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
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.
ConductingConducting the Pre-Calibrationthe Pre-Calibration
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.
Pre-Cal Flow Rate + Post Cal Flow RatePre-Cal Flow Rate + Post Cal Flow Rate = = Avg Flow RateAvg Flow Rate 2 2
• Determining the Average Flow Rate
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.
Low Flow ModulesLow Flow Modules
• Calibrating with low flow modules
Constant Flow ModulesConstant 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
Multi-Flow ModulesMulti-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
