Operation

Calibration

1. Prepare a cyclone/cassett e assembly (Figure 1). Ensure grit pot remains on
cyclone body during calibration.
SKC recommends using the smallest calibration jar possible. To achieve this, do
NOT use Cassette Holder Cat. No. 225-1 during calibration.
2. Place cyclone/cassett e assembly into an airtight calibration jar that contains an
inlet and outlet (Cat. No. 225-111, Figure 3).
3. Using fl exible tubing, connect outlet of calibrator to inlet of calibration jar.
4. Run tubing from outlet of cyclone/cassett e assembly through the outlet of the
calibration jar and to the inlet of a sample pump. If using the Calibration Jar
(Cat. No. 225-111), connect the Luer adapter inside the jar lid to the cassett e
outlet. Connect jar outlet tubing to the sample pump inlet.

5. Turn on pump and calibrate to desired fl ow rate following directions in the
pump and calibrator operating instructions.
Flow rate:
* Calibrated at U.K. Health and Safety Laboratories. Visit www.skcinc.com/prod/225-100.asp to view the
collection effi ciency curve.
6. After calibration, disassemble calibration jar, remove cyclone/cassett e assembly,
and replace cassett e used for calibration with a fresh (unused) cassett e to be
used for sampling.
