5. Measurements with the Barracuda System
Tube Current Probes

5.9.1 MAS-1B, Invasive mAs Probe
This section describes how to measure the tube current and charge as a single
parameter. This means that the measurement starts when the mAs-probe detects the
tube current. The measurement is performed in the same way if you use a
multi-parameter display. In that case the default trig is the MPD and what is said below
about false triggering can be ignored.
The MAS-1B probe provides an invasive
way to measure mA and mAs on X-ray
generators. The MAS-1B probe should be
connected to the X-ray generator mAs
socket. The figure to the left shows the
MAS-1B. Read the MAS-1BUser's Manual
for a detailed description on how to connect
it.
To measure tube charge (mAs) with the MAS-1B
1. Connect the MAS-1B probe to the X-ray generator as described in the MAS-1B
User's Manual.
2. Connect the MAS-1B probe to the EMM module.
3. Set up the Barracuda and the handheld computer according to the description in
Setting Up the Barracuda .
4. In the QABrowser select type of
measurement.
5. Select mAs from the menu.
5A. The Select Detector screen is now
displayed. Select the MAS-1B probe as
shown left, and tap Select.
