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
The following information details each mode and supporting functionality during operation.
Normal mode captures and records data at the 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 device is used to monitor individual personal
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.
This operating 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 alerting and on-device data capture to
take place simultaneously. The XD One is designed to allow warning alarms to be set against a single
Particulate Measurement (PM) value, however the device itself 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 Total Suspended Particulate (TSP) measurement for all particulates that
have passed through the sensor during its operational period. This includes particulates between the
size range of 0.35um and 40um.
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.
In Normal mode, the user selected Alarm PM Size readings are taken every second and used to update
the applicable STEL and TWA calculations which are then checked against the configured alarm
thresholds.
