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 pan. 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 pan. 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 uses

• 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

16 ABP-BA-e-1810

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 Opera tion Manual

 Carefully read this operation manual before setup and

commissioning, even if you are already familiar with KERN balances.

 All language versions contain a non-binding translation.

The original German is binding.

5.2 Personnel training

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

6 T ransport and storage

6.1 Testing upon acceptance

When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.

ABP-BA-e-1810 17

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.

Illustration example models d = 0.0001 g

 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.

 Put network adapter and accessories in the small box

 Lift scale with both hands

ABP-BA-e-1810 19

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:

• 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 weighed items 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

Remove device and accessories carefully from packaging, remove packaging material and place device at the planned work place. Check if that there has been no damage and that all packing items are present.

4. Levelling

 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

Select a country-specific power plug and insert it in the mains adapter.

Check, whether the voltage acceptance on the scales is set correctly. Do not connect the scales to the power mains unless the information on

the scales (sticker) matches the local mains voltage.

Only use KERN original mains adapter. Using other makes requires

consent by KERN.

Important:

 Before starting your weighing balance, check the mains cable for

damage.

 Ensure that the power unit does not come into contact with liquids.  Ensure access to mains plug at all times.

ABP-BA-e-1810 25

7.3.1 Turning On the Power Models d = 0.0001 g Mode. d = 0.00001 g/0.0001 g

Supply power to balance via mains adapter. The display lights up and the balance carries out a selftest. Internal adjustment will be started automatically (See chap.8.3.2). The motor noise of the loading system for the internal adjustment weight will be audible.

You can cancel the adjustment by

pressing the ON/OFF key.

The selftest is completed when „OFF“ appears on the display. From that point onwards the weighing scale will be in standby mode. The weighing balance will remain switched on as long as it is connected to the power supply.

To turn the display on/off, press the

ON/OFF key.

When the log-in function is enabled, use the navigation keys to select the respective user and enter password, see chap. 12.7



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 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.

26 ABP-BA-e-1810

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.

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 pan.

• Avoid vibration and air flow.

• Always carry out adjustment with the standard weighing platform in place.

• To cancel internal adjustment, press the ON/OFF key.

•

When an optional printer is connected and the GLP function is connected,

the adjustment log will be edited, see chap. 8.4

8.1 Automatic adjustment via PSC function

Force-compensated scales react sensitively to changes in temperature. The higher the sensitivity of the scale, the more pronounced the effect. The temperature controlled PSC function enables the scale to automatically correct this effect.

PSC stands for Perfect Self Calibration and facilitates fully automatic internal scale

adjustment by means of an internal weight, based on time and/or temperature criteria. Adjustment in weighing mode is carried out automatically under the following conditions:

(1) If there is a change in ambient temperature (∆t 1°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.

ABP-BA-e-1810 27

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; During operation, the display will automatically change and the motor sound of the weight loading system is heard. In order to ensure proper PSC operation, prevent vibrations and air flow.



• The PSC function will be enabled throughout in verified models.

• Also, no measurements can be made during automatic adjustment.

• When the weight symbol

starts flashing while the weighing platform is

loaded the following message will appear



Unload weighing plate

• In order to prevent that adjustment is starting during a measuring sequence, press the ON/OFF key immediately when the following display appears. This will cancel the adjustment and you can proceed with the measuring sequence. Sometime later adjustment will be requested again by the flashing weight

symbol .

28 ABP-BA-e-1810

8.2 Time-controlled automatic adjustment

With the help of its internal adjusting weight and integrated clock the balance can be set to carry out automatic adjustment at set times (up to three times daily). This function is a very convenient function, when adjustment reports are desired to be made for regular adjustments, or when wishing span adjustments during break times to avoid interruption of measurement work.

The weight symbol blinks for about two minutes as notification of span calibration

before it begins. Automatic adjustment can be stopped by actuating the [ON/OFF]

key during this message.

Parameter setting:

Press and hold the CAL-key for approx. 3 sec. and the menu for <CAL key>

9 Verification

General introduction:

According to EU directive 2014/31/EC 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.

12.4 Settings for Stability and Response

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 may be carried out by using default settings. In standard weighing mode, stability and reaction have the same priority. For certain applications such as e.g. dosage do use the dosing 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 in general slowing down reaction times result in higher stability of the set data handling, while speeding up reaction times have an influence on the stability deterioration.

12.4.1 Stability and reaction settings via „Smart Setting display“ (without invoking menu)

14.1 Parts counting

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.

14.9 Control weighing and target weighing

This function is used to determine the matching of a weighing value to the specified control values. Control values can be exact target values (target weighing) or the limits set for the tolerance range (control weighing) within which the weighing value is to be kept.

14.9.1 Target weighing

This mode e.g. is used for weighing constant liquid quantities or for assessment of missing quantities or excess quantities.

The target value is the numeric value which corresponds to the nominal quantity of the used unit. Beside the target value a tolerance value is entered. This is a numerical value which is plus/minus over or under the acceptable target value. Reaching of target value is shown on the diagram. The tolerance marks

, or

indicate whether the weighed good is below, within or above the

specified tolerances.

14.10 Control weighing (Pass / Fail evaluation)

In many cases not the nominal value of the weighed goods is the decisive parameter, but the deviation from this nominal value. Such applications are for example the weight check of equivalent packages or the process check of parts in a fabrication process. By entering the upper and lower limit you can ensure that the weighed weighed good remains exactly within the set tolerance range at all time. If the values of limits are exceeded or not reached this will be indicated by the

displayed indicators
