3 Basic Information (General)
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 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“ 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 maxim um 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. T he 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. In KERN’s accredited DKD calibration laboratory test weights and balances may
be calibrated (return to the national standard) fast and at moderate cost.
FKB_A-BA-e-1513 9
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.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transportation & Storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts, e.g. weighing plate,
mains adapter etc., to prevent slipping and damage.
6 Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
• Place the balance on a firm, level surface;
• Avoid extreme heat as well as temperature fluctuation caused by installing next to
a radiator or in the direct sunlight;
• Protect the balance against direct draughts due to open windows and doors;
• Avoid jarring during weighing;
• Protect the balance against high humidity, vapors and dust;
• Do not expose the device to extreme dampness for longer periods of time. 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.
• Avoid static charge of goods to be weighed and weighing container.
FKB_A-BA-e-1513 10
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.
6.2 Unpacking/erection
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
The balance must be installed in a way that the weighing plate is exactly in horizontal
position.
• Place the balance on a horizontal and solid base.
• Remove the transport security on the 4-point support.
• Pull off the protection foil from the weighing plate if existing.
• Attach the weighing plate.
Scope of delivery / serial accessories
• Balance
• Weighing plate
• Transit Securing
• Mains power supply
• Protective cover
• Operating Manual
6.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage.
Only use original KERN mains adapters. Using other makes requires consent by
KERN.
FKB_A-BA-e-1513 11
6.4 Operation using a (rechargea bl e) battery (optional)
„AF on“:
In order to save the battery, the balance switches automatically
„AF off“:
Switch-off function deactivated.
Lift-off the battery cover on the lower side of the balance. Connect 9 V compound
battery.
Replace the battery compartment cover.
For battery operation the balance has an automatic switch-off function which can be
activated or deactivated in the menu (chapter 9).
In weighing mode keep the PRINT-key pressed until [Unit] appears.
Press MODE key repeatedly until „AF“ appears.
Use the SET key, to confirm.
Use the MODE key to choose between the two following settings:
off after 3 minutes without weighing.
Use the SET key to confirm. The balance returns to weighing mode.
If the batteries are run down, "LO" appears in the display. Press ON/OFF-key and
replace the batteries immediately.
If the balance is not used for a longer time, take out the batteries and store them
separately. Leaking battery liquid could dam age the balance.
If there exists an optional rechargeable battery, it has to be connected in the battery
compartment via a separate plug-in socket. Now the mains adapter delivered with
the rechargeable battery m ust be applied.
6.5 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.
FKB_A-BA-e-1513 12
6.6 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.
6.7 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
6.8 Adjustment
The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data"). Adjustment is also possible with the weights of other
nominal values (see table 1), but not the optimum for measuring technique.
Procedure when a djusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
Turn on balance by pressing the ON/OFF key.
Press the MODE key and keep it pressed, in the display appears shortly
„CAL“. After that the exact size appears flashing in the display (see
chapter.9.3) of the adjustment weight.
Now set the adjusting weight in the centre of the weighing plate.
Press the SET key. Short time later there appears „CAL F“, then the
automatic return to the weighing mode. In the display there appears the
value of the adjustment weight.
An error during adjustment or the use of an incorrect adjusting weight will
result in an error message „CAL E“. Repeat adjustment.
Keep the adjustment close to the balance. Daily control of the weighing exactness is
recommended for quality-relevant applications.
FKB_A-BA-e-1513 13
6.9 Underfloor weighing
▬ Always ensure that all suspended objects are stable enough to
might be damaged underneath the load.
After completing the underfloor weighing the opening on the bottom of
the balance must always be closed (dust protection).
Objects unsuitable for placing on the weighing scale due to size or shape may be
weighed with the help of the flush-mounted platform.
Proceed as follows:
• Switch off the balance
• Open closing cover at the balance bottom.
• Suspend hook for underfloor weighing carefully and completely.
• Place weighing balance over an opening.
• Attach load to hook and carry out weighing procedure.
Fig. 1: Setup of balance for underfloor weighing

10.4 Output on bar code pr i nter
The data transfer mode has to be set on „BA Pr “ (chapter 9.4).
As bar code printer the Zebra printer model LP2824 is provided.
Take into account that the output format of the balance is fixedly defined and cannot
be changed.
The printer format is stored in the printer, i.e. in case of a failure the printer cannot be
changed with a new one from factory, previously it is necessary that K ERN installs
the respective software.
The Zebra printer and the balance must be connected to the delivered interface
cable when they are switched off.
After switching-on both appliances, and after reaching the status ready-for-operation,
a label will be printed out when pressing the PRINT button.
