CFS/CCS-BA-e-1013 7
8 CFS/CCS-BA-e-1013
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
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“ 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 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. 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 appliance 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 electricity 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 rechargeable 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 required 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!

10 Counting
During piece counting parts can either be counted into a container or out of a container. To count a greater number of parts the average weight per part has to be
determined with a small quantity (reference quantity). The larger the reference
quantity, the higher the counting exactness.
High reference must be selected for small parts or parts with considerably different
sizes.
The average piece weight can only be determined by stable
weighing values.
If weighing values are under zero, the piece counter display shows a
negative number of items.
The exactness of the average piece weight can be increased at any time
during piece counting, by entering the displayed number of items and con-
firming by . After the reference optimization sounds a signal tone. As
the additional pieces increase the base for the calculation, the reference
also becomes more exact.
10.1 Determination of the average piece weight by weighing
Set reference
Reset balance to zero or tare the empty weighing container if necessary.
Place on the weighing plate a known number (e.g. 10 items) of individual pieces
as a reference.
Wait for the stability display, than enter the number of individual items via the numeric keypad.
Confirm within 5 sec by pressing
.
The balance determines the average piece weight.
Count the items
Tare if necessary, place weighing good and read off the number of items.
When an optional printer is connected, the displayed value can be edited by
pressing (menu settings „P mode“ „Print“ „Au OFF“, chpt. 12.2).
26 CFS/CCS-BA-e-1013
10.2 Numeric input of the average piece weight
Set reference
Enter the average piece weight via the numeric keyboard and acknowledge within
5 sec using button .
If in the weight display as weighing unit [kg] is active, the average piece weight
will be displayed in [g]. If as weighing unit [lb] is active, the average piece weight
is also displayed in [lb].
Count the items
Tare if necessary, place weighing good and read off the number of items.
When an optional printer is connected, the displayed value can be edited by
pressing (menu settings „P mode“ „Print“ „Au OFF“, chpt. 12.2).
10.3 Automatic reference optimization
If at the reference determination the placed weight or the placed piece number is
too small, in the display of the average piece weight the triangle symbol will appear
over [ ] or [ ] .
To optimize the calculated average piece weight automatically, add further parts
whose number is smaller than that of the first reference determination. After the reference optimization sounds a signal tone. For each reference optimization the average piece weight is newly calculated. As the additional pieces increase the base for
the calculation, the reference also becomes more exact.
By pressing the
key, recalculation can be avoided and the reference weight can
be blocked.
Automatic reference optimization will be deactivated as soon as the number of
added parts exceeds the saved reference quantity.

10.4 Counting with counting system
y y
Bulk material balance e.g. KERN
KFP
Reference balance KERN CFS
• Here pieces of huge quantities will
be counted.
• Due to its high resolution it is useful
for accurate determination of the
average piece weight.
• Big parts (max > 3kg) are counted
on the weighing bridge.
• Smallest parts (max < 3kg) are
counted on the precise KERN CFS.
• If in the determination of the average piece weight no such high
resolution is asked for as that of
the KERN CFS, the reference
formation can also be made in the
bulk material balance.
Zählen mit Mengenwaage:
1. On the reference balance KERN CFS set average piece weight, see chpt. 10.1.
or chpt. 10.2.
2. Switch-over balance with , see chpt. 8.3
3. Put empty vessel on the weighing plate of the bulk material balance KERN KFP
and tare.
4. Fill counted quantity in the vessel on the bulk material balance. The piece number is shown in the display.
In order to avoid errors at the piece number determination, both balances
must be adjusted with the same acceleration due to gravity (see chpt. 7.1 or
chpt.7.2). In case of non-compliance counting errors will result!
