Record the information required for data computation and quality
assurance purposes. At a minimum, this would usually include the
volume sampled (Vol), the flow rate coefficient of variation (%CV), the
total sampling time (Tot), the largest difference between the ambient
and filter temperatures (Delta T), and the status code (Stat).
Note
The information contained in the Filter Data, Interval Data, and
User Data may be downloaded from the Sampler using a USB memory
stick or onto personal computer (PC) using software and a cable provided
with the Sampler.

Note
Collection filters should be transported carefully in the metal/anti-
static transport containers provided with the Sampler to and from the
sampling site as specified in the U.S. EPA 2.12

Use the following procedure to equilibrate the 47 mm filters after
sampling.
1.
Separate the filter from the cassette with the optional filter cassette
separator tool (38-004892) as shown in
Figure 3–9
.
Figure 3–9.
Filter Cassette Separator Tool
2.
Remove the 47 mm filter from the filter cassette and set the filter in its
petri dish. The cassette can then be used to hold other filters once it has
been cleaned.
3.
Examine the filter for defects that may have occurred during sampling,
and for evidence of leaks in the filter cassette. To check for leaks in the
filter cassette, check the filter for pronounced radial streaks that extend
beyond the exposed area of the filter.
