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 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.

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 and damage caused 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 Transport 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.

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:

• 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.

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.

7.2 Unpacking

Carefully remove the weighing balance from the packaging and install it at the designated work place.

7.2.1 Placing

The balance must be installed in a way that the weighing plate is exactly in horizontal position.

7.2.2 Levelling (FOB and FOB-LM models only)

Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.

Two circular diagrams with concentric rings and intersecting lines, no text or symbols present

i

Check levelling regularly.

7.2.3 Scope of delivery

Serial accessories:

• Balance
- Weighing pan
- Mains adapter (standard, FOB models only)
- Battery (all models except FOB models)
- Rechargeable battery (standard, FOB models only)
- Protective cover
- Operating manual

- Mains adapter (option KERN FOB-A01, all models except models FOB)

7.3 Mains connection

The balance may be operated via the optional 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.

→ Unlock weighing pan in the direction of the arrow

→ Remove or replace the protection hood

Models FOB-LM:

Fasten the weighing plate support on the balance with the help of the three delivered screws.After that attach the weighing plate.

7.4 Battery operation

Remove battery cover at the lower side of the housing. Insert Battery, see. Chap. 1 "Technical Data".

Put battery cover back in place and tighten it.

Illustration example:

FOB-NS

Back view of a rectangular electronic device with mounting holes and a central component (no text or symbols visible)

FOB-NL, FOB-LM

Interior view of a rectangular electronic device with mounting holes and a central circular component (no text or symbols visible)

When you tighten the battery cover, make sure that not too much pressure is put on the weighing plate. The load cell may be damaged.

In the menu you can activate the AUTO-OFF function (see chap. 10.5.2 "Automatic switch-off function"). According to the selected settings, the balance switches automatically off in order to spare the battery.

The empty battery is indicated on the display by „LobAt“. Press ON/OFF-key and replace the battery/ies immediately.

If the balance is not used for a longer time, take out the battery/ies and store it/them separately. Leaking battery liquid could damage the balance.

7.5 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 or battery).

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

Strictly observe hints in chapter Adjustment.

7.6 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.

The adjustment should be made with the recommended adjustment weights (see chap. 1 "Technical data").

Procedure when adjusting:

Observe stable environmental conditions.

A warming up time (see chapter 1; Technical Data) is required for stabilization.

Ensure that there are no objects on the weighing plate.

8 Verification (FOB-LM models only)

General introduction:

According to EU directive 2014/31/EU 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!

i

Verification of the balance is invalid without the seal.

The seal marks attached on balances with type approval 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 reverification will be necessary.

	Should the balance not display exactly "0" despite unloaded weighing pan, press the TARE key. The balance returns to „0“
(example)	Place weighed items on balance.Wait until the stability display appears.Read weighing result.
	To turn off the balance, press the ON/OFF-key shortly.

9.2 Taring

The dead weight of any weighing container may be tared away by pressing a button, so that the following weighing procedures show the net weight of the goods to be weighed.

Balance display Operation
(example)	Deposit weighing container.The weight of the container is displayed.
	Press theTAREbutton, the zero display disappears.The weight of the container is now internally saved.
(Example FOB-NS)(Example FOB-NL)	Place weighed items in the weighing container.The net weight of the weighed items is displayed.For L models, a triangle appears below the NET symbol.

9.3 Switch-over weighing unit

According to the requirements the balance can be switched over into different units. These are set in the menu.

In the weighing mode, press the UNIT key to toggle to the selected weighing units.

i	The available weighing units depend on the model and verification of the balance, see chap.1 "Technical data".When switching- on the balance, the unit in which the balance has been switched off, will be displayed.

9.4 Hold function (FOB, FOB-NL/-LM/ models only))

The balance has an integrated standstill function (mean value calculation).

With this it is possible to weigh unstable samples to be weighed exactly.

There are 2 possibilities:

Balance display	Operation
	Turn on balance by pressing the ON/OFF key.The balance will carry out a self-test.Wait for „0“ display
	Put the weighed item in place and press the HOLD key; "HOLD" will appear and a small triangle flashes. During this time, an average value is recorded.
(example)	The triangle will stop flashing, the stability display appears and the weight value obtained is displayed.
	By pressing the HOLD button several times, the balance returns to weighing mode. The triangle disappears.

9.5 Display background illumination (FOB, FOB-NL/-LM/ models only)

The balance has the ability to turn the backlight of the display on or off.

⇒ Press the TARE key for approx. 3 sec.

9.6 Weighing with tolerance range (FOB, FOB-LM models only)

You can set an upper or lower limit when weighing with tolerance range and thus ensure that the weighed load remains exactly within the set limits.

During tolerance tests such as dosing, portioning and sorting the unit will indicate exceeded or undershot limits by emitting an optical or acoustic signal.

Displayed triangle next to	Weight of the weighed item	Acoustic signal	Optical signal / background illumination of the display
√	Target weight within tolerance range	2 short beeps
-	Target weight below lower tolerance limit	no beep
+	Target weight above upper tolerance limitIfis displayed, the maximum load of the balance is exceeded.	perpetual tone

Call function:

- Press and hold the HOLD key for three seconds in the weighing mode. The tolerance weighing mode is displayed. The display for entering the lower limit value appears, the first digit flashes. The lower tolerance mark is displayed.

Set limit values:

- To change the flashing digit, press the TARE button repeatedly until the desired value is displayed. Select the next digit with the UNIT key and set the value with the TARE key.

- Repeat process for each digit.

- Confirm entry with the HOLD key. The display for entering the upper limit value appears, the first digit flashes. The upper tolerance mark is displayed. The display lights red.

- To change the flashing digit, press the TARE button repeatedly until the desired value is displayed. Select the next digit with the UNIT key and set the value with the TARE key. Repeat process for each digit.

- Finish the input with the HOLD-key, from here, you can determine whether the weighed item is within the two tolerance limits.

Tolerance weighing

→ Tare when using a weighing container.
⇒ Put on goods to be weighed, tolerance control is started. The visual and acoustic signals indicate whether the weighed item is within the two tolerance limits.

Load below specified tolerance	Load within specified tolerance	Load exceeds specified tolerance
The tolerance mark ▶next to "-" is displayed	The tolerance mark ▶next to "√" is displayed	The tolerance mark ▶next to "+" is displayed

Return to weighing mode:

12 Servicing, maintenance, disposal

12.1 Cleaning

Before cleaning, please disconnect the appliance from the operating voltage.

→ Clean the stainless-steel parts with a soft cloth soaked with a cleaning agent suitable for stainless steel.
For stainless steel parts do not use any cleaning agents which contain sodium hydroxide solution, acetic, hydrochloric, sulphuric or citric acid.
Do not use metal brushes or cleaning sponges of steel wool, as this causes superficial corrosion.

Spilled weighing goods must be removed immediately.

12.2 Servicing, maintenance

The appliance may only be opened by trained service technicians who are authorized by KERN.

Before opening, disconnect from power supply.

12.3 Disposal

Disposal of packaging and appliance must be carried out by operator according to valid national or regional law of the location where the appliance is used.

13 Instant help

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.

Help:

Fault Possible cause

The displayed weight does not glow.

• The balance is not switched on.
• The mains supply connection has been interrupted (mains cable not plugged in/faulty).
  • Power supply interrupted.
• (Rechargeable) batteries are inserted incorrectly or empty
• No (rechargeable) batteries inserted.

The displayed weight is permanently changing

• Draught/air movement
• Table/floor vibrations
• Weighing pan has contact with other objects.
• Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

The weighing result is obviously incorrect

• The display of the balance is not at zero
- Adjustment is no longer correct.
• Great fluctuations in temperature.
• Warm-up time was ignored.
- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

Should other error messages occur, switch balance off and then on again. If the error message remains inform manufacturer.
