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.

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.

CFS/CCS-BA-e-1825 25
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.
26 CFS/CCS-BA-e-1825
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.
CFS/CCS-BA-e-1825 27
8.1 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. Input the number of reference pieces via the number keys.
Wait for stability display and confirm with or (model CFS 50K-3) within 5 sec.
The scale shall detect the average piece weight and will then display the number of pieces.

8.3 Automatic reference op t imi zat io n
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 in cr eas e the base for the calculation, the reference also becomes more exact.
Pressing or (models CFS 50K-3), recalculation can be prevented and the reference weight can thus be blocked.
Automatic r eference optimization will be deactivated as soon as the number of added parts exceeds the saved reference quantity.
Some models allow this feature on or off in the menu.
CFS/CCS-BA-e-1825 33
8.4 Counting with counting system
(Illustration example)
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 platform.
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.
Counting with bulk material balance:
1. On the reference balance KERN CFS set average piece weight, see chap. 8.1. or chap. 8.2.
2. Switch over balance with (see chap. 7.3)
3. Put empty container onto bulk scales’ weighing plate and tare.
4. Fill counted quantity in the vessel on the bulk material balance. The piece number is shown in the display.
34 CFS/CCS-BA-e-1825
Display example model CFS 6K0.1:
In order to avoid errors at the piece number determination, both balances
must be adjusted with the same acceleration due to gravity (see chap. 14). In
case of non-compliance counting errors will result!

Provide required adjustment weight, cf. chapter 1. The adjustment weight to be used depends on the capacity of the weight / counting system. Implement adjustment as close to the maximum load as possible. Info about test weights can be found on the Internet at: http://www.kern-sohn.com
Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization.
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!

15 Linearization
Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range. If linearity deviation is discovered during a monitoring of test resources, you can improve this by means of linearization.
Carrying out linearization is restricted to specialist staff possessing well acquainted with the workings of weighing scales.
The adjustment weights to be used must be adapted to the weighing scale’s specifications; see chapter 3.4 “testing instruments control”.
Provide for required adjustment weights; cf. subsequent table 1 or table 2.
Observe stable environmental conditions. Stabilisation requires a certain
warm-up time.
After successful linearisation you will have to carry out calibration; see chapter 3.4 “testing instruments control”.
