KERN & SOHN DS - Manual (Page 22)

3 Fundamental information (general)
It is essential to read through and observe the complete operating instructions before in-
stalling and commissioning.
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 re-
moved 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 application/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 regular intervals within the scope of quality assurance. For this purpose, the
answerable user must define a suitable 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 ac-
credited DKD calibration laboratory (return to national normal).
