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.

ABS-N_ABJ-NM-BA-e-1312 15

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.

 Level balance with foot screws until the air bubble of the water balance is in the

prescribed circle.

 Check levelling regularly

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

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

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.

The easy setting display flashes for a short time. Inputs are only possible

Exists the possibility to tune the stability of the display and the degree of reaction of
the balance to the requirements of certain applications or the environmental
conditions.
Most measurements can be carried out using default settings, that is, standard
mode. In standard weighing mode, stability and reaction have the same priority. For
certain applications such as e.g. dosage do use the dosing mode (pouring mode). In
dosing mode the reaction degree has the higher priority.
Beside the selection standard / dosing mode the stability of the display and the
reaction degree of the balance can additionally adapted in the menu.
Please note that data processing for greater stability generally slows the response
and processing for higher response reduces stability.

With parts counting you can either count parts into a container or remove parts from
a container. To count a greater number of parts the average weight per part has to
be determined with a small quantity (reference quantity). The larger the reference
quantity, the higher the counting exactness. High reference must be selected for
small parts or parts with considerably different sizes.

external devices. This data exchange is asynchronous using ASCII - Code.
The following conditions must be met to provide successful communication between
the weighing balance and the printer.

• Use a suitable cable to connect the weighing balance to the interface of the
printer/PC.

Faultless operation requires an adequate KERN interface cable (optional).

• Communication parameters (baud rate, bits and parity) of balance and printer
