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.

I get "Offset out of range" with my CT detector. What can I do?

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.

Does the i3 have a cradle for connecting the dosimeter to the computer?

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.

Does the dosimeter accumulate dose even when there is no Real-time Display nearby?

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.

Where is the active sensor area on the different X2 sensors?

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

X2 Sensor active 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.

Can I use DXR+ for measuring a CT dose profile?

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

How do I ensure that I get the full battery-use-per-charge with VT305?

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.

I have problems with my Bluetooth connection. What can I do?

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.

What is Dose Manager and what does it do?

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.

Are the i3 badges legal dose of record?
  1. No, i3 badges are not legal dose of record. The readings they record should be used for reference and behavior modification.
I get too low readings with my Light detector. Why?

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?

Can I charge the base unit with the USB cable to my computer?

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.

If an aspect of the dosimeter badge such as the clip breaks, do I have to replace the entire badge?

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

Do I need to send the dosimeter in for calibration?

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

How do I change the dose unit?

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.

What do I do if I need to keep testing when I get a low battery indication on the VT305?

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.

I want to measure on a panoramic dental X-ray machine. Any advice?

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.

Panoramic Holder

 

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

Can Dose Manager be used with the new i3 dosimeters?

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.

Does the system sound an alarm when dose gets high?
  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.
