4.3.2 Setting Units
All data in the Monitor is stored as raw data. The different units,
which you can select here, enable you to enter gas concentrations
and to display temperatures, lengths and pressures in units, which
you are comfortable with. These units are also used to present
measurement data in a form that is most convenient for you.
The Monitor can display gas concentrations either in absolute units of
mg/m3 unit that is dependent on a particular temperature, termed
the normalization temperature, or in units of parts per million (by
volume) – which is independent of the temperature of the gas. You
can inform the monitor about the units you intend to use – for
example: the length of the sampling tube attached to the Monitor’s
inlet (in meters or feet) atmospheric pressure (kPa or mBar or
mmHg) and unit for humidity (ppm or Tdew or kPa or mg/m 3 ).
The measurement units can be changed using the push-buttons on
the front of the monitor:
1. Press SET-UP.
2. Press S3 and then S2.
The following text appears on the screen display:
