Frequently Asked Questions: dBadge2 Personal Noise Dosimeter
What are the biggest differences from the current dBadge?
The biggest differences are dBadge2 has:-
- a full colour display
- the addition of Bluetooth® 4.0 low energy wireless connectivity with supporting Airwave App.
- a much larger memory that allows a 1 second time history profile
- a pause function and motion sensor.
- dBadge2 downloads using USB via a Docking Station (that also serves as a charger) rather than an IR port as on the original dBadge.
- audio event and notes recording and real-time octave band analysis are also available as options
Is there an intrinsically safe (IS) version?
Casella has the experience of several generations of IS dosimeter products dating back to the 1970’s. dBadge2 is no exception and has been designed to be capable of meeting the very latest 2014 revisions of the globally recognised IEC 60079 series standard. Certification is expected within 6 months of launch.
What are the Plus and Pro models?
These variants add optional features. The Plus model adds audio event and notes recording capture whilst the Pro model adds in real-time octave band analysis (as well as audio event capture). These are useful for source identification and for undertaking control measures.
Does dBadge2 still calculate all parameters for later analysis like the original dBadge?
Yes, the user doesn’t have to worry about set ups because all permutations and combinations of parameters are available for later analysis if required. The user simply chooses what to display on the screen with up to three simultaneous dosimeter set ups, D1, D2 and D3. It is a fool proof measurement strategy in this regard.
What are D1, D2, D3?
These are dosimeter setups that simply determine what is displayed on the dBadge2 colour screen. There are 6 pre-defined Internationally recognised settings to choose from with combinations of threshold (T), criterion (C) and exchange rate (Q) as well as a custom setting that allows a ‘mix and match’ of T, C and Q. This is useful for organisations who want to go beyond minimum compliance by applying more stringent criteria.
How do I get a custom set up?
This is configurable using the dBadge2 plug-in for Casella Insight data management software
Can I use just one dosimeter setting?
Yes, D1 is always active whilst D2 and/or D3 can be disabled using the configuration menu. Using additional D2 & D3 is primarily for US users who may want to simultaneously compare, for example, OSHA HC, OSHA PEL and ACGIH on the display or Airwave App.
How do I review or change the dBadge2’s general settings?
You can do this in one of two ways either directly on the instrument by cycling through the configuration menu available when you switch the dBadge2 on or by using the Insight software plug-in. To enter the configuration menu, simply press the right hand button immediately on power-up. Cycle through the menu options and make changes using the left and right hand keys as prompted by the display.
What does run mode mean?
Run mode means that the instrument is calculating and gathering data and storing it to memory. Run mode can be initiated manually on the instrument by pressing and holding the left and right hand keys simultaneously for 3 seconds, via simple on/off timers (accessible form the Configuration Menu) or using the remote start/stop/pause commands on the Airwave app.
Is there a pause function?
Yes, although only a few measurement regimes require this functionality and it can be enabled/disabled in the configuration menu.
What is the motion sensor for?
Given the unattended nature of the noise dose measurements, there is an element of trust that the worker will buy into the need for monitoring and not take the dBadge2 off! The motion sensor evidences the amount of motion/movement that was detected during the measurement run and presents it as a 'track' in Casella Insight along with profile data etc. You can then make a decision on the validity of the sample and have more confidence in your data.
What is the battery life and charge time?
Battery life is in circa 35 hours and a full charge can be achieved in 6 hours. However, a shorter charge time can be made to give the minimum run-time required since dBadge2 can be charged at any time. The resulting available run time may be checked on the dBadge2’s screen whilst in the Docking Station. If the screen is blank simply tilt the docking station or press the left hand key to wake the dBadge2 up.
How do I know what condition the batteries are in?
Batteries don’t last forever and this will depend upon usage and the number of battery cycles. The dBadge 2 has a battery diagnostic mode that fully cycles the batteries to establish their storage capacity and performance.
What is the benefit of wireless?
Bluetooth® 4.0 low energy wireless connectivity and the dedicated Airwave app means that users can remotely start, stop or pause a run, check instrument status, current measurements and battery life all in (near) real-time. This means that they will minimise the disturbance of workers performing their daily tasks and it will also maximise the productivity of the busy H&S professional by ensuring that results are captured with confidence.
Where do I ‘find’ the Airwave App and USB download utility?
These can be found in the Support section of the Casella website under the dedicated Product Support pages for dBadge2
Can the app detect more than one instrument?
Yes, in theory this could be many hundreds including a mix of Casella wireless enabled products that will be launched in the near future.
Can I set up the dBadge2 from my phone app?
At launch no, but further functionality is planned.
What is the wireless range?
dBadge2 uses Bluetooth® 4.0 low energy wireless, which means a range of circa 25 metres line-of-sight but exact range will depend upon the local ‘built environment’ e.g. structures, process plant, local radio fields.
Can I disable the Bluetooth?
Yes, either using the configuration menu or permanently using the utility supplied that allows the wireless connectivity to be deactivated. Wireless options will then not appear in the configuration menu.
I can’t use a phone, how can I best use the display?
Casella has used the colour display to its full advantage by operating a ‘traffic light’ system such that a green, amber or red value will signify exceedance with a pre-set limit. You can also choose to show results using a large font whilst in run and stop modes. D1, D2 and D3 are also colour differentiated in the display header.
What is the flashing LED for?
The LED has two functions. It flashes red when charging and blue when fully charged. When in a measurement run, it also flashes red to indicate that the dBadge is running (when the display blanks) and blue at a slow rate when a lower level exceedance is active and at a fast rate whenever an upper level alarm has been triggered.
How do I download data?
dBadge2 now downloads through connections in the docking station that also acts as a three-way charger. The left-hand ‘pocket’ is configured for connection to the PC via USB, which makes it easy to track which instrument is being downloaded and as with other current Casella products you can download to Insight software using the dedicated plug-in. There is also a download utility which presents data in an XLS format ready for importing into a spreadsheet. If you are using the Airwave app you can email the summary data, with your own notes and photographs in the normal way.
