Option 2: Jarless Calibration - Figure 4
This calibration option is recommended when using a Defender primary standard
calibrator to calibrate personal air sample pumps for size-selective particulate sampling
using particulate samplers that do not have their own calibration adapters.
1. Use a length of fl exible tubing to att ach the inlet of the sample pump to the
suction port of a Defender calibrator.
2. Use the shortest length of tubing possible to att ach the outlet of the cassett e in
a cyclone/cassett e assembly to the pressure port of the Defender.
3. Set the Defender to take at least 20 fl ow measurements in order to average out
the fl ow variations caused by direct connection of the pump to the calibrator.
See calibrator operating instructions for details.
Sampling
Check the sampling method being used for fl ow rate and sampling media
requirements.
1. Calibrate pump to desired fl ow rate using representative sampling media (see
Calibration).
Leave grit pot in place during calibration and sampling.
