Run Time Data Screens
The flow rate displayed on the pump LCD screen is the flow rate to which the pump has been calibrated. To
maintain the flow rate as displayed, the pump automatically adjusts its operation during sampling for changes
in temperature and atmospheric pressure that may differ from the temperature and atmospheric pressure
present at the time of calibration. The flow rate display does not change from the calibrated flow rate. The
pump will flow fault if it is unable to maintain the calibrated flow rate to within ±5 %.
The accumulated sample air volume displayed on the pump LCD screen is ”corrected” in that it is the result of
a continuous calculation of corrected flow rate multiplied by sample time.
