ABOUT THE X2 SYSTEM
The RaySafe X2 consists of a base unit, sensors and the X2 View computer software.
The sensors options are:
R/F, for radiography and fluoroscopy measurements, with or without a phantom between the sensor and the
X-ray source.
MAM, for all kinds of mammography measurements.
CT, an ionization chamber for measurements on CT dose applications.
Light, for illuminance measurements and luminance measurements on monitors and light boxes.
Survey, a sensitive sensor for measuring leakage and scattered radiation, as well as other applications with
low dose rate.
mAs, an integrated tube current meter.
X2 View is a PC software for use with the X2 instruments. In X2 View, you can view measurements and waveforms
on a larger display, store measurements, transfer data to Excel or other software and get software updates for the
base unit.
When you want to measure, all you need to do is:
1. Turn on the base unit
2. Connect a sensor
3. Position the sensor
4. Expose
For more detailed information, see the help chapter for each sensor.

NAVIGATE THE BASE UNIT
The base unit has a touch screen and three buttons.
Swipe up and down on the home screen to access your previously recorded measurements. Swipe right from the
home screen to go to the setup screen, from which you can make settings and view information about the system,
for example the calibration date for a connected sensor. Tap on a parameter to get larger digits, one parameter at
a time. You can also measure in this mode. From the single parameter screen, you can swipe right to view the
measurement specifications, and left to see waveforms, if available.
The three buttons below the screen are:
Menu, brings up a menu on the screen
Home, takes you to the home screen
Back, takes you back to the previous screen
On the back side of the base unit are:
Reset switch, for forced reboot of the base unit
Charger/PC connector, for charging or using with a PC with X2 View
mAs connector, for tube current measurements
Two sensor connectors
Ethernet connector, for future use
On/Off switch. Press the button shortly to enter sleep mode. After a while in sleep mode, the base unit will
turn off automatically. Press the button for 2 seconds to turn off the base unit immediately.

VIEW MEASUREMENT
Swipe up or down to scroll between measurements. Tap on a parameter to get larger digits. Swipe right to access
the parameter information with measurement specifications. Swipe left to view a waveform, if available for the
current parameter.
Press the menu button and select Notes to access more information about the measurement and to be able to add
a note.

ACCESS ARCHIVED MEASUREMENTS
Measurements from previous sessions are automatically archived in the base unit. The memory allows about 10000
measurements. When the memory is full, the oldest measurements are automatically deleted.
The measurements are sorted by date and time.
VIA BASE UNIT
To access archived measurements, press the menu button and select Measurement archive. Select a session to
see the individual measurements for that session. Swipe up or down to scroll between measurements.
VIA X2 VIEW
To access archived measurements via X2 View, connect the base unit to a computer running X2 View and select
Import from base unit under the File menu.

CHANGE PARAMETER VIEW
To change the number of parameters showed on the home screen, press the menu button and select Change view.
There are two views to toggle between:
All measured parameters, or
Four key parameters of your own choice. Press and hold on a box to select which parameter to show.

ANALYZE WAVEFORMS
View a single parameter by tapping on that parameter on the home screen. Swipe left to go to the waveform
screen.
The dark line represents an average of the measured values. If
there are more values than possible to show on the screen, the
light blue pixles represent the range of these values.
The dashed lines indicate the measured parameter values, in this
case average dose rate and time.
Tap on the button in the upper right corner to analyze the waveform.
Slide the handles to view, for example, the peak dose rate of a
pulse.
Pinch with two fingers to zoom in the waveform area.
Tap the button again to exit the analyze mode.

CONNECT THE BASE UNIT TO A COMPUTER
Connect the base unit to a computer running X2 View using a USB cable (recommended length: max 2 m). X2 View
can be installed from the X2 View CD, that came with the system.
If you measure, the results will automatically show up in X2 View.
You can also select Import from Base Unit in the File menu to import measurements stored in the base unit.
From X2 View, you can export measurements to Excel and other software. For more information, see the X2 View
help, reached from the Help menu in X2 View.
