Classifier Calibration D–7
Figure D-6
Sheath Flow Calibration
Bypass-Air Calibration
1. Select MENU from the main screen on the front panel display
of the 3080 Electrostatic Classifier.
2. Select Flow Calibration.
3. Select Bypass Flow.
4. Set Raw Bypass Flow to OFF (0.00) LPM and wait 60 seconds
until flow has completely stopped.
5. Make sure that Exhaust Flow and Excess Flow port fittings
are connected by a tube on the outside of the Classifier.
6. Connect the Flowmeter Standard to the Sheath Flow port
fitting on the Classifier.
7. Set Bypass Flow to 2 L/min and wait for the flow to stabilize.
Take five (5) samples and average them. Record the Pressure
drop (dP) and flowmeter (Qcal) readings.
8. Repeat step 7 for 4, 6, 8, 10, 12, 14, and 16 L/min for a total
of 8 data points.
