Warming-up of X-ray tube
The X-ray tube needs to be warmed-up before making X-ray exposures at the
start of each day and when the X-ray tube has not been in use for more than an
hour. This extends the X-ray tube lifetime.
To warm-up the X-ray tube
1. Close the collimator blades fully
2. Set exposure settings: 70 kV, 100 mAs, 200 mA, 500 ms and large focus
3. Ensure that no one will be exposed
4. Make a total of three exposures, 15 seconds apart
This procedure is used for a typical X-ray tube. Consult the X-ray tube
manufacturer instructions for the actual X-ray tube in use and comply with the
instructions if there is conflict with this procedure.

Conditioning procedure for the X-ray tube
If the X-ray tube has not been used for more than a week or if exposure
techniques are to be used with energies above 120 kV, it is recommended to
perform the conditioning procedure for the X-ray tube.
A sequence of gradually increasing loads on the X-ray tube will cause a
redistribution of the electrical charges inside the tube, which in turn will
result in a stable output of the tube.
The procedure takes approximately 30 minutes.
1. On the software console, select the manual modality positon.
No image will be acquired on the NX workstation.
2. Select the three point radiographic working mode.
3. Set the radiographic parameters to 125 mA (current) and 100 ms
(exposure time).

and the service to be informed. The equipment must only be put
back into operation when the fault has been repaired.
