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 instrument. 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 kVp measurement (and
waveform) window begins. Use a kVp delay on machines with slow rising output,
such as single phase intra oral machines and fluoroscopy systems. (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 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. (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 Solo 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 the instrument 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.
not applicable for RaySafe Solo dose.
