3. If you had chosen Dose earlier, and you have a
Piranha model that supports external dose
measurements you must select the detector you
want to use. If you want to measure dose with the
external probe tap
External , otherwise tap Internal .
4. The Real-Time Display (RTD) is now shown and you are ready to measure, see
figure below. The Piranha is set to the most suitable settings for the selected type of
measurement, in this case radiography. The selected kV-range is 45-125 and the
radiation quality is W/3mm Al (reference radiation quality). Depending on type of
measurement, you may have several kV-ranges and beam qualities to choose from.
For radiography, you have three different kV-ranges (35-75, 45-125, and 90-155) to
select between.You will have four displays on this screen if you do not have/use a
mAs-probe and six if you selected to measure mAs. The manual for the mAs-probe
explains how to connect it.

The first thing to do before starting to measure, is to verify that the Piranha internal
detector is placed correctly in the X-ray field. A special function is available to do this.
