Please bear in mind, that there is a non-linear relationship between g/Nm
3
and
ppm
v
on one side and %wt/wt resp. %wt(air) on the other side. Also, the full range
concentrations are not exactly the same upon switching, as the range limits are
rounded values.
Note: Accordingly, the analog outputs may change, when the ozone concentration
unit is changed.
Furthermore, the thresholds of High & Low Alarm are recalculated automatically.
For a complete list of available ranges, please refer to the latest order sheet.
Pressure
The unit of absolute pressure shown on the display can be changed from bar to psi,
Torr or MPa. Here are some examples for recalculation of pressure range when
changing the unit:
bar
psi
