check And Calibration

    This setting exists in the VARS menu. 1. With the NIST-traceable pressure standard reference device operating and measuring the ambient pressure in the same room as the T640, navigate to the Pressure Cal menu (Calibration>Pressure Cal). 2. Compare the “Measured Pressure” in this screen to the Pressure Standard.

    CHECKING FOR LEAKS The internal components of the T640 are not meant to be under strict vacuum as what would normally be done in a leak test. So, to avoid damage to internal components, it is recommended that the inlet never be capped (air tight) while the instrument pump is running.

    3. Remove the sample line inlet and replace with the T640 leak check kit (084910000) or equivalent fitting with filter. 4. Within a few minutes, the PM values should be at zero; note the following:  PM values remaining below 0.2ug/m3 indicate that there are no leaks.

    Technical Support Forms. PRINCIPLES OF OPERATION The Model T640 PM Mass Monitor is an optical aerosol spectrometer that converts optical measurements to mass measurements with sharp accuracy by determining sampled particle size via scattered light at the single particle level according to Lorenz-Mie Theory.

  • Page 84: Sampling System

    The flow stream is measured (main flow at 5 LPM for T640 and bypass at 11.67 for 640X Option), and a feedback loop triggers the pump drive voltage adjustments to maintain a constant flow (5 LPM in the T640, 16.67 LPM in the 640x Option).
