This Test procedure verifies the TTS functionality (VA requirement) It has to be checked manually if the heat indicator of the Generator produces an alarm within the specified range. The tube has to be in a cold situation, to ensure that the measurements are reproducible. (at least 4hour after the last examination).

The collimator has to be closed and covered with lead. To protect the tube it is possible to select the simulation mode, that means no X-ray is generated , but the TTS calculation is active. The settings are tube dependent and has to be found in the Generator Manual Section "Adjustments"

After finishing switch off the simulation mode.
