1. Protection from radiation
From the first use of the X-ray apparatus to the last,
you must ensure that any planned use is in con-
formance with local legislation, stipulations and
regulations and has been approved by the respon-
sible authorities or otherwise certified.
High voltage may only be applied when the cover is
closed and the safety circuitry is correctly con-
nected and activated. Only when this has been
done can the X-ray apparatus be operated. The
housing is secured against unauthorised opening
by means of a self-tapping screw. This prevents X-
ray radiation from escaping and allows experi-
ments to be performed in safety.
The maximum operating parameters
U
= 30 kV and
I
= 100
μ
A must not be exceeded.
Every time the X-ray apparatus is used, the radia-
tion protection equipment must be checked as
specified in Section 8.1.
Never open the housing of the X-ray apparatus. Any
attempt to manipulate, repair or otherwise tamper
with the equipment other than setting it up for use
in a laboratory invalidates the certification for this
type of equipment and it may no longer be used
for any purpose. Repairs may only be made by the
manufacturer UK 3B Scientific Ltd.
•
The apparatus must be secured in such a way
as to prevent unauthorised access.
2. Safety instructions
The X-ray apparatus conforms to safety regulations
for electrical measuring, control and laboratory
equipment as specified in DIN EN 61010 Part 1 and
is designed to meet protection classification I. It is
to be operated in dry rooms as appropriate for the
use of electrical equipment.
Safe operation of this equipment is guaranteed as
long as it is used as stipulated. However, there is no
guarantee of safety if the equipment is used incor-
rectly or carelessly. If there is any suspicion that the
equipment can no longer be operated without risk
(e.g. if visible damage is detected), the equipment
must immediately be withdrawn from use and
secured in such a way as to prevent its inadvertent
operation.
•
As soon as you have unpacked the X-ray appara-
tus, check it for any signs of damage that may
have occurred during transport. If any damage is
found, do not attempt to operate the equipment
but inform the manufacturer UK 3B Scientific Ltd.
•
Please do not dispose of the packaging, since it
might be handy should you need to return the item.
•
Before using the equipment for the first time,
ensure that the mains voltage selector switch is
set to the right voltage.
Due to the high dosage potential inside the X-ray
apparatus, users are obliged to treat the equip-
ment with special care.
•
Before any use of the X-ray apparatus, the
housing, the cover plus the control and display
elements should all be checked and in particu-
lar the radiation protection equipment must
be checked as specified in Section 8.1.
•
If any damage is found, the equipment must
immediately be withdrawn from use and se-
cured in such a way as to prevent its inadver-
tent operation.
•
If any malfunction occurs, the equipment must
immediately be withdrawn from use and se-
cured in such a way as to prevent its inadver-
tent operation.
•
If the high voltage indicator lamp is lit even
though the cover has not been fully closed and
locked in its central position, the equipment
must immediately be withdrawn from use.
If the cathode heater filament of the tube is not oper-
ating, then no “afterflash” (spark discharge of the tube
heater filament on disconnection of high voltage) can
take effect when the high voltage supply is turned off.
In this event, a high voltage can remain in effect in
the tube for up to 6 hours after disconnection.
•
For this reason you should not touch any of the
high voltage terminals for at least 6 hours after
failure of the cathode.
•
When replacing bulbs or fuses, always discon-
nect from the mains.
