Trolex XD One Operating Modes

Modified on Tue, 13 Feb at 11:42 AM

The XD One has four 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 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 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.

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 XD One ‘In-cab’ mode allows for the same operating functionally as ‘Normal’ mode but can also be continuously used in a vehicle when connected or powered via USB.

This mode is indicated via the solid illumination of the battery symbol during operation as highlighted below:

The XD One will turn itself off after five minutes after USB power has been removed to save power.

Data Log Mode

The XD One ‘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 two turquoise illuminated icons as highlighted below:

Live Data Mode

The ‘Live Data' mode allows the XD One 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 two violet illuminated icons as highlighted below:
