The XD1+ has 4 user-selectable operating modes for use in varying environments and reporting requirements:
1. Normal (default)
2. In-cab
3. Data log
4. Live data
Normal Mode
‘Normal’ mode captures and records data at the specified logging interval, allowing the XD1+ to provide real-time warnings and alarms on changing particulate levels
‘Normal’ mode is intended for use when the XD1+ 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 XD1+ 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 XD1+ in ‘Normal’ mode allows for both real-time alerting and on-device data capture to take place simultaneously. The XD1+ 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
When recording PM readings to the internal memory, the XD1+ 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.
In-cab Mode
The XD1+ ‘In Cab’ mode allows for the same operating functionally as ‘Normal’ mode, however, it allows the particulate sensor and device warnings to remain active when connected or powered via USB interfaces which allows the device to be continuously used in a vehicle.
This mode is indicated via the solid illumination of the battery symbol during operation as highlighted:
The XD1+ will turn itself off after 5 minutes after USB power has been removed to save power.
Data Log Mode
The XD1+ ‘Data log’ mode follows the operational functionality of ‘Normal’ mode, but readings are not checked against alarm threshold levels and on-device warnings / alarms will not trigger.
This mode is intended for use during passive monitoring of environments where data is captured for download and post-analysis using the BreatheLITE software.
This mode is indicated via 2 turquoise illuminated icons:
Live Data Mode
The ‘Live Data' mode allows the XD1+ to stream live particulate data to the BreatheLITE software via USB connection.
Particulate data is also logged to the internal memory for download and analysis as required.
This mode is indicated by 2 violet illuminated icons as highlighted:
