Frequently Asked Questions - ABJ 220-4NM Kern

How do I adjust the Kern ABJ 220-4NM balance?

Adjustment can be performed automatically via the PSC (Perfect Self Calibration) function using an internal weight. For manual adjustment with an external weight, press the CAL key for 3 seconds, select E.CAL if necessary, then follow the on-screen instructions. Ensure the pan is empty and environmental conditions are stable.

How do I use the piece counting mode?

Activate PCS mode in the application functions menu. Place an empty container, tare, then press MENU twice to select the reference piece quantity (5, 10, 20, 50 or 100). Add the corresponding number of pieces and confirm with TARE. The balance calculates the unit weight and displays the piece count for any subsequent load.

What does the error message <b>ERR C</b> mean and how to fix it?

ERR C indicates a large zero point offset during adjustment. Press ON/OFF to return to weighing mode, then restart the adjustment. Verify that no object is on the pan and that the pan is correctly installed.

How do I change the weighing units?

In weighing mode, press UNIT to cycle through activated units (g, mg, ct). To activate or deactivate units, press and hold UNIT for 3 seconds, navigate with the arrows, press TARE to enable/disable, then exit the menu with ON/OFF.

How do I use the taring function?

Place the empty container on the pan, wait for the stability indicator to light up, then press TARE. The container's weight is stored and the display returns to zero. You can then weigh the net contents. To clear the tare, unload the pan and press TARE again.

How do I connect a printer to the balance?

The balance has a data interface (RS-232). Before connecting the printer, turn off the balance. Use only KERN-recommended peripherals. Set the communication parameters in the Data Output menu (baud rate, parity, etc.) according to your printer. Preset modes MODE 1 to MODE 5 are available for common printers.

How do I lock the menu to prevent accidental changes?

Put the balance in Stand-by mode (displays OFF or READY). Press MENU for 3 seconds, enter the password (default 9999) and confirm with TARE. The lock symbol appears, indicating the menu is locked. To unlock, repeat the process entering the same password.

What is the recommended warm-up time before precise weighing?

The warm-up time for the Kern ABJ 220-4NM balance is 8 hours after power-on. This allows the balance to reach the thermal stability required for accurate results. For routine weighings, a shorter warm-up may suffice, but for high-precision measurements, respect the 8 hours.

How do I clean the balance without damaging it?

Before cleaning, disconnect the balance. Use a damp cloth with mild detergent (soap) to clean the housing and display. The weighing pan can be removed and washed with water, then dried before reassembly. The glass doors can be dismantled (remove the plastic handle by turning) and cleaned with glass cleaner. Avoid any liquid entering the device.

Why does the display fluctuate and how to stabilize the balance?

Fluctuations can be caused by drafts, vibrations, electromagnetic fields, or incorrect leveling. Ensure the balance is level (bubble centered) and placed on a stable surface. Close the draft shield doors. You can also adjust stability via the Easy Setting screen (briefly press MENU) by increasing stability priority with the UNIT or PRINT key.

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

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.

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.

    style A fill:#f9f,stroke:#333
    style C fill:#f9f,stroke:#333

→ Check levelling regularly

7.3 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.

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.

7.4 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.

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;

Case 1: The load on the weighing plate is near zero.

The weight symbol PSC 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.

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“.

8.2 Menu settings „I.CAL“ / „E.CAL“

⇒ To invoke the adjustment function in weighing mode, press CAL for 3 sec.

Acknowledge using PRINT, the current setting is displayed.
⇒ Select the desired adjustment using the navigation keys (↓ ↑)

I.CAL: Adjustment with internal weight (see chpt. 8.1)

E.CAL: Adjustment with external weight (see chpt. 8.2)

→ Confirm with TARE

⇒ Press ON/OFF repeatedly or 3 sec., the balance will return into weighing mode

i The saved adjustment (I.CAL or E.CAL) can now directly be invoked via the CAL button.

8.2.1 Adjustment with internal weight (KERN ABJ)

With the internal adjustment weight, the weighing accuracy can be checked and re-adjusted at any time.

• Condition: Menu setting „I.CAL“.
- When an optional printer is connected and the GLP function activated, while starting the adjustment log „WAIT“ will be displayed. After the printout the adjustment will be continued automatically.
- Adjustment may be interrupted with ON/OFF, „ABORT“ is displayed.

⇒ Press the CAL-button and adjustment will take place automatically.

The indicator will be shown.

⇒ After successful adjustment the balance automatically returns to weighing mode.

In case of an adjustment error (e.g. objects on the weighing plate) the display will show an error message, repeat adjustment.

When an optional printer is connected and the GLP function is connected, the adjustment log will be edited, see chpt. 8.3.

8.2.2 Adjustment with external weight (KERN ABS)

• Condition: Menu setting „E.CAL“.

- The weight to be used depends on the capacity of the scale. Carry out adjustment as near as possible to the balance's maximum weight (recommended adjustment weight see chpt. 1). Weights of different nominal values or tolerance classes may be used for adjustment but are not optimal for technical measuring. The accuracy of the adjustment weight must correspond approximately to or, if possible, be better than, the readability of the balance.

Minimum weight „Adjustment weight“:

ABS 80-4N / ABS 120-4N : 50 g

ABS 220-4N / ABS 320-4N:100 g

Information about test weights you will find in the internet under:

http://www.kern-sohn.com

- When an optional printer is connected and the GLP function activated, while starting the adjustment log „WAIT“ will be displayed. After the printout the adjustment process will be continued automatically.

- If during the adjustment process within 60 s no operation is carried out, „ERR C“ will be displayed. Press ON/OFF a restart.

In weighing mode press CAL. The weight value of the recommended adjustment weight (see chpt. 1) appears flashing. The indicator will be shown.

If the value shall be changed, press MENU, the active digit flashes.

Carry out the desired setting using navigation buttons (see chapter 3.1.1 „Numeric input“).

With flashing adjustment weight display, place the adjustment weight carefully on the center of the weighing plate within 60 s. Close wind screen doors completely.

→ Wait until the zero display flashes.

⇒ Take away the adjustment weight and close the wind screen doors. After successful adjustment the balance automatically returns to weighing mode. In case of an adjustment error (e.g. objects on the weighing plate) the display will show an error message, repeat adjustment.

When an optional printer is connected and the GLP function is connected, the adjustment log will be edited, see chpt. 8.3.

8.3 Adjustment log

This function enables automatic log issue after each adjustment. These logs may be issued by using an optional printer.

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.

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.

13.1 Stability and reaction settings via „Easy Setting display“ (without invoking menu)

☐ In weighing mode press MENU shortly. The easy setting display [R] flashes.
☐ When the display is flashing, set stability or reaction via UNIT or PRINT as described in the following.

15 Check weighing and target mode (check and target weighing)

• The check weighing or target mode can be applied for the application functions (see chpt. 14).
• The balance starts in the mode, in which it has been switched off.

15.1 Check weighing

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.

The indicators HI, OK or LO in the display show, where the weighed goods are located within the tolerance range.

These indicators are only functioning in check weighing or in target mode, otherwise they cannot be seen.

The indicators provide the following information

Condition Grading Indicator
OVR.RNG < sample weight	Beyond tolerance limit	No indicator
HI.LIM < sample weight ≤ OVR.RNG	Upper tolerance limit	HI
LO.LIM ≤ sample weight ≤ HI.LM	Inside tolerance range	OK
UND.RG ≤ sample weight < LO.LIM	Lower tolerance limit	LO
Sample weight < UND.RG	Beyond tolerance limit	No indicator

LO.LIM ≤ sample weight ≤ HI.LM(sample weight 6.0000g - 7.000g)		OK is displayed
HI.LIM < sample weight ≤ OVR.RNG(sample weight 7.0001g - 8.0000g)		HI is displayed
Sample weight >OVR.RNG(sample weight >8.0000 g)		No indicator is displayed

15.2 Target mode

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.

The indicators HI, OK or LO advise, when the target value is reached.

These indicators are only functioning in check weighing or in target mode, otherwise they cannot be seen.

The indicators provide the following information:

Condition Grading Indicator
Weight more than the nominal weight and above the upper tolerance	Great difference to target value	HI flashes slowly
	Small difference to target value	HI flashes fast
Weight within tolerance (target value ± tolerance)	Target value accepted	OK

Possible causes of errors:

In case of an error in the program process, briefly turn off the balance and disconnect from power supply. The weighing process must then be restarted from the beginning.

Fault Possible cause

The displayed weight does not appear

The displayed weight is permanently changing

The weighing result is obviously incorrect

The desired weighing unit cannot be called by UNIT key.

Automatic adjustment carried out frequently.

No data transfer between printer and balance.

The menu settings cannot be changed.

- The balance is not switched on.

- The mains supply connection has been interrupted (mains cable not plugged in/faulty).

• Power supply interrupted.

- Draught/air movement

- Glass doors not closed

- Table/floor vibrations

- Weighing plate has contact with other objects.

- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

• The display of the balance is not at zero

- Adjustment is no longer correct.

• The balance is on an uneven surface.

• Great fluctuations in temperature.

- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

• Unit was not activated beforehand.

- Severe temperature variations in the room or the instrument

- Communication settings are wrong.
