Barracuda & QABrowser Reference Manual
The MAS-2B probe is mostly used for
mAs measurements since it is not
sensitive enough to measure tube
current on fluoroscopy. The lowest tube
current that can be measured with
MAS-2B is 10 mA. The figure to the left
shows the MAS-2B probe without the
cable. Read the MAS-2B User's Manual
for a detailed description and instructions
on how to set up and connect it.
The parameter mAs is available for most type of measurements but mAs is normally
measured only for X-ray exposures.
