Lasair II Particle Counter Operations Manual
Page 8-5
FS-209E Standard
The document, FED-STD-209E (11 September 1992), was used when designing
the FS-209 module, and only the classes specified in the document’s tables have
been implemented.
If the number of locations is less than five, the number of samples required at each
location is increased to a minimum of five samples. This may result in six or more
samples being taken so that the Lasair II particle counter will accept the result.
