between volume/volume units
and weight/volume units:

The T200 can display and report concentrations in ppb, ppm, ug/m
Changing units affects all of the COM port values, and all of the display values for all
reporting ranges. To change the units of measure press:

Concentrations displayed in mg/m3 and ug/m3 use 0C
Standard Temperature and Pressure (STP).
Consult your local
(Example: US EPA uses 25C as the reference temperature).
Once the Units of Measurement have been changed from volumetric (ppb or ppm)
to mass units (ug/m3 or mg/m3) the analyzer MUST be recalibrated, as the
―expected span values‖ previously in effect will no longer be valid.
Simply entering new expected span values without running the entire calibration
routine is not sufficient. This will also counteract any discrepancies between STP
definitions.
The dilution ratio feature is a software utility option designed for applications where the
sample gas is diluted before being analyzed by the T200. Typically this occurs in
continuous emission monitoring (CEM) applications where the quality of gas in a smoke
stack is being tested and the sampling method used to remove the gas from the stack
dilutes the gas. Once the degree of dilution is known, this feature allows the user to add
