3. Set kVp and mAs (or mA/time) to the desired values.
4. Make an exposure. The RTI logo flashes
to indicate that the MPD has detected the
exposure.
5. Read the values. As complementary
information the dose rate and exposure
time is also displayed below. Tap Wave to
view the corresponding dose rate
waveform.
6. Repeat the measurement for other generator settings or select an application to

5.3.3 HVL Application
HVL is calculated in the standard way using an
HVL stand and a set of aluminum filters.
The general HVL method that can be used when
measuring with an external detector connected to
the electrometer module is described in section
HVL & Total Filtration .
Using the MPD and the built-in HVL application
correct HVL value and total filtration value can be
measured and calculated.
