User Interface Level One
Both the pre-calibration and post-calibration flow rates with the time and date are recorded in the pump history
memory and can be accessed using the optional DataTrac Interface and Software and a PC.
The single point calibration function can also be used to provide an automatic post sampling calibration check.
However, as the function may adjust the flow rate, this is only recommended if the DataTrac Interface and
Software are available. Otherwise a manual post sampling calibration check is recommended.
3) Full (Multiple Point) Flow Calibration Using CalChek
This type of automatic calibration provides flow correction across the operating range of the AirChek 3000
pump in approximately 4 minutes. The operation calibrates each flow rate to a Defender primary standard. It
can also provide a record of calibration for maintenance and quality purposes if the optional DataTrac Interface
and Software is used. SKC recommends that a full calibration be performed during pump maintenance and
after non-factory repairs.
Note:
• Full calibration clears the pump history, run time parameters, and the Scheduler in the DataTrac Software.
• Ensure that the battery pack is fully charged before starting a full calibration.
• Do not perform a full calibration until the pump has remained at ambient temperature for at least 2 hours.
• Full calibration is carried out with no sample media in line.
1. Connect the Defender primary flow calibrator air outlet port directly to the pump air inlet port. Connect
the CalChek Communicator cable between the serial interface (RS-232) port on the rear of the Defender
primary calibrator and the PC interface socket on the rear of the AirChek 3000 pump.
2. With the pump in HOLD mode, press [ ] to switch to RUN mode, and allow the pump to run for at
least 5 minutes before commencing full calibration.
