NOTE
On analyzers with the multigas option activated (see Section s 4.5.1 and 6.8) the concentration value will
switch back and forth between from “H2S=XXX.X” to “SO2=XXX.X” depending on which gas is currently
being measured.
Also, The analyzer will switch between the HIGH and LOW analog reporting ranges
whenever the concentration level of the gas being currently measured fulfills the trigger
criteria listed at the beginning of this section.
4.4.4.7. Range Units
The T101 can display concentrations in parts per billion (10
9
mols per mol, PPB ), parts
per million (10
6
mols per mol, PPM ), micrograms per cubic meter (µg/m
3
, UG ) or
milligrams per cubic meter (mg/m
3
, MG ). 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.
