Operation with Sorbent Tube
Setting the Sampling Rate
1.
Using a screwdriver, remove the metal plate on the front of the pump.
2.
The dial with an arbitrary scale is used to set the sampling rate.
Turning the dial clockwise increases the sampling rate, turning it counterclockwise decreases it.
3.
Adjust the dial to the desired position. Select the minimum setting
(position #0 on the dial) for sampling rates at the low end of the pump's flow range. Select the maximum setting (position #10) for sampling rates at the high end of the pump's flow range.
Operation Using a Stroke Counter
1.
Record the initial counter reading.
2.
Break open the ends of a sample tube.
3.
Using flexible tubing, connect the inlet of the pump to the outlet of the sample tube.
4.
Turn the pump on, using the on/off switch next to the counter, and sample for the desired time period.
5.
When finished sampling, turn the pump off.
6.
Disconnect and seal the sample tube.
7.
Record the final counter reading and calculate the air volume using the following equation. To determine the pump factor, see page 4.

Measuring Flow Rate with a Calibrator
1.
Using flexible tubing, attach the outlet of a representative sample tube to the pump inlet.
2.
Attach the inlet of the sample tube to a film flowmeter or electronic calibrator.
3.
Turn the pump on, using the on/off switch next to the counter, and measure the flow rate following the calibrator instructions.
Adjust the flow by using a screwdriver to turn the dial clockwise to increase or counterclockwise to decrease flow.
4.
When ready to sample, break the ends off a new tube, insert the tube into the tubing, and sample for the desired sampling period.
Protect sample pump from weather when in use outdoors.
