11.10 PM density
Allows the user to set a custom PM density value for known particulates in the installation
environment.
Note: The Air XD uses a PM density value to calculate the mass of known particulates in the
installation environment (1.65 g/ml as default).
11.11 Averaging settings
These averaging settings allow the user to set two separate averaging periods or time bases
for all PM channels, including TSP.
Users can select a range between 1 minute and 24 hours.
11.12 Alarm settings
The Air XD offers two user configurable alarms. Each alarm requires four parameters to be
selected and configured. All alarms are logged in the Air XD event log.
• Assigned a PM size/channel (PM1.0, PM2.5, PM4.25, PM10.0 and TSP)
Select one of the four configured PM sizes or TSP as the alarm source.
• Assigned a data source/channel
Select whether to act on live data readings or one of the pre-configured averages (15
minutes to 8 hours).
