3 Basic instructions
3.1 Proper use
The balance / counting system you purchased is intended to determine the
weighing value of material to be weighed. It is intended to be used as a “nonautomatic 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.
3.2 Improper Use
Do not use balance / counting system 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 /
counting system, minus a possibly existing tare load, must be strictly avoided.
Balance may be damage by this.
Never operate balance / counting system 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 dest r ucti on o f the balance.
The scale / the counting system may only be used according to the described
preconditions. 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 ope ne d
• 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
18 CFS/CCS-BA-e-1825
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.
All language versions contain a non-binding translation.
The original German is binding.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 T ransport 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.
CFS/CCS-BA-e-1825 19
6 Unpacking, Setup and Commis si oning
6.1 Installation Site, Location of Use
The balances / counting systems 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 /
counting system.
On the installation site observe the following:
• Place the balance / counting system 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 / counting system against high humidity, vapours and
dust;
• Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (co nd ens a ti on o f air humidi ty 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, Scope of delivery
Remove device and accessories carefully from packaging, remove packaging
material and place device at the planned work place. Verif y that there has been no
damage and that all packing items are present.
6.2.1 Scope of delivery / serial accessories

Install weighing plate and wind screen, if applicable, if needed.
Level balance with foot screws until the air bubble of the water balance is in
the prescribed circle.
Check levelling regularly
Interconnect reference scale and bulk scales via the second-scale interface
in the counting systems KERN CCS.
6.4 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.
6.5 Rechargeable battery operation (optional)
The rechargeable battery is charged via the delivered power 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.
To save the rechargeable battery, in the menu (see chap.12.2) the automatic
switch-off function [„ “ „ „] can be activated, switch-off time selectable
according to 0, 3, 5, 15, 30 minutes.
If an arrow appears on the weight display [] 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. Charging time until
complete recharging is approx. 12h.
The LED display informs you during loading about the loading status of the
rechargeable battery.
red: Voltage has dropped below prescribed minimum. Connec t mains
adapter to load the rechargeable battery.
green: Rechargeable battery completely reloaded
yellow: Rechargeable battery very low. Connect mains adapter as soon as
possible to load the rechargeable battery.

6.6 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.
6.7 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.
6.8 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordina ted - 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 see chapter 14.

7 Basic Operation
7.1 Switching on/off
Actuate power switch (cf. chapter 2) at the right bottom of the scale to the front.
The balance will carry out a self-test As soon as the weight display appears, the
balance is ready for weighing.
To switch-off push backward the switch-on/switch-out on the right lower side of
the balance.
7.2 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 12.
When using as counting system the zeroing range of both balances can be set in
the menu, see chapter 13.
Manual
Unload the balance
Press , the balance starts resetting to zero.
The [] symbol over a appears.
Automatic
In the menu the automatic zero point correction can be switched off or the amount
can be changed, see chapter 13.
7.3 Switching over reference scale bulk scales if used as counting system
For piece counting a platform can be connected via the second balance interface. 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.
By pressing the display changes from one to the other balance.
In the display appears or .
The appeared [] displays the active balance.

7.4 Weighing with tare
A tare value can be entered for the reference as well as for the bulk material
balance. Before setting a tare value select active balance,
see chap. 9.3.
7.4.1 Taring
Deposit weighing vessel. After successful stop check press the TARE button.
Zero display and the indicator [] above NET appear.
The weight of the container is now internally saved.
Weigh the material, the net weight will be indicated.
After removing the weighing container, the weight of the weighing container
appears as negative display.
To delete the tare value, remove load from weighing pan and press the TARE-
key.
The tare procedure can be repeated as many times as necessary, for example
with initial weighing of several components for a mix (add-on weighing). The
limit is reached when the total weighing range capacity is full.
7.4.2 Numeric entering of tare weight
Unload and reset to zero the balance.
Input known tare weight via the numeric keys with decimal point, and confirm
with TARE key. The entered weight will be stored as tare weight and displayed
with negative sign. The indicator [] above NET appears.
Put the filled weighing container on the balance, the net weight will be
displayed.
The tare value remains stored until it is deleted with the TARE key.
The tare value will be rounded up according to the readability of the balance,
e.g. at a balance 60 kg max/5 g readability the input value of 103 g will be
displayed as -105 g.
7.4.3 Switch-over weighing unit
Depending on the model, pressing the UNIT key may switch over between g / kg
lb (only with menu adjustment F1 oFFUnit kg / lb).
The indicator [] shows the active unit.

8 Parts counting
Before the balance can count parts, it must know the average part weight (i.e.
reference). Proceed by putting on a certain number of the parts to be counted. The
balance determines the total weight and divides it by the number of parts, the socalled reference quantity. Counting is then carried out on the basis of the calculated
average piece weight.
As a rule:
The higher the reference quantity the higher the counting exactness.
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 precision of the average unit weight can be increased at any time
while units are being counter by inputting the displayed number of units
and confirming by or (in CF S 50K-3 models). After the
reference optimization sounds a signal tone. As the additional p ieces
increase the base for the calculation, the reference also becomes more
exact.
