The Gas Units screen defines how the SO
2
concentration readings are
expressed. Gas units of parts per billion (ppb), or micrograms per cubic
meter (
μ g/m
3
) are available. The μ g/m
3
gas concentration is calculated
using a standard pressure of 760 mmHg and a standard temperature of 20
°
C.
When switching the selected units from ppb or
μ
g/m
3
, the analog ranges all
default to the highest range in that mode. For example, when switching
from
μ
g/m
3
to ppb, all the ranges default to 1000 ppb.
Therefore, whenever you change units, you should also check the range
settings.
In the Main Menu, choose Range > Gas Units .
Note If the units change from ppb to
μ
g/m 3 or vice versa, the instrument
should be re-calibrated, particularly if the user’s standard temperature is
different from 20 °C. A display warning will appear that ranges will be
defaulted and calibration parameters reset.
