The 9705 is not flow rate independent. It has been calibrated to a specific flow rate. To operate
the 9705 at a different flow rate, calibrate the 9705 to that specific flow rate. PharmSpec will
store multiple calibration curves for this purpose.
CAUTION:
If the flow rate is set to a value other than the rate corresponding to the calibration curve, the
system response may be inaccurate.
