6 Operation
NOTICE
Short circuit due to build up of con-
densation
• The appliance can only be put into
operation once it has warmed up to
room temperature and it is dry .
The necessary tests (e . g . acceptance test) are regulated by the locally applicable national law .
• Find out which tests are to be made .
• Carry out tests in accordance with national law .
6.1
Acceptance test
When carrying out the commissioning
tests where the image plate and sensor
are used as receivers, the 2-D X-ray test
phantom is required and possibly the
appropriate 2-D X-ray test phantom
holder .
• Before commissioning, carry out the acceptance test of the X-ray system according to national reg-
ulations .
• The tests of constancy, that must be carried out at regular intervals by the personnel, are based on
the results of the acceptance test .
6.2 Electrical safety check
• Carry out an electrical safety check according to all national regulations (e .g . patient conductivity,
conductivity of housing) .
• Document the results .
6.3 Switch unit on
The display will show the standard values for X-ray exposures or the setting values used for the last
exposure carried out .
– Operational display lamps,
– LED for menu tooth symbol,
– LED for menu Adult/Child and
– LED for menu image plate/sensor all light up .
6.4 Generator Warm-Up
If the x-ray generator has not been used within the last 1 month, then a tube warm-up procedure
should be performed to prolong tube life . Set mA to '4', kVp to '60' and exposure time to '2 .0' Sec .
Repeat three times . This procedure will heat the anode uniformly so that higher subsequent expo-
sures will not damage it .
