3 Fundamental information (general)
It is essential to read through and observe the complete operating instructions before installing and commis-
sioning.
3.1 Intended use
The balance you have acquired serves to determine the weighing value of the material to be weighed. It is
intended to be used as a “non-automatic“ balance, i.e. the material to be weighed is manually and carefully
placed in the centre of the weighing plate. The weighing value can be read off after a stable weighing value
has been obtained.
3.2 Inappropriate use
Do not use the balance for dynamic weighing. In the event that small quantities are removed or added to the
material to be weighed, incorrect weighing results can be displayed due to the “stability compensation“ in the
balance. (Example: Slowly draining fluids from a container on the balance.)
Do not leave a permanent load on the weighing plate. This can damage the measuring equipment.
Be sure to avoid impact shock and overloading the balance in excess of the prescribed maximum load rating
(max.), minus any possible tare weight that is already present. This could cause damage to the balance.
Never operate the balance in hazardous locations. The series design is not explosion-proof.
Structural alterations may not be made to the balance. This can lead to incorrect weighing results, faults
concerning safety regulations as well as to destruction of the balance.
The balance may only be used in compliance with the described guidelines. Varying areas of applica-
tion/planned use must be approved by KERN in writing.
3.3 Guarantee
The guarantee is not valid following
- non-observation of our guidelines in the operating instructions
- use outside the described applications
- alteration to or opening of the device
- mechanical damage and damage caused by media, liquids
- natural wear and tear
- inappropriate erection or electric installation
- overloading of the measuring equipment
3.4 Monitoring the test substances
The metrology features of the balance and any possible available adjusting weight must be checked at regu-
lar intervals within the scope of quality assurance. For this purpose, the answerable user must define a suit-
able interval as well as the nature and scope of this check. Information is available on KERN’s home page
(www.kern-sohn.com
) with regard to the monitoring of balance test substances and the test weights required
for this. Test weights and balances can be adjusted quickly and at a reasonable price in KERN’s accredited
DKD calibration laboratory (return to national normal).
