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 plate. As soon as a stable weighing value is reached, the weighing value can be read.
3.2 Improper Use
- Our balances are non-automatic balances and not provided for use in dynamic weighing processes. However, the balances can also be used for dynamic weighing processes after verifying their individual operative range, and here especially the accuracy requirements of the application.
- 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 the 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 beyond 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
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.
On the installation site observe the following:
- 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.
- Do not operate in areas with hazard of explosive material or in potentially explosive atmospheres due to materials such as gasses, steams, mists or dusts.
- Keep away chemicals (such as liquids or gasses), which could attack and damage the balance inside or from outside.
- In the event of the occurrence of electromagnetic fields, static charges (e.g., when weighing / counting plastic parts) and unstable power supply, large display deviations (incorrect weighing results, as well as damage to the scale) are possible. 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.

- Hexagonal socket wrench
6.3 Rechargeable battery operation (optional)
The rechargeable battery is charged via the delivered power supply.
The operating time of the rechargeable battery with background illumination is 30h, without that it is 50 hrs. Charging time until complete recharging 12h.
In the menu you can activate the AUTO-OFF function [time off], see chap. 9.2.
According to menu settings, the balance switches automatically off in order to spare the battery.
Insert rechargeable battery:

Remove any adherent moisture from the balance
Rotate both levers (1) 90 degrees to the left

Remove battery compartment cover and the foam pieces

Connecting the rechargeable battery

Watch the colours:
Red on red!
Black on black!

Insert the rechargeable battery in a manner that it cannot slip (fasten with a rubber foam mat)

Ensure that the cables are not squeezed.

Close the rechargeable battery cover
Rotate both levers (1) 90 degrees to the right
If in the display the triangle appears above the capacity display, the rechargeable battery is nearly exhausted. Connect power pack, the rechargeable battery is loaded.

Avoid excess pressure on the balance in order to avoid damaging it, particularly as it is supported by the weighing plate.
6.3.1 Mains connection during rechargeable battery operation

During the rechargeable battery operation ensure that the mains connection is covered with a rubber cap. Only by this the type of protection IP65 is ensured.

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.
6.5 Type of protection IP65
The KERN WTB meets the requirements for IP65 protection type.
Suitable for a short-time contact with liquids. For cleaning use damp cloth. Dust-tight.
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 (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.
7.1 Adjustment
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. Information about test weights you will find in the internet under http://www.kernsohn.com
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization.

7.2 Verification
General introduction:
According to EU directive 2014/31EU 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.
7.2.1 Adjustment switch and seals
After a verification the balance is sealed at the indicated positions.
Position of the official seals:

- Fastening calibration wire
- Fixing calibration wire
- Pin insert
- Self-destructing sealing mark
- Adjustment switch
