Barracuda & QABrowser Reference Manual
If you get the trig indicator ("play" symbol) when there is no signal:
1. Press reset.
2. If it comes over and over you may need to increase the trig level, by raising the
threshold, see topic Settings .
The electrometer or MPD gives too low dose rate
If you get to low dose rate readings or too short irradiation times for short exposures:
1. Check that you are measuring with a good geometry, where the incoming radiation
is perpendicular to the detector surface. See Specifications, MPD for details.
The QABrowser does not show the Bluetooth "Discovery Results" screen
Try the following:
1. Exit the QABrowser.
2. Do a hardware reset of your Tungsten (using the reset hole on the back of the
Palmtop).
3. Restart the QABrowser.
A HotSync was performed to install a new version of QABrowser but it does not
seem to have been installed
The reason can be that wrong Palm user name has been used.
1. Open Palm Desktop and select edit users in the upper right corner.
2. Tap the HotSync icon on the Palm, the user name can be seen in the upper right
corner.
3. If the user name is not in the list in Palm Desktop, perform a HotSync to
automatically add the user name. If it is in the list, go to number 4.
4. Restart the QABrowser Updater and select the Palm user name corresponding to
the Palm that you intend to use.
Installation or upgrade of RTI Updater failed
Make sure you are not having a restricted user account (on Windows XP or 2000).
You will need to have access to an administrative account to install the software, see
section Windows Restricted User Accounts for details.
I get a blank white screen when running the QABrowser
Click the Back button (leftmost) to get out and then re-enter the test again.
Bluetooth unable to reconnect using Retry
Tap Exit and restart the Barracuda and then re-start the QABrowser again.
Bluetooth only shows "Unknown device" when trying to connect
Depending on Palm model it may take a little while for the serial number to appear,
the Barracuda will appear as "Unknown device". Normally it will show the serial
number if you wait a while.
How do I change from Gray to Röntgen units?
You can set this for all tests (pull-down menu | Setup | Units), see Units Setup .
It is also possible to set mixed units for a test and save as Favourites . All
measurements settings, QABrowser settings, set values, and selected units will be
saved with the Favourite.
How do I stop the units from autoscaling its prefixes?
