3 Configuration and operation
3.1 Parameters
The parameters described below are normally set using INFRA Net
Manager (Remote control), but can also be set using the display and
push-buttons of the Datalogger.
3.1.1 Standards
X20DM2 has two selectable standards, S01 and S02.
S01: The inlet air is heated. This standard is intended to be selected
when air humidity is above 50 %RH.
Note! This standard needs external power, because the battery of
Osiris is too weak to power the heating elements. If external power is
lost in this standard, the interval data will be tagged with
“Overload”.
S02: The inlet air is without heating. The instrument can be run
without external power for at least eight hours when Osiris internal
battery is fully charged.
Common for the two standards is that they deliver the four measured
channels:
Channel 1. PM10 Concentration.
Channel 2. PM2.5 Concentration.
Channel 3. PM1 Concentration.
Channel 4. TSP Concentration (Total Suspended Particle).
Each of these channels is the average value measured over the
selected Interval time. The unit of each channel is µg/m
