Page 7: Description
2000 Pump is an advanced programmable sample pump ® that combines lightweight compact design, computer-compatible circuitry, and a patented* isothermal flow sensor. AirChek 2000 can be used with optional DataTrac 2000 Software and your PC to expand pump programmability and ®... -
Page 8: Performance Profile
Performance Profile Flow Range: 1000 to 3250 ml/min (5 to 500 ml/min requires low flow accessories. See Accessories.) Flow Control: An internal isothermal flow sensor measures flow directly and continuously. Sensor readings are used in a flow monitoring algorithm to maintain calibrated volumetric flow. - Page 9 Performance Profile Sample Time (SГ) AirChek 2000 sample time can be set up to 999 minutes Setting: from the pump keypad or up to 43,200 minutes (30 days) from a PC using DataTrac 2000 Software. During sampling, the pump LCD will display remaining run time (will count time down from a set number of minutes) when sample time is set from the keypad.
- Page 10 Table 1. AirChek 2000 Run Time in Hours with NiCad Battery Following are typical run times achieved when using a fully charged nickel- cadmium (NiCad) battery pack. Data is sorted by type of sample media. All run times are listed in hours. Results obtained using a new pump and new fully charged battery.

Use only an SKC-approved charger and battery pack designed for the AirChek 2000 Sample Pump to ensure reliable performance. Failure to do so voids any warranty and the UL Listing for intrinsic safety. Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety and any warranty. -

Page 23: Operation
Operation Flow Rate and Volume Display Flow rate displayed on the pump LCD is the flow to which the pump has been calibrated. To maintain flow as displayed, the pump automatically adjusts flow during sampling for changes in temperature and atmospheric pressure* that may differ from the temperature and atmospheric pressure present at the time of calibration. -
Page 24: Set/Calibrate Flow Rate (Calchek Single-Point)
The CalChek automatic calibration feature is available when calibrating an AirChek 2000 Pump with a Defender Calibrator. A CalChek Communication Cable (Cat. No. 210-502) is required. Optional DataTrac 2000 Software can be used to expand the documentation capabilities of this system. The CalChek feature provides two calibration options: single-point calibration allows setting and verifying a flow rate at a single point before and after sampling. - Page 25 Press the right arrow to highlight Preferences; press Enter. d.

Page 26: Set Up/Sample (Constant Flow)
Operation Set Up/Sample (Constant Flow) • Protect sample pump from weather when in use outdoors. • Allow pump to equilibrate after moving it from one temperature extreme to another. • Use of any device other than the approved battery pack to power the pump voids the UL Listing for intrinsic safety and any warranty. - Page 27 Operation Pump Flow Rate Ensure that battery is fully charged and that pump has run for 5 minutes before calibrating. Prepare the calibrator (see calibrator instructions). Using flexible tubing, connect the calibrator outlet (suction port) to the pump inlet. With the pump in Hold, set the pump flow rate to 1.5 L/min as follows: a.

Page 28: Set Up/Sample With Single Tube
Operation Set Up/Sample with Single Tube • Allow pump to equilibrate after moving it from one temperature extreme to another. • Charge pump battery completely before calibration and sampling. • Protect sample pump from weather when sampling outdoors. • Calibrate/verify pump flow rate before and after each sampling operation using the tube holder and pump to be used for sampling. -
Page 29: Set/Calibrate Flow Rate For Multiple Tubes
Operation Set/Calibrate Flow Rate for Multiple Tubes • Requires Constant Pressure Controller (CPC) and Dual, Tri, or Quad Adjustable Low Flow Tube Holder (see Accessories). The low flow tube holder used with CPC allows up to four tube samples to be taken simultaneously, each at different flow rates if desired. -
Page 30: Set Up/Sample With Multiple Tubes
Operation From Hold, press [] to run the pump. Loosen and turn the brass flow adjust screw directly beneath the port holding the first active tube to be calibrated (clockwise to increase, counterclockwise to decrease) until the calibrator indicates the method-specified flow rate. Do not adjust the flow rate on the pump. -
Page 31: Maintenance
Full Calibration (CalChek Multiple-point) This type of calibration provides flow correction across the basic operating range of the AirChek 2000 pump (750 to 3000 ml/min) in approximately four minutes. The operation calibrates each flow rate to a calibrator. It can also provide a record of calibration for maintenance and quality purposes if DataTrac 2000 Software is used. - Page 32 Maintenance CS1, and a brief flow rate. The pump will continue to display CS2, then a flow rate, CS3, then a flow rate, etc. until calibration is completed at all flow rates between 750 and 3000 ml/min. Full calibration begins at flows lower than 750 ml/min. At these lower flow rates, the calibrator piston will move slowly.
