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.

It is enough to measure kV for one beam quality per machine, since the set kVp is independent of anode material and filtration. The Mammography coverage table lists what you can measure on different machines.

The Compliance parameter shown on the FULL (full test) numeric display ofthe VT PLUS is a dynamic value calculated from tidal volume and pressurevalues breath-by-breath. The Cstat parameter shown on the VT305 is a staticcompliance parameter calculated using the formula Cstat = VT / (Pplateau -PEEP) where Pplateau is the Inspiratory Pause Pressure. Not all ventilatorsprovide an inspiratory pause/hold function. If there is no plateau pressure,the VT305 Cstat displays"---" since a division by zero would result.

The EMC immunity in the i3 has been significantly improved over the i2, reducing possible interference.

Real-time measurements from up to eight dosimeters are shown simultaneously on the screen. The i3 has a sleep mode so only active dosimeters user show on the screen. The i2 dosimeters are always on and shown on the screen when in range.

Display: Luminance mode. For contact measurements on a display or view box.

0: Zero adjustment.

Light bulb: Illuminance mode. For measurements of ambient light or intensity from a collimator lamp.

1. Prolonged life cycle
2. improved EMC immunity
3. better measurement specifications
4. automatic sleep mode
5. improved wearability.

CRC error means that part of the data has been lost or altered in transit. This can happen when the distance is too long, or if something is interfering with the signal. Create a clear line of sight between the base unit and computer, or use a shorter distance.

The DXR+ works well placed on the examination table. Use as high kV as possible.

Note: Do not position the DXR+ on top of a magnification table, since the signal is too low there.

Press the desired parameter from the home screen to go to full screen mode, then swipe left for the waveform. Waveforms are available for kVp, dose rate and mA.

Yes, you can.

Place your CT detector on a flat surface and restart the base unit. Do not touch or move the detector. If the "Stabilizing" message does not disappear within 5 minutes, fill in a Service Request and send the detector for service.

To save measurements press and hold the "O" button at the upper rightcorner of the VT305 display until the "Data saved toDATAxx.CSV" message is displayed on screen. This meansthat the measurement values have been saved to the microSD card in the VT305.

The i3 measurement performance is an improvement over the i2, and includes angular reception making it more accurate.

The real-time display can be installed anywhere, it only needs a power outlet (network connection is optional). The dosimeters communicate with the display via radio. The radio communication range depends on the local environment and the Real-time Display settings (Service Manual) but is normally about 5-15 meters.

The X2 Base Unit can store several thousands of measurements.

• Swipe down from the home screen to see previous measurements.
• If the base unit has been turned off, or if you have switched to a different sensor, look in the measurement archive: Press the menu button and then Measurement archive. Select the session you want to take a look at.

• You can also use X2 View on a computer and select Import from Base Unit in the File menu and select from the calendar. See the X2 View manual for more details. 

To update firmware in the VT305 do the following:1. You will receive an update file (e.g. filename C0204000.S19) fromFluke Biomedical.2. Remove the micro SD Card from the VT305 and insert the card into your PC.3. Copy the update file onto the microSD Card.4. Remove the micro SD Card from the PC.5. Insert the micro SD Card back into the VT305.6. Restart the device (power on the VT305).7. The screen will show you the update's progress8. When the update is finished, the device will restart by itself.

No, you have to send it to RaySafe for battery replacement. Fill in a Service Request to get it done.

The user manual for X2 is called "Help" and is integrated in the base unit. Press the menu button on your base unit and then "Help" to see the user manual for your system. You can also find video tutorials and pdf-manuals on the Product support page.

Yes, can combine i2 and i3 badges but be aware that measurement results may differ. We recommend that you replace the i2 badges with i3 ones as soon as possible to increase the efficiency of your RTSD.

Offset out of range is shown when the current in the ionization chamber fails to reach a stable level. Please make sure that:
the chamber is not irradiated during the stabilization or zero adjust phase, you are operating the instrument within its specified temperature range (15-35 °C).
If the problem persists, fill in a Service Request and send the detector for service.
I get too low readings with my Light detector. Why?

To retrieve measurements from the VT305 micro SD card:1. Remove the micro SD card from VT305 andinsert it into the appropriate SD card adapter(provided as a standard accessory with theVT305).2. Insert the micro SD card and SD card adapterinto the SD card reader, or insert the micro SDcard into the USB SD card adapter (providedas a standard accessory with the VT305).3.

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.

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.

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

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?
