figure 1 illustrates the RaySafe Solo parameter definitions available on a typical waveform. In most situations 
the default settings are suitable for accurate measurements. In certain situations advanced users can change 
the measuring definitions of the RaySafe Solo by activating trig delay and/or trig level settings. Because the 
measured parameters will be affected by the settings of delays and trig levels, it is recommended to note the 
setup information shown on the base unit display at power on.
Figure 1. Normal Measurement
When an exposure exceeds 4 seconds the measured values are continuously updated in the display. It may 
take another few seconds to get stable readings (synchronized with the frame rate).
doSe
the RaySafe Solo R/f, MAM, MAM dose, RAd, dose and dent detectors measure dose with a multi-segment 
sensor, and the Active compensation feature automatically corrects the displayed dose (and dose rate) for 
beam qualities with an hVl of 1 – 14 mm Al (for example: a filtration of 45 mm Al at 140 kVp gives an hVl of 
about 13 mm Al).
the Ct meter is an ionization chamber with carbon fibre housing. It has a flat energy dependence curve and 
automatic pressure and temperature correction.
