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
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 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 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.
4.3 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

TFKB_B-BA-e-2210 13
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 staff.
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 wind screen, the weighing platform, power
unit etc. against shifting and damage.

14 TFKB_B-BA-e-2210
7 Unpacking, Installation 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 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
Remove device and accessories from packaging, remove packaging material and
install the device at the planned work place. Check if that there has been no damage
and that all items of delivery scope are present.
Scope of delivery / serial accessories:
•Balance, see chap. 3.1
•Mains adapter
•Operating instructions
•Protective hood
•Flush-mounted hook

TFKB_B-BA-e-2210 15
7.3 Assembling, Installation and Levelling
Remove the four transport securing devices above the supports of the weighing
platform
Install weighing plate and wind shield if necessary.
Ensure that the balance is installed in a level position.
Level balance with foot screws until the air bubble of the water balance is in the
prescribed circle.
Check levelling regularly
7.4 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 adapters. 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.
7.5 Battery operation (optional)
When the batteries are exhausted, in the display will appear <Lo Bat>.
Rotate the balance carefully in a way that the bottom of the balance is freely
accessible.
Open the battery compartment and exchange the batteries.
Ensure correct polarisation.
Close again the lid.
•To save the battery, in menu (see chap. 13.3.1.) the automatic switch-off
function <Autoff > can be activated.
•If the balance is not used for a longer time, take out the battery and store
it separately. Leaking battery liquid could damage the balance.

16 TFKB_B-BA-e-2210
7.6 Rechargeable battery operation (optional)
ATTENTION
The rechargeable battery and the battery match with each
other. Only use the delivered mains adapter.
Do not use the balance during the loading process.
The rechargeable can only be replaced by the same or by a
type recommended by the manufacturer.
The rechargeable battery is not protected against all
environmental influences. If the rechargeable battery is exposed
to certain environmental influences, it may set on fire or explode.

If the rechargeable battery starts to smell, being hot, changing
the colour or being deformed, it must be immediately unplugged
from mains supply and from the balance if possible.
7.6.1 Load rechargeable battery
The rechargeable battery pack (Option) is charged using the mains cable supplied.
Before the first use, the rechargeable battery package should be charged by
connecting it to the mains power cable for at least 15 hours.
To save the rechargeable battery, in menu (see chap.13.3.1.) the automatic switch-
off function <Autoff> can be activated.
If the capacity of the rechargeable batteries is exhausted, < Lo Bat> appears in
the display. Connect the power cable as soon as possible to load the rechargeable
battery. Charging time until complete recharging is approx. 8 h.

TFKB_B-BA-e-2210 17
7.7 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.
7.8 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,
rechargeable accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
7.9 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate 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 weighing system 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 display unit periodically in weighing operation.
•Arrange the required adjustment weight, see chap. 1.
Carry out adjustment as near as possible to the highest load of the balance
(recommended adjustment weight see chap. 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 [d]
of the balance. Info about test weights can be found on the Internet at:
http://www.kern-sohn.com
•Observe stable environmental conditions. A warm up time (see chapter 1) is
required for stabilization.
•Ensure that there are no objects on the weighing pan.
