KERN & SOHN CDS - Manual (Page 9)

3 Basic Information (General)
It is absolutely necessary that you read and understand the operating instructions prior to installation and
commissioning and follow the instructions during the process!
3.1 Proper use
The balance you purchased is intended to determine the weighing value of 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. As soon as a stable weighing value is reached the weighing value
can be read.
3.2 Improper Use
Do not use balance for dynamic weighings. 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 permanent load on the weighing plate. This may damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly existing
tare load, must be strictly avoided. Balance may be damage by this.
Never operate balance in explosive environment. The serial version is not explosion protected.
The structure of the balance may not be modified. This may lead to incorrect weighing results, safety-related
faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of use must be released by
KERN in writing.
3.3 Warranty
Warranty claims shall be voided in case
- Our conditions in the operation manual are ignored
- The appliance is used outside the described uses
- The appliance is modified or opened
- mechanical damage and damage caused by media, liquids
- natural wear and tear
- The appliance is improperly set up or incorrectly electrically connected
- The measuring system is overloaded
3.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the
testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type
and scope of this test. 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. Our accredited DKD calibration
laboratory offers fast and inexpensive adjustment for test weights and weighing balances (reset to national
normal weight).
