2. Check whether the power supply voltage and frequency variation is within the
allowable rage.
3. Check whether every part of the grounding wire is connected well.
4. Check whether there is any unsafety of all cables.

7.3 X-ray tube warn-up procedures
WARNING: Ensure that the tube is properly warmed-up before efficient X-ray
exposure. Additionally, make sure that no persons will be inadvertently exposed
to unnecessary X-rays during this procedure.
Routine exposures performance will be affected if neglecting to carry out tube warmed-
up procedures. It is recommended that the following procedures will be performed at the
start of each day and when the configure tube has not been in use for approximately one
hour.
Perform x-ray tube warm-up as follows:
◼ Close the collimator blades fully.
◼ Select 70 kV, 100 mAs, 200 mA and 500 ms exposure.
◼ Insure that no person will be exposed.
◼ Make a total of three exposures, 15 seconds apart.
