Document the relative humidity, temperature, date and time of the
initial weighing.
9.
The “zero” reading of the microbalance should be verified between each
filter weighing.
Collection filters must be transported carefully in the provided transport
containers to and from the sampling site, as specified in the U.S. EPA 2.12
Quality Assurance Handbook
, Section 8. As specified in the
Quality
Assurance Handbook
, the transport containers must be conductive or static
free. The transport container used for the Partisol 2000
i
is a metal
container, while the container provided for the Partisol 2000
i
-D is made of
anti-static plastic.
Use the following procedure to exchange each filter cassette:
1.
Determine from the Main Screen whether the unit is still sampling, i.e.,
whether it is in the Sampling Operating Mode (SAMPLE on the left
side of the Status Bar of the screen). The Main Screen displays the
current time/date, as well as the programmed starting and ending
time/date. If the device is still in its Sampling Operating Mode, allow it
to complete its current sampling program before executing the steps
below. Refer to Chapter 9 “
Firmware Screen Descriptions
”.
2.
If the device is in the Stop or Error Operating Mode, press the
key on the keypad to return the Sampler to the Stop Operating Mode.
This causes the Sampler to write the final information to the current
record of filter data, and must take place before removing a currently-
installed filter.
