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. At start up (after the
battery status information), valid Trig delay, kVp delay and Calc. delay are displayed in sequence.

(Factory settings in bold.)

Trig delay

A delay in ms after the normal trig of the RaySafe Xi. Utilize when an unwanted part
of an exposure, such as a pre-pulse, should be excluded from the measurement. No
measurements are performed during the Trig delay. (0, 5, 10, 50, 100, 200, 500, 1000,
2000 ms)

Trig level

Use Trig level to measure correct exposure time on waveforms with slowly increasing
output, such as with single phase dental. The default setting is a low value, that
depends on the selected sensor; see Specifications. Can be set to 25, 50 or 75 % of
the peak value of the previous exposure. Use it with the same generator settings and
FDD. Not selectable before the first exposure or at low dose rates.

kVp delay

Defined as the delay in ms, after the trig delay, but before the radiation and kV
waveform window (in the RaySafe Xi View) begins. (0, 2, 5, 10, 50, 150, 300, 1000,
1200, 1500, 1700, 2000 ms)

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 2 s when measuring on generators with a pre-pulse. (0.5, 2,
4, 6, 7s)

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)
