3. General Safety Instructions
3.1 Duties of the owner-operator
Follow national accident prevention regulations and all operator health and
safety at work and operating regulations.
The balance may only be used for the proposed purpose. Any type of use which
is not specified in these operating instructions, will be considered as improper
use. The customer is solely responsible for material damage and injury of persons
resulting from an improper use, Messrs. KERN & Sohn will not be liable under
any circumstance.
Messrs . KERN & Sohn cannot be held liable, if the suspended balance is
modified or used improperly and if damage is resulting from such use.
Inspect and service suspended balance and load suspension device regularly
(see chap. 9.2).
Log the test result and keep it in the logbook.
3.2 Organizational measures
Only trained and instructed staff may operate the balance.
Make sure that the operating instructions are kept nearby the operation site of the
suspended balance.
Assembly, commissioning and maintenance should only be carried out by trained
specialists.
Weight-bearing components must not be replaced
3.3 Environmental conditions
Never operate suspended balance in spaces exposed to explosion hazards. The
serial version is not explosion protected.
Operate the suspended balance only under environmental conditions as specified
in these operating instructions (especially in chapter 1 „Technical data“).
Do not expose the suspended balance to strong humidity. Non-permitted
condensation (condensation of air humidity on the appliance) may occur if a cold
appliance is taken to a considerably warmer environment. In this case,
acclimatize the disconnected appliance for ca. 2 hours at room temperature.
Do not use suspended balance in environments exposed to corrosion hazards.
Protect the suspended balance against high humidity, vapours and dust.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. Change location or
remove source of interference.

HDB-BA-e-1730 11
3.4 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.
3.5 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 suspended on the load receptor only vertically, manually,
carefully and without jerks. As soon as a stable weighing value is reached the
weighing value can be read.
Use the suspended balance only for lifting and weighing of freely movable loads.
Danger of injury due to improper use. Not allowed are e.g.:
-Exceeding the allowed nominal load of crane, suspended balance or any
type of load attachment devices
-Conveying persons,
-Pulling loads over an inclined surface,
-Tearing-off, pulling or towing loads.
Modifications or reconstructions of the suspended balance or of the crane are not
allowed.
3.6 Improper Use
Do not use 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“. (Example: Slowly draining fluids from a
container suspended on the balance.) Do not leave permanent load suspended on
the balance. This may damage the measuring system as well as safety-relevant
parts.
Make sure that never persons or objects are under the load which could be
injuried or damaged!
The balance is not suitable for weighing persons!
The balance does not correspond to the law of medical products (MPG).
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.

12 HDB-BA-e-1730
3.7 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
3.8 Safe working
Do not stand under swinging loads, see chap. 6.1.
Position the crane in a way that the load is lifted vertically.
When working with the crane and suspended balance wear personal safety
equipment (helmet, safety shoes etc.).
3.9 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.
3.10 Testing upon acceptance
Inspect packaging immediately upon receipt and inspect device when unpacking, see
chap. 5.1. in the event of any evident damage.
3.11 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1).
During this warming up time the balance must be connected to the power supply
(mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
For checking original dimensions, s. chap. 5.3
3.12 Shutdown and storage
Switch off suspended balance and remove batteries
Do not store suspended balance outdoors.

5.4 Battery operation
Illustration example HDB-N
Push out the battery cover on the balance backside. Insert batteries (2 x AAA 1.5V).
Reinsert the battery cover. If the batteries are empty, in the balance display appears
“LO”. Press ON/OFF-button and replace the batteries immediately. In order to save
the battery, the balance switches automatically off after 4 minutes without weighing
Deactivate this Auto-OFF function as follows:
When the balance is switched off, press the HOLD-button and keep it pressed
Do not release the HOLD-button. Press also the ON/OFF/TARE-button and keep
it pressed
Keep the ON/OFF/TARE-button pressed, however release the HOLD-button
