Manual
Calibration
1. Ensure pump had run for 5 minutes before calibrating.
2. Using fl exible tubing, connect the outlet of the
Bu on Sampler to the inlet of a sampling pump.
3. Place the calibration adapter outlet onto the Bu on
Sampler inlet, and connect the calibration adapter
inlet to a primary standard calibrator.
4. Calibrate to 4 L/min following the instructions in the
pump and calibrator operating instructions.
5. Disconnect the calibrator and calibration adapter.
Replace the fi lter used to set the fl ow with a fresh
conditioned and weighed fi lter for sample collection.
Note: If using the Bu on Sampler with protective shield for abrasive blasting
sampling, calibrate the Bu on Sampler without shield using the Calibration
Adapter. Following calibration, push shield onto sampler inlet and sample.
Sampling
1. Ensure the fl ow rate has been calibrated (see Calibration).
2. Using fl exible tubing, connect the outlet of the Bu on Sampler to the inlet of
a sampling pump such as an AirChek
®
XR5000 Sampler.
3. For personal sampling, clip the Bu on Sampler onto a worker’s collar or
pocket near the breathing zone. Clip the pump onto the worker’s belt or
place it in a protective pouch. Start the pump and record the start time,
worker location, and fl ow rate.

Operation
Wear gloves and use forceps when handling fi lters.
1. For gravimetric sampling, condition and weigh a 25-mm fi lter according to
method used.
2. Unscrew the inlet of the sampler counterclockwise until it comes off and
remove the PTFE O-ring.
3. Place the 25-mm fi lter on top of the support screen inside the sampler.
Note: Representative fi lters used for calibration do not require conditioning and
weighing.
4. Place the PTFE O-ring on top of the fi lter.
5. Replace the inlet and very gently turn clockwise until moderately tight.
Caution: Excessive tightening of the inlet section can twist and tear the fi lter.
