A Field Calibration Consists of TwoA Field Calibration Consists of Two PartsParts
• The Pre-Calibration (Pre-Cal) is done before the sample is taken
• The Post-Calibration (Post Cal) is done after the sample is taken
![Page 4: Gilian Air Sampling Pump Field Calibration A Step-By-Step Guide.](https://reader036.fdocuments.in/reader036/viewer/2022062307/551b0dc3550346cf5a8b4ea7/html5/thumbnails/4.jpg)
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.

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.

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.
