Please read this information carefully before putting the
device into service!
This device has been built and tested according to the IEC 1010 safety standards for
electronic measuring instruments and has left our works in a condition complying with
all the requirements of technical safety.
The perfect functioning and operational safety of the instrument can only be ensured
if the user observes the normal safety precautions as well as the specific safety
guidelines stated in the present operating instruction.
- Before connecting the plug-in power supply unit to the electricity supply network,
it must be ensured that the operating voltage stated on the plug-in power supply
unit corresponds to the mains voltage (statement of the supply voltage range).
- Attention. Magnetism! Effects of the magnetic field have to be taken into account
(e.g. data carriers, cardiac, cardiac pacemakers...).
- The perfect functioning and operational safety of the instrument can only be
maintained under the climatic conditions specified in the "Technical data" section
of these operating instructions.
- When the instrument is moved from cold to warm surroundings, condensate may
occur and interfere with the functioning of the instrument. In such a case, the
user should wait until the temperature of the instrument has adapted to the
ambient temperature before using the instrument again.
- Balancing, maintenance and repair work must only be carried out by a suitably
qualified technician authorized by us.
- If there is reason to assume that the instrument can no longer be employed
without a risk, it must be set aside and appropriately marked to prevent further
use.
- The safety of the user may be endangered, e.g., if the instrument
ƒ shows visible damage,
ƒ no longer operates as specified,
ƒ has been stored over a longer period under unsuitable conditions,
ƒ has been subjected to difficult conditions during transport.
- If in doubt, the instrument should as a rule be sent back to the manufacturer's -
"Wissenschaftlich-Technische Werkstätten GmbH" - for repair and maintenance.
