3. Tap Hold to acquire waveforms. The third screen displays the waveform for the
earlier screen.
4. Tap Hold again to "release" the display.
5. The last screen above shows actually the same measurement with added 10 mm
filter to reduce the dose rate even further. Note that the kV value is the same since
the Piranha, even on this extremely low level, still makes corrections for the beam
filtration.
The Piranha can measure both kV and dose rate at very low levels for instance on Mini
C-arm systems. Piranha can (as an example) successfully measure the tube voltage as
low as 43 kV with a 25 µA tube current.
