No, the i3 does not use a cradle like the i2. The improved i3 design lets you just use a USB cable to connect the dosimeter to the computer.

The dosimeter always measures and stores dose data on its internal memory, regardless of whether there is a display in range or not. You can view the dose history at any time by connecting the dosimeter to a computer running Dose Viewer.

To see the dose rate live, the dosimeter needs to be visible on a real-time display. The dosimeter shows up on any Real-time Display within communication range, it is not paired with a certain display.

The region inside the dashed red line is the active sensor area.

Note: Keep the active sensor area and its surroundings clean and free from stickers. Added material in the X-ray field may affect the measurement result.

No. The DXR+ has to be irradiated from the printed X-ray arrow and with a continuous field to give a correct result.

The VT305 is optimized for battery use. Ensure that the battery is fullycharged. The VT305 will operate on battery power for up to four hours ofcontinuous use. Shorter battery life will be experienced when the VT305 iscommunicating with computer applications such as the browser-viewedconfigurator, etc.

On the base unit side, use the Bluetooth device with USB connection that is provided by RaySafe (Laird BT820, pn: 1922064).

On the computer side there are various reasons for unstable Bluetooth connection such as incompatible hardware/software or environmental radio disturbances during measurements. Try turning off any programs on the computer that may interfere with the Bluetooth connection.

If the problem persists, you can try using a RaySafe Bluetooth USB device on the computer side as well. Turn off the internal Bluetooth.

Dose Manager is a software installed on your PC to see the history of dose exposures. You can see a dosimeter’s exposure over time and compare it to other dosimeters. With Dose Manager, you can also collect dosimeters exposure history from the Real-time Display and do not need to connect them individually to your computer. Dose Viewer compared to DoseManager can only show information for one dosimeter at the same time, and the dosimeter must be connected directly to your computer when you look at the history.

1. No, i3 badges are not legal dose of record. The readings they record should be used for reference and behavior modification.

Remove the luminance tube and ensure that the white illuminance window is clean. You can clean it with a damp cloth. If the problem persists, fill in a Service Request and send the detector for service.
I have connected the mAs cable but don't get any readings. What can I do?

The fastest way to charge the base unit is to use the supplied charger. You can also charge with USB cable connected to a computer or a USB charger, but this will take longer.

The i3 has improved wear-ability with a replaceable reinforced plastic clip. The i2 had a metallic clip that could not be replaced.

No, the dosimeter is designed for maintenance-free usage throughout its lifetime.

1. When the instrument is in measurement mode, press SELECT (long press) until "Waiting... Aborting measurement" is shown.
2. In the SETUP MENU, step (short press) to "Dose unit" and press SELECT until units are shown. Step to the desired unit and press SELECT until SETUP MENU is shown. The unit is now changed.

Note: If only Gray (Gy) is available, your instrument has been configured to comply with German regulations where the unit Röntgen (R) is not allowed.

The VT305 can be connected to mains power using the universal poweradapter and the appropriate prong-set (matched to the mains powerreceptacle). The power adapter connects to the VT305 via the USB cable.Alternatively, if a computer is being used during testing or documentation,you can connect the VT305 directly to the computer via the USB cable. Bothpower and data exchange are provided.

Panoramic dental machines can be challenging to measure on, primarily since the X-ray beam is narrow. Therefore, the positioning of the active sensor area is crucial.

Use DENT or R/F sensor.

Position the sensor in the exact center of the X-ray field, where you have the highest dose.

The positioning can be sensitive down to 0.1 mm. Use the RaySafe X2 panoramic holder to slide the sensor horizontally with high precision. Each mark on the scale represents 0.2 mm.

For details on how to use the panoramic holder, see the instruction video in our video library.

Dose Manager can be used with the new i3 dosimeters if you collect the dose information from your Real-time Displays using a network connection or with a USB memory. The i3 dosimeters unfortunately cannot currently be connected directly to Dose Manager by the USB cable.

1. No, the feedback is visual. Because of this, it is best for the Raysafe Display to be located in an easily visible location for the staff.

Check that the cable is properly connected. Try another cable.

Swipe right from the home screen to access the setup. System language is found under X2 Base Unit. You will be asked to restart the base unit for the setting to take effect.

The i3 has room for naming, whereas the i2 does not.

The RaySafe Real-time Dosimeter: Approximately 1 year of normal use. The battery can be replaced. See the Installation and service manual for guidance.

The RaySafe i2 dosimeter: Typically 3-5 years, depending on usage. If the battery is out, contact your RaySafe representative or RaySafe Support Contact.

R/F high can be used for most measurements and is required for measuring kVp (as opposed to kV).
R/F low is optimized for low radiation intensity, typically during fluoroscopy measurements behind a phantom.

Use the VT305 with the Ansur VT Plug-In. You can use either a ready-for-usetest procedure or drag and drop one or more test elements from the Plug-Inonto the test template workspace in the Ansur software authoring screen(see Ansur Executive Operators' Manual for more information).Questions and Answers6045 Cochran Rd, Cleveland, OH 44139 USA | Tel 440.248.9300 | Fax 440.349.2307 | Email: [email protected] | www.flukebiomedical.com

The Dose Viewer version 1.1.13.0, delivered with the RaySafe i3, is backwards compatible with the RaySafe i2. Older versions of Dose Viewer need to be updated to support i3 Real-time Dosimeters.

The default Excel export format in X2 View is compatible with Xi View.

Unfortunately, this is not possible with the RaySafe i2/i3. This is something that we look in to for the future but currently only the Real-time Display can be used to visualize the exposure situation in real time.

1. i3 badges will enter sleep mode after 9 minutes of not detecting any movement.

• If you just replaced the battery, this means that your ThinX is starting up. Be patient and wait for a while.
• If the screen appears when you are exposing the ThinX to radiation, you need to replace the battery (model CR2450). Follow the instructions in the user manual: ThinX RAD or ThinX Intra. We recommend using a battery from GP Batteries.

• Check that you are running the latest version of Xi View and remove older versions from your computer.
• During installation, make sure to tick the box "Install Windows 8 USB driver for serial port adapter".

• In Xi View, select "ATEN USB to serial bridge" in the lower right corner. You may need to re-select it.

• In Xi View, press the "Start" button in the lower right corner and wait until the dot beside it turns green.
• If you have a Solo instrument, check that you have the RaySafe Solo PC kit.

Note: If your Solo instrument came with serial cable and usb-serial converter, it has the PC kit. If you wish to add the PC kit, contact Customer Service.

Swipe right from the home screen to access the setup. Press the name of the currently connected sensor to find the unit setting.

Note: If only Gray (Gy) is available, your instrument has been configured to comply with German regulations where the unit Röntgen (R) is not allowed.

Yes, they can, i2 and i3 dosimeters will show up on DoseAware base station screens and DoseAware dosimeters will show up on the i2 and i3 base stations screens. As the icons used for dosimeters are not the same for i2/i3 and DoseAware, the dosimeters might however appear differently.

To access the dose history recorded in the Real-time Display, tap on the row for your dosimeter on the display.

To access the internal dosimeter memory, connect the dosimeter to a computer running Dose Viewer.

The RaySafe Xi calculates kVp on the R/F high sensor if the intensity is high enough (around 10 mGy/s), otherwise kV average will be displayed. If the intensity is too low and you have no possibility to increase the tube current (mA), move the detector closer to the X-ray source.
Note: If your signal level is well above 10 mGy/s and you still do not get kVp, go to the SETUP MENU, select kVp mode, and make sure that kV/kVp is selected.

The VT305 uses a single measurement channel for all gas flow assessments.The display's (numeric and waveform screens) are auto-scaling and autorangingfor simple connection and use.

The RaySafe i3 has a customer replaceable battery, which prolongs the product life cycle up to 10 years. The RaySafe i2 badge needs to be replaced when the battery ends in <5 years.

Yes, all common mammography machines are supported. Just connect the X2 MAM sensor and measure to get dose, HVL and time on any beam quality. If you also want the tube voltage (kVp), you must select an anode/filter combination. Swipe left from the home screen to select.

Take a look in the Mammography coverage table to see which anode/filter combinations the X2 can give a kVp value for.

Yes, additional badges are available for purchase.

1. Yes, i3 badges can be set to stay on all the time. This will drain the battery faster, however.

Read "SETUP OF BLUETOOTH COMMUNICATION" on page 6 in the Xi View User Manual. If you have established the Bluetooth communication as described in the User Manual but still have problems, try turning off any programs on the computer that may interfere with the Bluetooth connection. On the computer side, there are various reasons for unstable Bluetooth connection such as incompatible hardware/software or environmental radio disturbances during measurements.

Position and measure as usual. The X2 has full AMX4+ support.

Please visit www.RaySafe.com/i3/downloads, download and install the latest Dose Viewer that support i2 and i3 dosimeters.

No, the intended use for the i3 and i2 systems are to measure scattered radiation only.
