Trig source
This setting makes it possible to define the trig source for the
electrometer module.
Available settings are:
Individually
, each detector starts to measure individually when
it detects a signal.
Internal detector
, the measurement of all parameters (all
modules) start when the Internal detector starts to measure.
Default value is always Internal detector when it is used. This is the
recommended trig source.
Trig level (time)
Here you can set the level used for irradiation time measurements.
"Trig level (time)" (TL) is normally set to 50 % of the peak
waveform (S
PEAK
), but can be set between 10 and 90 %. The
irradiation time is then calculated as the end time minus the start
time.
The start time is the first time the signal goes above TL×S
PEAK
.
The end time is the last time the signal goes below TL×S
PEAK
.
See example below.
Update
This setting defines when Piranha shall send measured
values to the QABrowser.
Four different alternatives are available:
After
exp
., the QABrowser receives a new value
when the exposure terminates.
Continuous
, the Piranha is continuously sending data
as long as radiation is detected. Displays in the
QABrowser are updated about every four seconds.
Typically used for Fluoroscopy.
Timed
, the user sets a measurement time. The user
then starts the measurement and the Piranha will
measure all radiation received during the
measurement time, without any trig levels. When the
time has passed, a reading will be presented.
Free run
, the Piranha will continuously measure the
radiation without any trig levels.
