Teledyne API Model T360/T360M Operation Manual

4.8.6. Range Units

Concentrations displayed in mg/m3 and ug/m3 use 0  C, 760 mmHg for Standard Temperature and
Pressure (STP). Consult your local regulations for the STP used by your agency.
Select the preferred
concentration unit.
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 T360 can display concentrations in parts per billion (10
6
parts per million (10
UG), milligrams per cubic meter (mg/m
sample gas, %). Changing units affects all of the display, analog outputs, COM
port and DAS values for all reporting ranges regardless of the analyzer's range
mode.
Conversion factors from volumetric to mass units are:
CO : ppb x 1.96 = µg/m3; ppm x 1.96 = mg/m3
