  • What does XD1+ internal memory electronics failure mean?

    This fault means XD1+ has detected an electronic failure of the internal memory.

    The device alerts the user and enters an error state. Contact Trolex or an approved distributor.

  • What does XD1+ particulate sensor electronic failure mean?

    This fault means XD1+ has detected an electronic hardware failure of the particulate sensor.

    The device alerts the user and enters an error state. Contact Trolex or an approved distributor.

  • What does XD1+ device settings corrupt mean?

    This fault means corruption was detected in the XD1+ settings.

    The device automatically reverts to factory defaults and continues operation, so custom configuration should be checked and reapplied in BreatheLITE as needed.

  • What does XD1+ particulate sensor data error mean?

    A particulate sensor data error means data received from the particulate sensor was corrupt. XD1+ ignores the reading, logs the event, and continues operation.

    If this occurs more than four times, XD1+ alerts the user and enters an error state. Contact Trolex or an approved distributor.

  • What should I do if XD1+ internal memory is full?

    If XD1+ internal memory is full, download and clear XD1+ data, event logs, and alarm logs.

    Confirm that required records have been downloaded before clearing stored data.

  • What does XD1+ internal memory corruption mean?

    Internal memory corruption means data loss has occurred or readings cannot be recovered.

    The manual states that XD1+ will automatically format its memory and continue operation.

  • What should I do if XD1+ reports a non-recoverable fatal error?

    For a non-recoverable fatal error, XD1+ stops normal operation and alerts the user with flashing red LEDs and an audible sequence.

    The manual recommends contacting the Trolex service team for support.

  • What should I do if XD1+ reports a recoverable error?

    In a recoverable operating error, XD1+ logs the event and automatically takes action to resolve it.

    After notification of recovery, check previous data capture and device settings before continuing. User settings may need to be redefined in BreatheLITE.

  • How do I update XD1+ firmware?

    When Trolex releases updated operating firmware and instructions, connect XD1+ to BreatheLITE to perform the local update.

    Trolex provides notification, release notes, and update instructions for the latest firmware.

  • How do I download XD1+ data?

    Connect XD1+ to the BreatheLITE application. The device is designed to collect particulate data during operation for download, review, and analysis through the BreatheLITE data analysis tools.

    The multiway data and charging dock can connect up to five XD1+ devices for charging and data collection.

  • How do I configure XD1+ in BreatheLITE?

    Connect XD1+ to BreatheLITE. The software allows configuration of device name, COM port, operating mode, alarm PM size, TWA period and threshold, STEL period and threshold, log rate, and particle density.

    Use the BreatheLITE in-application help for detailed configuration steps.

  • How do I acknowledge an XD1+ alarm?

    Press, hold, and release the power button after two seconds. XD1+ confirms acknowledgement with an LED sequence.

    Acknowledgement silences the audio alarm, but the LED remains solid while the alarm condition is still present. The alarm resets only when particulate levels fall below 95% of the alarm setpoint.

  • How do XD1+ STEL and TWA alarms behave?

    XD1+ uses two LED icons and audio sequences. The STEL alarm flashes the amber icon with two beeps per second. The TWA alarm flashes the red icon with three beeps per second.

    If both alarms trigger at the same time, the TWA alarm takes priority.

  • What is XD1+ In-cab mode used for?

    In-cab mode keeps the particulate sensor and device warnings active while XD1+ is connected or powered via USB, allowing continuous use in a vehicle.

    The device turns itself off five minutes after USB power is removed to save power.

  • What is XD1+ Data-log mode used for?

    Data-log mode follows Normal mode data capture behaviour, but readings are not checked against alarm thresholds and on-device warnings do not trigger.

    It is intended for passive monitoring where data is downloaded and analysed later in BreatheLITE.

  • What operating modes does XD1+ provide?

    XD1+ has four selectable operating modes: Normal, In-cab, Data-log, and Live readout.

    Normal mode captures data and checks alarms; In-cab keeps sensing and warnings active while powered via USB; Data-log records without warning alarms; Live readout streams live particulate data to BreatheLITE via USB.

  • How is XD1+ battery calibration restored?

    The battery health is continuously monitored during operation and is calibrated when the battery is fully charged.

    If the battery is fully depleted, XD1+ loses the current stored battery calibration data. Fully charging the device recalibrates battery monitoring.

  • What happens if XD1+ battery reaches 0%?

    XD1+ initiates automatic low-power shutdown and runs the power-off sequence. If the user attempts to power the device on without enough charge, it immediately runs the shutdown sequence again.

    Fully charge the device before restarting monitoring.

  • What are the XD1+ battery indications?

    A green flashing battery icon indicates 100% to 70% charge. Amber indicates 69% to 40%. Red indicates 39% to 10%.

    Below 10%, the red warning flashes every second. At 0%, XD1+ initiates automatic low-power shutdown.

  • What happens if XD1+ self-test fails?

    If the self-test returns a fail result, XD1+ checks whether the fault is recoverable and repeats the self-test up to four times.

    If the fault becomes a fatal error indication, the manual recommends contacting the Trolex service team.

  • How do I run a manual XD1+ self-test?

    During normal operation, press and hold the power/function button until all three function icons are blue, then release the button.

    XD1+ runs the self-test sequence and displays the pass or fail result through the audible and visual indication sequence.

  • What does the XD1+ self-test check?

    The XD1+ startup self-test checks OPC sensor communications, internal electronic hardware, battery function and calibration, data logging communications, and EEPROM memory so custom user settings are not lost.

    A pass is shown with green flashing icons. A fail is shown with red flashing icons.

  • How do I power down XD1+?

    Press and hold the function button to initiate the power-off sequence, then release the button when all icons illuminate white.

    The icons illuminate incrementally before the device powers down.

  • When does XD1+ begin sampling?

    XD1+ begins particulate sampling as soon as the power-on and startup routine is complete.

    STEL and TWA calculations, alarm warnings, and data recording become active alongside particulate sampling following the power-on sequence.

  • How do I power on XD1+?

    Before first power on, fully charge XD1+ using the supplied charger. Press and hold the function button, then release it when all icons illuminate white.

    The device runs a startup routine, performs self-test, displays a pass or fail result, and then automatically begins particulate sampling.

  • What are the XD1+ default settings?

    XD1+ defaults include operating mode Normal, alarm PM size PM4.25, TWA period 8 hours, TWA threshold 1000 µg/m3, STEL period 15 minutes, STEL threshold 1000 µg/m3, log rate 10 seconds, and particle density 1.65 g/ml.

    Default settings can be changed using Trolex BreatheLITE and BreatheMOBILE.

  • What particle sizes does XD1+ monitor?

    XD1+ supports PM1.0, PM2.5, PM4.25, and PM10 measurement ranges, with a particle sizing range of 0.1 µm to 10 µm.

    The device alarms against a selected PM value but logs multiple PM sizes for offline review.

  • What does the XD1+ Personal Dust Monitor do?

    XD1+ is a personal wearable dust monitor designed to provide real-time data on airborne particulate levels and warn users about harmful personal exposure in working environments.

    It displays measurement information through custom STEL and TWA audio-visual alarms and supports data analysis with BreatheLITE and BreatheMOBILE software.

  • What maintenance interval is suggested for low or medium dust loading?

    For AIR XD, XD1+, and XD ONE, low dust loading up to 5 mg/m3 is associated with a 6 to 12 month maintenance schedule. Medium dust loading up to 10 mg/m3 is associated with a 3 to 6 month schedule.

    These intervals are guidance and should be reviewed against actual site conditions.

  • What maintenance interval is suggested for high dust loading?

    For AIR XD, XD1+, and XD ONE, high dust loading is described as 10 mg/m3 or above, with an expected maintenance schedule of 1 to 3 months.

    The manuals state that particulate type and operating environment vary, so this should be used as a guide rather than a fixed rule for every site.

  • Why is maintenance frequency based on dust loading?

    The manuals note that particulate types and operating environments vary. AIR XD, XD1+, and XD ONE provide maintenance guidance based on average dust loading: low loading up to 5 mg/m3, medium loading up to 10 mg/m3, and high loading at 10 mg/m3 or above.

    The schedules are guidance only; the site environment should be assessed periodically to set the appropriate routine.

  • What should I check if readings seem unexpectedly low?

    Confirm the inlet or top cap is open where applicable, check that entry and exit apertures are not blocked, verify the selected operating mode, check the configured PM channel or RCS averaging period, and confirm that the device has completed its startup or self-test routine.

    For fixed instruments, also check power and communications. For portable devices, check battery level and whether the sensor is active in the selected mode.

  • What should I check if readings seem unexpectedly high?

    Check for local dust events, atomised spray or mist, the device position relative to the source, blocked or contaminated flow paths, recent maintenance status, particle type, airflow patterns, and whether the configured PM size, density, averaging period, or alarm channel matches the intended application.

    If the reading is accompanied by a fault, follow the fault-code guidance for the product.

  • Can real-time particulate monitors be used as the only compliance method?

    The AIR XS manual is explicit that real-time monitoring is indicative and is not currently suitable for compliance monitoring or regulatory compliance for RCS. Other particulate manuals frame the devices as warning, monitoring, logging, and analysis tools that must be used within their stated limits.

    Always align alarm thresholds, interpretation, and reporting with local legislation, site rules, and the applicable manual.

  • What environmental limits should be considered before using a Trolex particulate monitor?

    Each monitor must be operated within the temperature, humidity, ingress protection, and use limits in its technical section. The manuals warn that operating outside those limits may damage equipment or prevent the product achieving its performance specification.

    Operation at temperature extremes for extended periods can reduce product operating lifetime.

  • Why should particulate inlets and outlets stay clear?

    The monitors rely on an unobstructed particle flow path. If the inlet, top cap, outlet, grille, or exit aperture is blocked, particulate sensing airflow can be reduced or prevented.

    Blocked airflow can lead to unexpected readings, fault conditions, failed checks, or loss of monitoring function depending on product and severity.

  • What does a fail result mean after a compliance check?

    A fail result means the device did not meet the response threshold used by the compliance check. The manuals instruct users to clean the sensor or dust path, repeat the check, and note the result.

    If the device repeatedly fails, contact Trolex or an approved service route for support.

  • What does a pass result mean after a compliance check?

    A pass result means the particulate sensor is functioning as expected against the compliance check routine and normal monitoring operation can resume.

    The result should still be considered part of the product maintenance record rather than a replacement for any required site procedure.

  • How should the dust path be cleaned?

    For AIR XD, XD1+, XD ONE, and AIR XS, the manuals describe wiping inlet surfaces with a damp cloth and using canned compressed clean air for 10 to 15 seconds to clear the dust path.

    Follow the exact product procedure and only carry out maintenance within the limits allowed for the device.

  • How should particulate monitor labels and displays be cleaned?

    The manuals recommend periodic cleaning with a damp cloth so that displays, keypads, membranes, rating labels, and product labels remain clean and legible.

    Do not use this as a substitute for the product-specific sensor or dust-path cleaning procedure where one is required.

  • What routine visual checks apply to particulate monitors?

    Routine visual checks should look for external damage, cracked or broken plastic parts, damage to wiring or USB cables where applicable, damaged membranes or buttons, blocked particulate entry or exit apertures, damaged mounting hardware, and missing, peeling, or discoloured labels.

    The exact checklist varies by product, but the maintenance sections consistently link these checks to IP rating, airflow, legibility, and safe operation.

  • How often should portable XD devices have a compliance check?

    The XD1+ and XD ONE manuals describe 3-monthly compliance checks using the Trolex Compliance Pack+ and BreatheLITE automated test routine.

    The check uses reference material dosed into the particulate dispersion hood while the device is positioned in the compliance base.

  • What should I do if a compliance audit check fails?

    Run the sensor cleaning procedure described for the product, then repeat the compliance audit check and record the result. If the repeated test passes, normal monitoring can resume.

    If the device returns a repeated fail result, the manuals instruct users to contact Trolex or an approved support/service route to discuss servicing options.

  • What is a compliance audit check?

    A compliance audit check is an instrument function used to check device response against reference particulate material. The manuals describe use of a particulate dispersion hood or compliance base, reference particle sizes, and a dosing bottle.

    A pass result indicates that the particulate sensor is functioning as expected. A fail result should be followed by the cleaning and repeat-test steps in the relevant manual.

  • Why is particle density configurable?

    Particle density is used when the instrument converts measured particulate information into a mass concentration value. AIR XD, XD1+, and XD ONE include a default particle density of 1.65 g/ml and allow the value to be configured for known particulates in the installation or operating environment.

    Use the product configuration method described in the relevant manual when a site-specific density value is required.

  • Can atomised dust suppression or mist affect readings?

    Yes. The AIR XD, XD1+, and XD ONE manuals state that readings will include atomised or misted sizes that pass through the sensor within the particle detection range.

    When locating or operating a monitor near atomising dust suppression systems or moist spray, consider that the instrument may count those particles as part of the measured particulate environment.

  • How does airflow affect particulate measurements?

    Particulate readings depend on particles passing through the sensing flow path. The manuals warn that blocked inlets, blocked exits, clogged grilles, or obstructed apertures can obscure the sensing airflow and affect device function.

    Install, wear, or mount the product so that the entry and exit apertures remain clear, and include aperture checks in routine maintenance.

  • Why are real-time mass concentration readings treated as indicative?

    Real-time optical particulate instruments infer mass concentration from particle measurements and assumptions about the sampled material. The AIR XS manual states that mass concentration data from optical sensors should be treated as an indicator and may vary with particle type, test condition, and local environment.

    The value is useful for showing changes in airborne particulate levels over time, but it should not be treated as a direct substitute for every regulatory or laboratory method unless the relevant manual and local compliance process allow it.

  • Why can two particulate monitors near each other show different readings?

    The manuals note that the position of a device relative to the target sample can affect the observed measurement. Particle saturation, local airflow, dust type, device configuration, drift over time, maintenance condition, and heavy dust exposure can all contribute to differences between nearby devices.

    For this reason, readings should be interpreted with awareness of the local environment and the way the instrument is installed or worn.

  • What does TSP mean?

    TSP means Total Suspended Particulates. Where supported, the instrument can report a wider suspended particulate reading in addition to selected PM size channels.

    AIR XD and XD ONE explicitly include TSP reporting. XD1+ logs PM1.0, PM2.5, PM4.25 and PM10.0 for review, while AIR XS is focused on respirable crystalline silica rather than TSP.

  • What does particulate matter (PM) mean in Trolex particulate monitors?

    Particulate matter, or PM, is the general term used for solids and liquid droplets suspended in air. The manuals describe PM as material that may come from combustion, industrial activity, natural sources, or working processes.

    Trolex particulate monitors report selected PM size fractions so changes in airborne particulate levels can be viewed, logged, alarmed, or analysed depending on the product.

    • Place XD1+ over RASOR until the tag is read.
    • Place operator ID card over RASOR to assign XD1+ to worker.

  • Will water mist and airborne droplets effect the readings on my AIR X unit?

    Typically, water droplets (such as rain) won’t register on the unit as they are too large, and the unit is designed to prevent ingress.

    Fine mists may be detected by the sensor as they will be able to pass through if they don’t have the mass to fall vertically, consideration should always be given to this when interpreting your data and occasionally dense mist may cause saturation of the device readings.

  • How many compliance checks do I get out of a single vial of reference dust for my AIR X Dust Monitor?

    You should get approximately 5 compliance checks to 5 different units out of 1 vial of reference dust. We recommend this because the longer you keep the reference dust in the asperator (or spray bottle), the higher the chance that moisture will get in and cause the dust to merge, which will cause your device to not monitor for the correct size dusts.

  • How often should I carry out a compliance check to my AIR X Dust Monitor?

    We recommend that a compliance check is carried out every 3 months. However, in activities where your unit is exposed to extremely high levels of dust, this should be done more frequently to ensure your device is working as required.

  • What happens to AIR X unit during a compliance check?

    The sensor is expecting a range of dust particles between 0.3 and 40ug during this test, when the dust sample is applied the laser will size the dust particles and organise them in to the correct bins and then analyse the data, if all bins are filled this confirms the laser is working across the complete range and the unit will confirm this with a ‘PASS’ indication.

    In the event that your device fails its compliance check, we recommend you that you run a sensor cleaning operation as highlighted in ‘Compliance check’ section of the user manual.

  • What do I get in my Compliance Pack+?

    You’ll get enough reference dust to carry out a compliance test for an entire year. You’ll get

    • 1 x base station that the device sits in
    • 1 x hood with a hole for the dust particles to be sprayed through
    • 4 x vials of reference dust which contains different sized particles
    • 4 x asperators (or spray bottles)

  • Where can I download BreatheMOBILE?

    You can download BreatheMOBILE here or from the Apple or Google Play stores.

  • Where can I download BreatheLITE?

    You can download BreatheLITE here.

  • What’s the best practice for maintaining my XD1+ Personal Dust Monitor?

    We recommend regularly carrying out the following actions in the order they appear:

    1. Check for external damage to the device. Plastic parts should not be cracked or broken which could affect
    2. the IP rating of the product.
    3. Check for damage or wear to the main product membrane, LED icons and power/function switch.
    4. Check for damage to the USB data / charge port.
    5. Remove the silicon cover and regularly cleaning with a damp warm cloth to prevent stray dust particles.
    6. Wipe the unit down with a damp cloth at the end of the day after use.
    7. Use a small paint brush clean the any external dust or debris caught within the grille.
    8. Use canned compressed clean air, spray the device inlet for 10 to 15 seconds to clean the dust path.
    9. Wipe down the XD1+ inlet surfaces with a damp cloth to remove any external dust and debris.

  • Why do I need to carry out a compliance check to AIR X Dust Monitor(s)?

    Carrying out a compliance check to your device tests that your it’s monitoring for the correct size dust particles. This means that when your device is in use, you know that it’s monitoring for all
    particulates ranging from PM1 to PM10.

  • What’s the lifespan of the XD1+ Personal Dust Monitor?

    As long as the monitor continues to pass its compliance check, and the structure of the monitor is as manufactured (i.e. no damage to the housing etc.) the unit can continue to be used.

  • Why does the Compliance Pack+ have 4 bottles of dust when It’s for a year’s use? I’ve done my compliance test and there’s plenty of dust left for the next compliance test.

    As the test dust is used to check the performance of the monitor, there has to be very tight tolerances in the process, as you’ll see on the dust vial, the dust has a wide spread of particle sizes from 0.36 μm to 40 μm, once the vials have been opened, moisture can cause the particles to amalgamate, which would lead to the monitor failing a compliance check, as the particles won’t be of the correct size spread.

  • Can I use a single Compliance Pack+ for more than 1 XD1+ device?

    This depends on the frequency and concentration of the dust when the compliance checks are done. In internal lab testing we have compliance checked 3 monitors on one bottle of compliance dust.

  • Why do I need to carry out dust and silica monitoring?

    Regulation 10 of the Control of Substances Hazardous to Health Regulations (COSHH Regulations) speaks to the duty placed on employers pertaining to “Monitoring exposure at the workplace”.

    With particulates it’s not always immediately obvious whether there is a risk to the health of employees. More often than not, dangerous levels of exposure to particulate matter are regularly invisible to the human eye.

    Furthermore, monitoring will provide a better understanding of when, where and why exposure is occurring.

    Failure or deterioration of the control measures could result in a serious health effect, so regular or continuous monitoring is critical to ensure no changes have occurred to mitigate the controls. Direct reading monitoring technology is also the best possible short-term measure to evaluate the effectiveness of control measures.

    Demonstrating duty of care to your employees and visitors by investing in monitoring is a positive way to influence Health and Safety culture.

  • Why does my AIR X unit have different TWA time frames?

    Most of our devices have 1,2,4,8 and 12-hour time-weighted avarages (TWA) this is because a TWA inherently will take into account any (or zero) readings into its average.

    Where the device or consideration for a persons’ exposed hasn’t been operating for the 8-hour average, the calculation will include the null period of zero readings. Reducing the on device reading can be misleading if it’s not understood, so shorter time frames are included for local extrapolation depending on requirement.

    Note: If you’re looking for indicative readings against an 8-hour sample then the 8-hour average reading should be used, but the device must be running for 8 hours before the reading is
    generated.

  • Will the use of atomised particulate suppression and mist sprays affect device readings?

    It’s recommended that real-time monitors are operated with location and proximity consideration to any atomising dust suppression systems. Device readings will include counts based on atomised or misted sizes that pass through, within the particle detection range of the sensor.

  • What do I get in my AIR X Compliance Pack?

    • 1 x base station that the device sits in
    • 1 x hood with a hole for the dust particles to be sprayed through
    • 4 x vials of reference dust which contains different sized particles (enough reference dust to carry out a compliance test for an entire year)
    • 4 x asperators (or spray bottles)
