4 Basic Information (General)
4.1 Intended 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
pan. As soon as a stable weighing value is reached the weighing value can be read.
4.2 Improper Use
Do not use balance for dynamic add-on weighing procedures, if small amounts of
goods to be weighed are removed or added. The “stability compensation“ installed in
the balance may result in displaying an incorrect measuring value! (Example: Slowly
draining fluids from a container on the balance.)
Do not leave permanent load on the weighing pan. 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
damaged 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 f ault s and des tr uct ion 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.
4.3 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 or damage by media, liquids, natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
8 ADB_ADJ-BA-e-2032
4.4 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. In
KERN's accredited DKD calibration laboratory test weights and balances may be
calibrated (return to the national standard) fast and at moderate cost.
5 Basic Safety Precautions
5.1 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.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
6 T ransport and storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
6.2 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.
Pack weighing plate + accessories and power supply unit
separately.
Secure glass windshield against slipping (e.g. using an
adhesive strip).
