After an offset adjustment, the RaySafe Xi is in MEASURE MODE. The displayed value is updated after each
exposure.
Dose
Dose Length Product
NOTE! The RaySafe Xi CT detector can be used in two dose modes (dose or dose length product
(DLP)), selectable in the SETUP MENU. Since the RaySafe Xi CT chamber is 10.0 cm long, DLP
readings (in Gy•cm or R•cm) will always be exactly 10 times higher than dose readings.
3. SETUP MENU
Press SELECT to enter the SETUP MENU (from MEASURE MODE) and STEP to step between setup
parameters.
All values are stored in a non-volatile memory and are valid until manually changed. (Factory settings in bold.)
Calc. delay Defined as the dead time after end trig, before data is calculated. Default is 0.5 s but it is
recommended to use a longer delay when measuring on pulsed fluoroscopy where the
time between pulses may exceed 0.5 s. (0.5, 2, 4, 6, 7 s)
Dose unit Change the default units and/or use this feature to recalculate a value to a different unit.
(Dose: Gy, Gycm, R or Rcm, Temperature: °F or °C, Pressure: kPa or mmHg)
Backlight Display lighting option. (off, 2, 5, 10 s, on)
Auto Power Off Never, or after 5, 20 or 60 minutes of inactivity.
Info Displays the serial number (S/N) and firmware version of the connected detector and
the RaySafe Xi base unit and the calibration date for the selected sensor. There is also a
possibility to reset the instrument settings to factory defaults.
