IMPORTANT WARNINGS
N.B.: These “WARNINGS” are integral part of the instrument
This instrument is to be used STRICTLY for scientific purposes and/or for internal factory control
ONLY.
NOT FOR USE IN RETAIL TRADES. THIS INSTRUMENT IS NOT TO BE USED IN AREAS EXISTING
DANGER OF EXPLOSION.
It is important to note the following points for correct operation of the instrument:
1. Read the technical instructions given in the operating manual carefully. This manual contains
information about installation and use. If these instructions are not carried out carefully, the accuracy
of results may be impaired. If in doubt, please consult the supplier’s engineers.
2. In common with any other electrical equipment, installation should be carried out by a competent
person. In particular:
- ensure that the instrument is correctly earthed;
- do not install the instrument in areas of high fire risk, for example, in the presence of
inflammable gases and vapours;
- switch off and disconnect the power supply before removing any cover;
- do not touch the instrument with wet hands.
3. Install the instrument on a vibration free base and away from draughts or sources of heat. Check the
instrument with test weighing after installation or after repositioning.
4. Avoid connection to a power supply showing high voltage variations due to other loads. The
instrument should not be connected to the same electrical circuit as other high power consuming
equipment as large fluctuations may cause some inaccuracy.
5. The instrument should be checked every 6 months for correct functioning, calibration and accuracy
of the internal calibration mass by a suitable qualified person.
6. A routine calibration check should be carried out each day before use, using a standard mass. This
mass should be indipendently checked monthly.
7. Check the zero function before each weighing operation.
8. If in doubt about any function please call a qualified person. Avoid interference by non-qualified
persons.
9. If the instrument is used for weighing food or drink, ensure that other substances are not weighed on
the unit which might cause contamination.
10. If the instrument is used for weighing chemicals and other similar substances ensure that it is
cleaned and any spillage removed to avoid potentially dangerous reactions.
11. Always clean the instrument after use to avoid subsequent inaccuracies and/or damage to the
equipment.
12. Gibertini Elettronica s.r.l. does not accept any legal liability for damages or other consequences due
to mishandling of the instrument or its accessories.
ADDITIONAL PROCEDURES FOR WEIGHING SUBSTANCE WITH GREAT ACCURACY
Gibertini Instruments are manufactured to be reliable in use with high accuracy. However, reduced accuracy
is always possible due to ambient conditions, incorrect installation or improper use. Where greater accuracy
is required, the following procedures should be observed:
- use modern instruments (manufactured within three years) which are fully checked;
- use certified calibration masses before each weighing operation;
- make at least two measurements;
- install the instrument in a draught-free, constant temperature cabinet:
- consider the use of two instruments installed together and make weighings on both units,
otherwise use calibrated masses with a certificate of calibration from a recognised institute.
All electronic balances, which are sensitive to changes of gravity, must be checked and calibrated in
the place where they are to be used.
ALL OUR INSTRUMENTS MEET INTERNATIONAL EMC-EMI-RFI standard s according to 2004/108
EEC Directive on Electromagnetic Compatibility.
