The acceptable operating flow range of a TSP sampler is 1.1 to 1.7 m3/min
(39 to 60 CFM). Looking at the worksheet (page 36) column Qstd, the flow
rates that are within this range can be identified along with the chart reading
(I) that represents them. For instance if you wanted to set this sampler at
1.265 m3/min (44.67 CFM) (Make sure the mass flow controller is plugged in
and a filter is in place) you would turn the Flow Adjustment screw until the
continuous flow recorder read 37 on the chart. By making sure that the
sampler is operating at a chart reading (or manometer reading) that is within
the acceptable range, it can be assumed that valid TSP data is being collected.
