Conditions - Beam Correction
Sometimes you may want to make comparable
measurements with known mechanical setup. For
instance if you want to emulate ion chamber
measurements in a particular scattering situation. Then
you can set a
Beam Correction factor
to get that
reading. In this case the ion chamber measures an extra
25 % from side and back-scatter. Using this factor
makes the readings to be the same. It is of course
important that the mechanical setup in these cases are
the same. When this function is activated a red
horisontal indicator will show in the top right corner of
the RTD screen (
).
Here you can see an example of
a holder that is used for some
customers to replace ion
chambers in ready-made fixtures.

Settings - Piranha
Here general measurement settings for the Piranha are
shown.
Post Delay
The post delay time defines how long time the Piranha shall wait
and "look for more" after detecting what can be considered to be
"the end of the exposure". Default value is 250 ms. The post-delay
is necessary when measuring on units with some kind of pre-pulse
or for pulsed exposures.
The post delay can be set to:
Off, 25 ms, 250 ms, 1 s,
or
Other…
(0-9999 ms).
The default value is set according to selected type of
measurement, see section
Measurement Type Settings
.
