The Flow Pressure Span screen allows the user to view and set the flow
sensor calibration span point.
To calibrate the flow pressure sensor span point, the instrument must be
pulling an active flow through the filter tape. By use of a manometer,
connect the resp/- ports of your NIST-traceable manometer to the
respective rear panel +/- ports. (Please be certain to zero any digital
manometers prior to connecting!) Open the ports by pressing the toggle
switches inward. Calculate an average reading from the reference
manometer in units of mmHg. Enter this span value into the screen below:
