Page 8: Installation Instructions
Installation Instructions for DF Battery Air Samplers The 75 LPM DF Battery Emergency Response Air Sampling System has been shipped in a corrugated box(es). Open each container, remove the air sampler from the shipping container and perform the following inspections: Confirm that the instrument calibration documentation arrived with the unit.
Page 9: Operating Features And Instructions
OPERATING FEATURES and INSTRUCTIONS The 75 LPM DF Battery Series air samplers have all the operational components conveniently accessible to the user. Model DF-75L-AC and DF-75L-Li air sampler’s pertinent components are illustrated below in Figure 1 through Figure 3. RS 232 Port...
Page 10: Operating Features And Instructions
OPERATING FEATURES and INSTRUCTIONS (Cont.) POWER SOURCE The 75 LPM DF Battery air samplers can be powered from any of the following power sources: 1. A 110VAC or 230VAC line power via the three-prong electrical connector at the rear of the enclosure.
Page 11 OPERATING FEATURES and INSTRUCTIONS (Cont.) The Digital Flowmeter: The Digital Flowmeter (DFM) is the control panel of the air sampler. Through the DFM, the operator activates the features of the instrument, as well as monitor the flow parameters. The keypad for the DFM series of air samplers has the following features: 1.
Page 12 OPERATING FEATURES and INSTRUCTIONS (Cont.) Keypad Buttons and Their Functions ON-OFF: The ON-OFF button is located in the upper right corner of the DFM module. Pressing the ON-OFF button while the air sampler is connected to line power but not running will place the unit in standby mode. Power is enabled to the DFM.
Page 13: Sensors
OPERATING FEATURES and INSTRUCTIONS (Cont.) In Time display mode, the colon (:) blinks when the motor is turned on and is continuously illuminated when the air sampler is in stand-by condition. The blinking colon also indicates that the elapsed time accumulation is in progress.
Page 14 RS232 Communications Port General Most models of the Digital Flowmeter have the RS232 communications port enabled. The DFM transmits a fixed length, comma delimited ASCII string of data. The data string is comprised of the following parameters in its general format. dd.hh.mm,ttt.t.F,bb.bb.In Hg, dd.dd In H O (aaaaaaaaa or ccccccccc), uuuuu, [….],vvvvvvvvv,UUU...
Page 15 Serial Data Utilization Any device that can accept serial data through a communications port can receive the data and store it automatically as a text string that can ultimately be imported to a spreadsheet or database. The part number for this Data Storage Device is 232FCDSD. The 1 GB Secure Digital Card part number is 372239, and the PC Flash Card Reader part number is 515177.
Page 16 Setup Enabled Features The DFM may have one or more optional features enabled. These features are only enabled at the factory when the customer purchases the feature. Note: Because of LED dimming, press the SET button twice to advance to each feature. Pressing the Set button once brightens the LEDs.
Page 17 Fl.C.3 Y or N appears on the display. (Fl.C.3 for DF-75L-12 and DF-75L-Li) 1. Press the UNITS or RESET buttons to change from Y to N. A Y enables flow control. An N disables flow control, and the motor runs at maximum.
Page 18 OPERATING FEATURES and INSTRUCTIONS (Cont.) Operating Instructions Starting and Stopping an Air Sample Event Starting a New Air Sample Event 1. If the air sampler is not already on, press the ON-OFF button. 2. Press the UNITS button to view the elapsed time value and total volume value to ensure that these values are zero.
Page 19: Filter Holders
FILTER HOLDERS The 75 LPM DF Battery Series Air Samplers accepts a standard F&J plastic combination filter holder. Filter holders are available for F&J Model B, Model C and Model M radioiodine adsorption cartridges in combination with either 47mm or 2.0-inch diameter particulate filter paper. The F&J combination filter holders have dual O-Rings and/or gaskets to ensure that the entire airflow path is through the filter cartridge and not around it.
Page 20: Sensors
SENSORS FLOW SENSOR: The Digital Flowmeter Battery Series Air Samplers com equipped with a precision-machined differential pressure sensor. The relationship of the differential pressure across the sensor as a function of flowrate is stored in the microprocessor and utilized as the starting value to determine the flowrate and totalized volume corrected to a reference temperature and pressure.
Page 21 CORRECTIONS TO A REFERENCE TEMPERATURE AND PRESSURE FLOW RATES: The differential pressure measurements of the differential flow sensor as a function of flow rate are determined during the calibration process and stored in the system microprocessor. The calculated flow rate value at the pressure and temperature conditions of the field flow measurements (often referred to as actual flow) is determined and subsequently corrected to a reference temperature and pressure condition that has been set at the factory.
Page 22: Low Voltage Limiting System Description
F&J SPECIALTY PRODUCTS, INC. The Nucleus of Quality Air Monitoring Programs Low Voltage Limiting System Description The F&J battery powered air sampler has a battery low voltage limiting system installed, which will prevent complete discharge of the battery. The low voltage limiting circuitry promotes longer battery life and increases the number of charging cycles.
Page 23 F&J recommends the utilization of either its CD-812-1 (110VAC) or CD-812E-1 (230VAC) 1% accuracy Digital Airflow Calibrator as the reference flow device for the DF-75L-12 and DF-75L-Li. The Compact Digital Calibrator has a moveable flow sensor to facilitate calibration in the field.
Page 24: Calibration Instructions
CALIBRATION INSTRUCTIONS The adaptor secures to the air sampler with a quick connect fitting and to the calibrator with the attached tubing. During the verification, the adaptor replaces the filter holder. NOTE: Be sure to insert the proper filter media into the air sampler adaptor prior to attaching the adaptor to the air sampler.
