RaySafe Xi - Manual (Page 13)

Dose unit Change the default units and/or use this feature to recalculate a value to a different unit.
(Gy or r per s, m or h, where 1 Gy = 114.1 r.)
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.
kVp Mode “kV only” prevents raysafe Xi from calculating kVp, which otherwise occurs
automatically when r/f high is selected and the signal level is high enough (“kV/kVp”).
useful for example when measuring near that signal level.
