QA BEAMCHECKER™ PLUS 76
Possible Cause 4:
If using the Serial to USB Adapter with a laptop computer, the laptop may need to be plugged
into a wall outlet with a grounded power supply. If the laptop does not have a grounded
power supply, please contact Standard Imaging for more information. See Tech Note 4050
available at www.standardimaging.com for additional information.
Possible Cause 5:
A Serial to USB Adapter is being used, but the drivers have not been setup. The Serial to USB
Adapter will NOT work without the correct device driver installed on the PC. Check the
adapter packaging for a CD or DVD ROM that contains the device driver installer. You may
also check the manufacturer website and download the correct, latest device driver installer
for the USB to Serial Adapter. Consult the instructions included with the adapter to ensure
proper driver setup.
The QA BeamChecker Plus Connection Status is shown as “Not Synchronized” by the Communication Software
See the About Synchronization and Database Relationship section of this manual for more
information.
There is no place to connect the QA BeamChecker Plus or Power/Data Cradle to the PC.
Possible Cause 1:
The computer does not have a serial port. Some notebook or small form factor computers no
longer have the 'legacy' physical serial port. Several 3rd party companies manufacture
adapters which allow connection of a serial device through a USB port. Standard Imaging
highly recommends use of the provided Serial to USB Adapter (REF 70503) for best assurance
of a reliable serial connection. Contact Standard Imaging for pricing and purchasing
information if you no longer have one. If a USB connection is not available, an internal PCI
serial port add-on card or USB hub may be used. Consult the computer manufacturer for
more information.
When taking measurements in Wire-Free mode, fault code ‘XXX’ appears on the QA BeamChecker Plus front
panel status display.
Possible Cause 1:
A baseline has not been acquired for the detected energy or the measured energy is outside
of the automatic detection tolerance. Ensure a baseline measurement has been acquired for
the attempted energy. Being out of tolerance is typically caused by a baseline being acquired
at a much different time of day compared to the time of day that the daily QA data
measurements are taken. Due to accelerator warm-up considerations, it is recommended to
acquire baselines in similar conditions and time of day of daily measurements for best results.
See page 12 for instructions on how to create or recreate baselines.
Possible Cause 2:
The QA BeamChecker Plus is not flipped to the proper side or the MODE / PLAN switch has
not been pressed to indicate the correct orientation. Ensure that the proper side faces up on
the QA BeamChecker Plus when placed on the treatment couch. The text on the field label
