    Flow Rate indicated is a coarse approximation and is somewhere 10% of that displayed. Use the Calibration Mode to set this to 2%. During the initial time that the PQ100 requires to stabilize its flow rate, flow will be displayed as --.-Lpm.

  • Page 24: 6.8.4 Acoustic Phenomena At High Negative Pressure

    6.8.4 Acoustic Phenomena at High Negative Pressure When running the PQ100 at very high load pressures (i.e. 150 centimeters of water or better), a metal popping sound may be heard by the user. This is merely the internal pulsation dampner (Plenum) adjusting its chamber area. The PQ100 will alert you as to the nature of any problems via the shutdown messages as described in APPENDIX E.

    IDLE DISPLAY AND PRESS "RUN/STOP". BE CERTAIN THAT THE START DATE ENABLE IS SET TO "OFF" (SECTION 6.9). This mode is used to Calibrate the PQ100 at a target flow rate. It should be noted here that each individual target has it's own independent calibration storage area and is non-volatile.

  • Page 26: Using A Deltacal Or Trical

    The use of a DeltaCal or TetraCal (formally triCal) is highly recommended for calibration of the PQ100. Connect either unit to the PQ100 just before the filter holder and read the actual flow on the display. More information on the DeltaCal or TetraCal (formally triCal) may be found at www.bgiusa.com/cal/index.htm...

  • Page 27: Using A Rotameter

    Using a Rotameter Calibrating the PQ100 Air Sampler with a Rotameter is to be avoided for two reasons. The PQ100 is more accurate (.5% of the expected flow rate) than the typical rotameter (within 3% of Full Scale). Secondly, the rotameter, unlike the bubble meter, has a reference condition calibration and requires a correction for ambient conditions.

  • Page 28: Calibration Notes

    Lpm. That means 9.66 Lpm could actually vary from 9.06 to 10.26 Lpm! Therefore, if a rotameter must be used with the PQ100, the corrections are pointless and a straight 10 Lpm read from the rotameter should be utilized. The accuracy of the PQ100 is now degraded to 5%.

  • Page 29: Installation And Use Of The Pc Software

    INSTALLATION AND USE OF THE PC SOFTWARE Supported Hardware Any IBM PC or compatible running MS-DOS 2.1 or higher with 1 floppy drive and at least 512K of memory. Any video adapter, Color or Monochrome, may be used. A hard drive is useful but not required.

  • Page 30: Running The Program

    PQ allows the user to communicate with the PQ100 Air Sampler and downloads Run Data from the PQ100 to your PC. The data may then at a later time be appended with the measured final filter weight, printed and stored for later use.

  • Page 31: Beginning A Sample Job

    When a sample job has been completed, the data pertaining to the run is stored in the PQ100 until it is reset by the user. Prior to resetting the PQ100 for its next run, the data should be downloaded using the PQ software to provide information such as run time, total sample accumulated, cause of the shutdown etc.

  • Page 32: Adding The Final Filter Weight

    8.10 Adding the Final Filter Weight Upon completion of the sample job, the final filter weight must be determined and this final weight entered in order to compute concentration. From the PQ Main Menu press "a" to Add the final filter weight. Again you are asked for the appropriate file name and again you must be careful to select the proper file.

This is used to combine a number of run files into a multi record database with each job file as a record. For a more detailed description of the use of this type of file refer to the users manual of your database program.

  • Page 34: Ac Power Supply/Charger

    The PQ100 should be Recharged before use to allow for the greatest available Run Time. Connect the Charger to the PQ100 Utility Adapter socket located on the front panel. Plug the Charger into an appropriate power source. BE SURE TO CHECK CHARGER SPECIFICATIONS FOR CORRECT POWER SOURCE INPUT.

    To determine "Pump Cumulative Time" you must use the PQ software to obtain a download from the PQ100 (See Section 8.9). Pump Cumulative time is the number of actual service hours of the dual diaphragm pump and is shown when either printing or screen viewing a download.

  • Page 38: Replacement Of The Mass Flow Sensor

    10.3 Replacement of the Mass Flow Sensor As each mass flow sensor is unique and will present variations in operation, all stored calibrations are obsolete when the sensor is replaced. Each flow sensor replacement kit contains an 8 pin DIP Integrated Circuit (I.C.) that must be replaced (socketed) on the main printed circuit board.

When applying these instructions to the PQ100, the following steps are suggested: Place a clean filter of the type to be used for the sampling in the PQ100 filter holder. Remove the PM10 inlet and connect a bubble meter to the filter holder. BGI adaptor (P/N L-30) is convenient for this purpose.

  • Page 53: Appendix J. Flow Rate Stability

    The initial flow rate is measured one minute after the instrument has stabilized the flow rate (The flow rate is stable when the PQ100 visual display shows the actual flow rate instead of "Q--.-"). The flow rate is then sampled once every hour thereafter until the completion of the run with a maximum capability of 30 readings after the initial.
  • Page 54 In reality all displayed values should be expected to be typically less than 1% and should not exceed 2%. Values more than 2% should be investigated. A blocked or restricted inlet, hose, etc. at precisely the time the PQ100 takes a reading internally should be suspected.

SOLAR PANEL POWER SUPPLY Introduction The SP32, solar panel kit is intended to permit the PQ100 to run for extended or, indefinite periods of time depending on the available sunlight (solar radiation) at a given location. The solar panel may only be used as the sole source of power for a U.S. EPA-designated instrument if sampling is not being performed every day (i.e., continuously).
