4 Basic Information (General)
4.1 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.
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 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.
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 use
• 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
12 ABS-N_ABJ-NM-BA -e-1312
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 Transportation & Storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
ABS-N_ABJ-NM-BA-e-1312 13
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.
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.

7 Unpacking, Setup and Commissioning
7.1 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:
• Operate the device only indoors.
• 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, vapours 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 or weighing container.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.
7.2 Unpacking and checking
Open package, take out the appliance and accessories. Verify that there has been
no damage and that all packing items are present.

7.2.2 Placing
Attach circular screen, carrier of weighing plate and weighing plate in order.
Level balance with foot screws until the air bubble of the water balance is in the
prescribed circle.
Check levelling regularly
18 ABS-N_ABJ-NM-BA -e-1312
7.3 Mains connection
Supply power to balance via mains adapter. The display lights up and the
The selftest is completed when „OFF“ appears on the display.
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.
7.3.1 Turning On the Powe r
balance carries out a selftest.
In the ABJ models an automatic adjustment takes place.
7.4 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chpt. 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.
7.5 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.
ABS-N_ABJ-NM-BA-e-1312 19
8 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.
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization. Ensure that there are no objects on the weighing plate.
8.1 Automatic adjustment by PSC (Perfect Self Calibration), only models ABJ
The default setting for balances of the series ABJ prompts automatic adjustment via
the PSC function (cannot be switched off).
The moment a change in temperature is detected this function uses the internal tare
weight to carry out fully-automatic adjustment with the help of a temperature sensor.
Adjustment in weighing mode is carried out automatically under the following
conditions:
(1) When there is a change in the surrounding temperature (∆t 2°C)
(2) When about four hours has passed since the previous calibration.
(3) When the balance is switched from standby status to weighing mode
and condition (1) or (2) has been met.
If one of the above conditions was met in weighing mode, the weight symbol
flashes for about two minutes in order to notify the pending adjustment;
20 ABS-N_ABJ-NM-BA -e-1312
Case 1: The load on the weighing plate is near zero.
The weight symbol flashes for approx. two minutes, followed by „PSC.RUN“.
After that the internal adjustment is started automatically. In order to ensure proper
PSC operation, prevent vibrations and air flow.
As soon as the display in grams reappears after completing adjustment via PSC,
the balance returns to weighing mode.
ABS-N_ABJ-NM-BA-e-1312 21
To prevent a start-up of adjustment during a measuring process, actuate the
again for two minutes, followed by „PLS.CAL“.
Case 2: Weighing plate loaded
The gram display flashes for two minutes, followed by „PLS.CAL“.
Unload weighing plate. The gram display flashes again for 2 minutes; after that the
internal adjustment is started automatically. In order to ensure proper PSC
operation, prevent vibrations and air flow.
As soon as the display in grams reappears after completing adjustment via PSC,
the balance returns to weighing mode.

9 Verification
General introduction:
According to EU directive 90/384/EEC or 2009/23EG balances must be officially
verified if they are used as follows (legally controlled area):
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the
medical and pharmaceutical laboratory.
c) For official purposes
d) For manufacturing final packages
In cases of doubt, please contact your local trade in standard.
Verification notes:
An EU type approval exists for balances described in their technical data as
verifiable. If a balance is used where obligation to verify exists as described above, it
must be verified and re-verified at regular intervals.
Re-verification of a balance is carried out according to the respective national
regulations. The validity for verification of balances in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
Verification of the balance is invalid without the seal.
The seal marks attached on verified balances point out that the balance may
only be opened and serviced by trained and authorised specialist staff. If the
seal mark is destroyed, verification looses its validity. Please observe all
national laws and legal regulations. In Germany a re-verification will be
necessary.
