4 Basic Information (General)

4.1Proper 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 “nonautomatic“- 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.

4.2Improper Use

Do not use balance for dynamic addonweighing 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 Thisplate. 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 avoidedBalance. 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 modifiedThis. 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.

4.3Warranty

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

4.4Monitoring 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 regularlyThe . responsible user must define a suitable interval as well as type and scope of this test. Information is available on KERN’s home pagewww(.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

5.1Pay 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.

5.2Personnel training

The appliance may only be operated and maintained by trained personnel.

6 Transportation & Storage

6.1Testing 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

6.2Packaging / 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

7.1Installation 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.

7.2Unpacking and checking

Open package, take out the appliance and accessoriesVerify. 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

7.3Mains 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.

7.3.1 Turning On the Power

Supply power to balance via mains adapter. The display lights up and the balance carries out a selftest.

In the ABJ models an automatic adjustment takes place.

The selftest is completed when „OFF“ appears on the display.

7.4Initial 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.

7.5Connection 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

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.

8.1Automatic 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

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.

To prevent a start-up of adjustment during a measuring process, actuate the

ON/OFF button as soon as „PLS.CAL“ is displayed. The gram display flashes again for two minutes, followed by „PLS.CAL“.

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.
