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 mate-
rial 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
Do not use balance for dynamic weighing. In the event that small quantities are re-
moved or added to the material to be weighed, incorrect weighing results can be
displayed due to the “stability compensation“ in the balance. (Example: Slowly
draining fluids from a container on the balance.)
Do not leave permanent load on the weighing plate. This may damage the measur-
ing 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 dam-
age 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 weigh-
ing 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 bal-
ance and, if applicable, the testing weight, must be checked regularly. The respon-
sible user must define a suitable interval as well as type and scope of this test. In-
formation 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.
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 Transportation & Storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appli-
ance itself when unpacking for possible visible damage.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly required re-
turn.
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 plat-
form, 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 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, vapors 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.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static elec-
tricity accumulations or instable power supply occur. Change location or remove
source of interference.
6.2 Unpacking/erection
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
Level balance with foot screws until the air bubble of the water balance is in the
prescribed circle.
When using as counting system balance and weighing bridge must be levelled.

6.5 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.
6.6 Rechargeable battery operation
The internal battery is charged with the supplied mains cable.
Before the first use, the rechargeable battery should be charged by connecting it to
the mains power cable for at least 15 hours. The operation time of the rechargeable
battery is approx. 70 hours. When connecting a second balance, the operation time
will be reduced. The charging period for total charge is c. 12 hours
To save the rechargeable battery, in the menu (see chap.12.2) the automatic
switch-off function [„ “ „ „] can be activated, switch-off time selectable
after 0, 3, 5, 15, 30 minutes.
If an arrow appears on the weight display [T]above the battery symbol or "bat
lo" when turning on the balance, this is an indication that the capacity of the re-
chargeable battery will soon be exhausted. The balance will be ready to operate for
about another 10 hrs., then it will switch off automatically. Connect the power cable
as soon as possible to load the rechargeable battery.
The LED display under the piece number window informs you during charging about
the charging status of the rechargeable battery.
red: Voltage has dropped below prescribed minimum. Connect mains
adapter to load the rechargeable battery.
green: Rechargeable battery is completely charged
yellow: Rechargeable battery very low. Connect mains adapter as soon as pos-
sible to load the rechargeable battery.
6.7 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.
6.8 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, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
16 CFS/CCS-BA-e-1013

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.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is re-
quired for stabilization. Ensure that there are no objects on the weighing plate.
•Info about adjustment weights can be found on the Internet at:
http://www.kern-sohn.com
•In order to avoid errors at the piece quantity determination, both balances
must be adjusted with the same acceleration due to gravity.
In case of non-compliance counting errors will result!

8.2 Zeroing
Resetting to zero corrects the influence of light soiling on the weighing plate. The
resetting range of the balance was adjusted to ± 2% max. by factory.
Further adjustments are possible in the menu, see chapter 13.
When using as counting system the zeroing range of both balances can be set in
the menu, see chapter 13.
Manual

8.3 Switch over balance/weighing bridge
For piece counting a weighing bridge can be connected via the second balance in-
terface. In the counting system KERN CCS the quantity counting is made on the
bulk material balance KERN KFP. The reference balance KERN CFS permits due
to its high resolution a very precise determination of the average piece weight.
The second balance can be operated in the same manner like the first balance.
