Figure 5. 75 % trig level activated (figure also applies to 25 and 50 % trig level settings). Please note that
the trig level setting aects the dose measurement.
Single phase generators (normally dental applications) may have slowly increasing amplitude characteristics for
approximately 100 ms. It is then recommended to activate a higher trig level in the SETUP MENU after the first
exposure.
PULSE
The RaySafe Solo counts pulses from 1 to 9999. The trigger to increment the pulse counter occurs when the
dose rate has a negative slope and the amplitude falls below 25 % of the peak amplitude for the exposure. At
peak dose rates of approximately < 3 µGy/s (for R/F low) the signal to noise ratio is too low to count pulses and
“---” will be displayed. If possible, increase the mA and/or kVp to increase the radiation output or decrease the
FDD.
Pulse is available for the R/F, RAD, Dose, DENT and mA/mAs detectors.
HVL HALF VALUE LAYER OPTIONAL
The RaySafe Solo calculates HVL as a function of the signals from several sensor elements from the whole
exposure, if exposure time is less than 6 seconds.
If the exposure is longer than 6 seconds, a HVL value recorded approximately 2 seconds before end trig will be
displayed.
