Field CalibrationField Calibration
• 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

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

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

Run The SampleRun 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

The Post-CalThe 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.

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

Average Flow RateAverage 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.

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

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