The single parameter displays are large to allow reading from distance. In the single
parameter displays complementary values may be shown (in the figure above exposure
time and total filtration). Which complementary values that are shown depends on the
selected parameter. Up to three complementary values can be shown.
If any of the displayed values is not possible to compensate or cannot be measured with
full accuracy the symbol is displayed at the top of screen. If the symbol is displayed
you can tap it with the pen to display more information.
3.3.2 Waveforms - Acquiring and Viewing
Waveforms are always captured for each exposure you make. Up to three waveforms
are simultaneously captured and visualized with the QABrowser. The following
waveforms can be measured depending on configuration and selected type of
measurement:
tube voltage (kVp) with the Internal detector
dose rate with the Internal detector
dose rate with the external Dose Probe (available for specific Piranha models).
tube current (mA) with the external Dose Probe (available for specific Piranha
models).
In Continuous update mode you also have the possibility to restart the waveform
collection during the measurement. Every time you tap Hold, the waveforms are
acquired again. When you do this, the previously acquired waveforms will be replaced.
The waveforms available for viewing will be the ones from you last Hold tap.
To view waveforms after the exposure:
1. Tap Wave (or press the corresponding
button). The waveform screen appears and
waveforms are displayed. The kV waveform
takes a few seconds to calculate before it is
displayed.
