Page 5: Purpose
PM2.5 [EQPM-0516-238] and PM10--2.5 [EQPM-0516-240], The T640 operates at a total flow 16.7 lpm and this SOP is written specifically for this method. The model T640 is an approved FEM for PM2.5 [EQPM-0516-236]. The T640 also measures PM10 and PM10-2.5, but only the... -
Page 6: Principles Of Operation
The T640 operates at 5.0 lpm with a TSP inlet. This configuration is approved as an FEM for PM2.5; however, it also provides data (not approved as an FEM) for PM10 and PM10-2.5. -

DEP 03-21 Revision No. 0 November 2017 Table 4-1 Terms and Definitions Term Definition The degree of agreement between an observed value and an accepted Accuracy reference value; includes a combination of random error (precision) and systematic error (bias) components due to sampling and analytical operations. The actual ambient temperature and pressure of a gas at the time its volume Actual conditions (or volumetric flow rate) is measured. -

Page 9: Equipment And Supplies
Since detailed information for various procedures are contained in the manufacturer’s manual, it must be on hand during any operator interaction with the Teledyne T640 monitor. 9.1 Installation For the monitor to operate within EPA guidelines, the sample inlet must be located between 2 and 15 meters above ground level. -
Page 10: 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. -
Page 11: Leak Test
5. PMT verification using SpanDust™. 10.1.1 Leak Test 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. -
Page 12: Ambient Temperature Verification
3. Record audit device ambient temperature and T640x ambient temperature to the “Monthly QC and Maintenance sheet”. 4. Compare audit to T640 ambient temperature and if off by more than +/-2C, troubleshoot and repeat. 5. If verification cannot meet tolerance replace temperature probe. -
Page 13: Pmt Verification
The Particle Sensor PMT Verification uses SpanDust™, a monodisperse dust with a specific refractive index. All T640 instrument PMTs have a very specific response to this span dust which allows for the sensor to be checked in the field for drift caused by contamination of the... -

2. Press the Start button on this screen to suspend normal data acquisition and start this adjustment process. 3. Remove the T640 sample inlet. 4. Prepare the SpanDust™ bottle by uncapping the “air intake” tubing on the cap of the bottle. -
Page 15: Pressure Sensor Calibration
November 2017 10.2.1 Pressure Sensor Calibration The pressure measurement of the T640 is for the ambient pressure in which the instrument is operated. No direct pneumatic connection to the instrument needs to be made to perform this calibration and data are not affected. -
Page 16: Pmt Adjustment
The Particle Sensor PMT Calibration uses SpanDust™, a monodisperse dust with a specific refractive index. All T640 instrument PMTs have a very specific response to this span dust which allows for the sensor to be adjusted in the field for drift caused by contamination of the optics. -

11. Reattach the sample inlet and press the Stop button to stop the adjustment process and resume normal data acquisition. For more information on the PMT Adjustment, use the QR above to view a video by Teledyne API. 12. Wait 10 minutes, review data on home screen of T640x, and then bring unit back “On Scan”... -

Page 19: Changing The Disposable Filter Unit (Dfu)
This procedure should be repeated per the schedule in Table 6-1. 11.2 Changing the Disposable Filter Unit (DFU) There is one DFU on the T640 for the 5.0 lpm pump 1. Power off the internal pump from the control menu: Setup> Vars> Pump > Edit> Off... -

DEP 03-21 Revision No. 0 November 2017 2. Remove screws at sides of front panel, if installed. 3. Pull open the instrument’s front panel, using the front panel finger grips (Figure 7) Figure 8 Opening the Front Panel 4. Noting its orientation, remove the old DFU by detaching from the pneumatic quick- connect fittings, and replace with a new DFU matching the orientation (Figure 8). -

>Main Menu > Home >Dashboard. 11.3 Checking Pump Performance There is one pump associated with the T640 an internal (operating at 5 lpm). The 5 lpm pump must maintain proper flow for measurement accuracy. Check the performance level in the Dashboard (If the parameter is not found in the Dashboard, configure the Dashboard to add it;... -

RH/T sensor and from RH/T sensor to the DFU filter, and reinstall the ASC support. Close instrument and power back online. Perform a PMT sensor check with the SpanDust™ (Section 4.1.4 of the T640 User Manual). 11.6 Inspecting the Sample Tubes Look inside the sample tubes for debris or dust on the walls. -
