Frequently Asked Questions - FXN 10K-3N Kern

How to adjust the Kern FXN 10K-3N scale?

Adjustment is necessary after a change of location or temperature fluctuations. Procedure: turn off the scale, move the adjustment switch under the base, turn it on, select option 02 CAL in the menu, follow the on-screen instructions to enter the mass of the adjustment weight (recommended: 15 kg), place the weight and confirm. After the beep, remove the weight and press a key to finish.

What does the error message E1 mean?

E1 indicates that the zero adjustment range is exceeded. This usually occurs if the platform is too heavy or the scale is not at zero. Solution: completely unload the platform and press the ON→0← key to reset zero. If the problem persists, check that the platform is correctly installed.

How to use the piece counting function?

Place a known number of pieces (e.g. 10) on the platform, then press the UNIT key to switch to counting mode. The scale calculates the unit weight and displays the number of pieces. To optimize the reference, add at least 5 additional pieces automatically. The function is only active if the total weight exceeds 20d (100 g for this model).

How to clean the scale?

Remove the batteries before cleaning. Use a slightly damp cloth with mild soapy water. Avoid solvents and ensure no liquid enters the device. Powder residues can be removed with a brush or vacuum cleaner. Wipe up spills immediately.

What to do if the scale displays an unstable value?

Possible causes: drafts, table vibrations, platform contact with an object, electromagnetic fields (cell phones, radios) or static charge. Try changing the scale location, eliminate sources of interference and ensure the scale is level (bubble centered).

How to change the batteries?

Open the battery compartment located under the scale. Turn both levers 90° to the left, remove the cover, replace the 4 used batteries with new type D (1.5 V) batteries. Close the cover and turn the levers 90° to the right. Ensure not to pinch the cables.

How to activate the Hold function?

In weighing mode, press BG/NET and ON→0← simultaneously. Navigate the menu to FnC 06, then select the desired Hold mode: 1 for Peak-Hold (max value), 2 for Hold 1 (stable value retained until key press), 3 for Hold 2 (automatic return to zero after unloading). Confirm and restart the scale.

What are the recommended adjustment weights?

The recommended adjustment weight for the FXN 10K-3N is 15 kg class M1. Use a weight with accuracy at least equal to readability (5 g). You can purchase test weights on the Kern website (www.kern-sohn.com).

How to reset the scale to factory settings?

Turn on the scale, then in weighing mode press BG/NET and ON→0← simultaneously. The display shows 01 FnC. Press TARE, then navigate to FnC 04. Confirm with TARE, the display shows 'rEturn'. Press TARE again, then turn off and on the scale. All parameters return to default values.

Can the scale be used for commercial use?

Yes, if it has a CE type approval certificate and current verification. The FXN 10K-3N models... (depending on variant) are suitable for commercial use in countries where verification is mandatory. Observe legal verification intervals (e.g., every 2 years in Germany). Do not break the verification seals.

3 Basic Information (General)

3.1 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.

3.2 Improper Use

Do not use balance for dynamic weighing. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation”. (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.

3.3 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

3.4 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. The test weights and balances can be quickly and cheaply calibrated in the KERN calibration laboratory accredited by DKD (Deutsche Kalibrierdienst) (with reference to the national standard).

4 Basic Safety Precautions

4.1 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.

4.2 Personnel training

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

5 Transport and storage

5.1 Testing upon acceptance

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

5.2 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.

6 Unpacking, Setup and Commissioning

6.1 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 scales on a stable, even 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 appliance for ca. 2 hours at room temperature.
• Avoid static charge of goods to be weighed or weighing container.

Major display deviations (incorrect weighing results) may be experienced should electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change location or remove source of interference.

6.2 Unpacking and placing

Carefully remove the balance from the packaging, remove plastic cover and setup balance at the intended workstation.

→ Move both levers 90° to the right

Ensure that the cables are not zed.

6.4 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).

For this warm-up period the scale must be connected to the power supply (batteries).

The accuracy of the balance depends on the local acceleration of gravity.

Strictly observe hints in chapter "Adjustment".

7 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 (unless the balance has been pre-adjusted in the target location).

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.

7.1 Adjusting

Carry out adjustment as close as possible to the maximum load of the scales)see chap. 1 „Technical data“). The accuracy of the adjustment weight must correspond approximately to or, if possible, be better than, the readability d of the balance.

Info about test weights can be found on the Internet at: http://www.kern-sohn.com

Procedure when adjusting:

Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization.

7.1.1 Adjustment

Operation

⇒ Turn off the balance and set the adjustment switch located on the bottom.⇒ Start the balance by pressingON→0←.⇒ PressBGNETandON→0←at the same time in weighing mode.⇒ The 01 FnC indication appears.

⇒ Select 02 EC by pressingON→0←.⇒ Confirm by pressingTARE, the device displays CAL 00, the first digit is blinking.⇒ Enter CAL 01 by pressingTARE, go to the next digit and increase it by 1 using theON→0←key.⇒ Confirm by pressingTARE, the device displays the value of adjustment weight, e.g. „015.0000 kg“.

⇒ Change the value by pressingTARE and ON→0←, and confirm by pressingTARE; or⇒ Apply the displayed value and confirm by pressingTARE.⇒ For a while, the device will display CENTER. During that time, the balance determines the zero point.⇒ Then it will display a blinking value of adjustment weight, as previously selected.⇒ Place the appropriate adjustment weight and confirm by pressingTARE.⇒ You will hear a sound signal, and the indication will start blinking.⇒ Remove the adjustment weight and press any key to complete the adjustment.⇒ The device will display the CAL 01 indication. Enter CAL 00 and confirm by pressingTARE⇒ The balance will display the 02 CAL indication.⇒ Swith over the adjustment switch.⇒ Restart the balance. It will display the zero value. The balance is now in the weighing mode.

In case of any adjustment error or using an incorrect adjustment weight, the balance will display an error message. Repeat the adjustment.

7.1.2 Verification

General information:

Pursuant to Directive 2009/23/EC, balances must be verified if used in the following manners (scope specified by law):

a) for trade, if the product price is determined by weighing;
b) for production of medicines in pahrmacies, and for analyses conducted at medical and pharmaceutical laboratories;
c) for official purposes;
d) for production of ready-made packagings.

In case of doubts, refer to the local Measurement Authority.

Guidelines for verification:

Balances marked in the technical specifications as suitable for verification have type-approval certificates applicable in the European Union. If the balance is to be used in one of the above-defined areas requiring verification, it must be verified and such verification must be renewed on a regular basis. The balance shall be re-verified in accordance with the national regulations. In Germany, the validity period of balance verification is usually 2 years. You must comply with the legal provisions applicable in the country of use!

Verification of a balance without seals is invalid.

For balances with type-approval certificates, the seals indicate that the balance may be opened and maintained only by trained and authorised professional personnel. Destruction oft he seals causes invalidity oft he verification. You must comply with the national laws and regulations. In Germany, re-verification is required.

	The weight of the weighing container will be displayed as a minus number (=gross weight) after removing the weighing container.The tare weight is saved until it is deleted. Remove the load from the balance and press The zero display appears and the triangle ▼ above the net weight symbol NET vanishes.
	Gross weight:⇒ Press as long as the weighing container and the object to be weighed are on the weighing plate.⇒ Remove the object to be weighed as well as the weighing container.The gross weight is displayed as a negative value.

8.3 Parts counting

Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts, the so-called reference quantity. Counting is then carried out on the basis of the calculated average piece weight.As a rule:The higher the reference quantity the higher the counting exactness.

	→ Remove reference weight. The balance is from now in parts counting mode counting all units on the weighing plate.
	→ Back to Weighing mode by pressing the UNIT button repeatedly.

i

By switching the scale off and then on again the scale starts in the parts counting mode. The current reference weight remains stored until the reference is set again or the power supply is interrupted.

The counting function is not active, if the weight is under 20d or if below the minimum piece weight (< 0.2 D) is reached.

Automatic reference optimization

In order to improve the counting exactness, the reference can be optimised by adding more pieces. At every reference optimisation, the reference weight is calculated anew. As the additional pieces increase the base for the calculation, the reference also becomes more exact.

While the automatic reference optimization function is available the number of placed parts are 5 pieces more than the reference and less than double the reference, then balance will automatically re-sample the unit weight.

Indicator [▼] atop the symbol shows:

Number of parts placed on balance too small

Piece below minimum weight of piece
