1 Gilian Air Sampling Pump Field Calibration A Step-By-Step Guide

2 Items required Sampling Pump Collection Media Gilibrator Calibrator

3 A Field Calibration Consists of Two Parts The Pre-Calibration (Pre-Cal) is done before the sample is taken The Post-Calibration (Post Cal) is done after the sample is taken

4 The Pre-Cal The Pre-Cal is used to set the desired sample flow rate, and to verify it on an air flow calibrator.

5 Conducting the Pre-Calibration

6 The Pre-Cal Set the Flow Rate Observe the Flow Rate Record the Flow Rate An average of 6 to 10 Gilibrator readings is recommended

7 Run The Sample Pump is placed on the belt Sample media is placed on the lapel (Breathing Zone) and pointed downward Record the Start Time Record the End Time

8 The Post-Cal The Post-Cal is used to obtain the final flow rate and to verify that the flow rate stayed within +/- 5% of the set flow.

9 The Post-Cal Observe the Final Flow Rate Record the Final Flow Rate An average of 6 to 10 Gilibrator readings is recommended

10 Average Flow Rate The Pre-Cal flow rate and the Post-Cal flow rate may be averaged to obtain an average flow rate for the sample.

11 Pre-Cal Flow Rate + Post Cal Flow Rate = Avg Flow Rate 2 Determining the Average Flow Rate

12 Cyclone Calibration The Gilian 10mm nylon cyclone has only an exit fitting and must be placed inside a calibration jar to accept the Gilibrator.

13 Low Flow Modules Calibrating with low flow modules

14 Constant Flow Modules Set pump flow to 1500cc/min Turn module switch on Connect sample tubing to pump Adjust desired flow rate at module Read flow rate at Gilibrator

15 Multi-Flow Modules Set pump to 1500 cc/min Turn module switch on Connect sample tubing to pump Adjust flow rate at holder Adjust each tube twice Read the flow rates

16 Further Information For detailed information on any of the Gilian products, please consult the product operation manuals. Manuals may be accessed through our web site at www.sensidyne.com
