4.8. SETUP  RNGE: RANGE UNITS AND DILUTION

CONFIGURATION

This Menu is used to set the units of measure to be associated with the analyzer’s

reporting ranges (see Section 4.13.4.2. for more information on reporting ranges vs.

physical ranges) and for instruments with the sample gas dilution option operating, to set

the dilution ratio.

4.8.1. RANGE UNITS

The T200H/M can display concentrations in parts per million (106 mols per mol, PPM)

or milligrams per cubic meter (mg/m3, MGM). Changing units affects all of the

display, COM port and DAS values for all reporting ranges regardless of the analyzer’s

range mode. To change the concentration units:

Conversion factors from volumetric to mass units used in the T200H/M:

NO: ppm x 1.34 = mg/m3

NO2: ppm x 2.05 = mg/m3

Concentrations displayed in mg/m3 and µg/m3 use 0° C and 760 Torr as standard

temperature and pressure (STP). Consult your local regulations for the STP used by

your agency. EPA protocol applications, for example, use 25° C as the reference

temperature. Changing the units may cause a bias in the measurements if standard

temperature and pressure other than 0C and 760 Torr are used. This problem can be

avoided by recalibrating the analyzer after any change from a volumetric to a mass unit

or vice versa.

Note In order to avoid a reference temperature bias, the analyzer must be

recalibrated after every change in reporting units.
