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).

4 Basic Safety Precautions
4.1 Pay attention to the instructions in the Operation Manual
Carefully read this operation manual before setup and commissioning, even
if you are already familiar with KERN balances.
Versions in other languages are non-binding translations.
The only binding version is the original document in German.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking
for possible visible damage.
In case of visible damage have the damage verified by the messenger’s signature. Do not alter goods or
packaging and do not remove any parts of the delivery. Report the damage immediately (within 24 hours) in
writing to the parcel service.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove loose/mobile parts.
Reattach possibly supplied transport securing devices.
Secure all parts such as the glass wind screen, the weighing platform, power
unit etc. against shifting and damage.
