8.
Place the NIST Flow Meter on the inlet sample tube and properly zero
the flow meter.
9.
Start the calibration by pressing enter from the Flow calibration screen
while the cursor is position in front of Start Calibration.
10.
The unit should begin to bring the flow up to the first set point.
ALLOW THE FLOW TO STABILIZE FOR AT LEAST 15
MINUTES. THIS WILL ACT AS THE FLOW CONTROLLER
WARM-UP PERIOD.
11.
Perform the flow calibration as the operating manual describes, when
the measured flow is stable for each point aproximately 2-3 minutes for
each point enter the actual value as measured by your flow meter.
12.
At the end of the calibration the unit will display the calculated
intercept or offset and span values necessary to linearize the flow sensor
to the operational range.
13.
Open the filter exchange mechanism and place the flow calibration
cassette in the Fine (Back) position of the holder. Move the regular
cassette with filter media to the Coarse (Front) position of the holder.

Place the dual filter holder in the filter exchange mechanism and close
the filter exchange mechanism making sure the seals are not
compromised.
