12. OPERATING MODES
The XD One has four user-selectable operating modes for use in varying environments and
reporting requirements.
•
Normal (default)
•
In-cab
•
Data log
•
Live data
12.1 Power management
'Normal' mode captures and records data at a specified logging interval, allowing the XD One
to provide real-time warnings and alarms on changing particulate levels.
'Normal' mode is intended for use when the XD One is used to monitor individual exposure to
particulate levels within a working environment.
When configured to 'Normal' mode and connected via USB interfaces, the XD One will power
down its particulate sensor to allow for faster charging and data download.
'Normal' mode is indicated through the flashing of the battery indication symbol during normal
operation.
The use of the XD One in 'Normal' mode allows for both real-time alerts and data capture to
take place simultaneously. Warning alarms can be set against a single PM value; however the
XD One will log sensor data for the following sizes for offline review.
•
PM1.0
•
PM2.5
•
PM4.25
•
PM10.0
The XD One also records the TSP measurement for all particulates that have passed through
the sensor during its operational period. This includes particulates between the size range of
0.35 µm and 40 µm.
During Normal operation mode, the XD One will record data for all PM values at the specified
log rate for download and offline analysis. When recording PM readings to the internal
memory, the XD One will log the maximum value for each size at the specified logging interval.
