6.4.6. Setting the Measurement Range Unit Type

The M300E can display concentrations in ppb, ppm, ug/m
units affects all of the COM port values, and all of the display values for all
Measurement Ranges. To change the units of Measure press:
Select the preferred units of
measure.
EXAMPLE: Switching from
PPM to UGM
Concentrations displayed in mg/m
Temperature and Pressure (STP).
Consult your local regulations for the STP used by your agency.
Once the units of Measurement have been changed the unit 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.
The following equations give approximate conversions between volume/volume
units and weight/volume units:
