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“. (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. T he 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
CPB-N / CPB-DM-BA-e-1424 10
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.
Versions in other languages are non-binding translations.
The only binding version is the original document in German.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and stora ge
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.
CPB-N / CPB-DM-BA-e-1424 11
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, 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.
6.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
6.2.1 Placing
Level balance with foot screws until the air bubble of the
water balance is in the prescribed circle.
CPB-N / CPB-DM-BA-e-1424 12
Ensure that transport guard has been removed
(only existing in 6 kg models)
To loosen the transport guard screw out transport screw [1] anticlockwise.
For transportation carefully screw-in transport screw clockwise till to the stopper
and then fix it using locknut.

6.2.2 Scope of delivery
Serial accessories:
• Balance
• Weighing plate
• Power cable
• Protective cover
• Instruction Manual
6.3 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.
6.4 Rechargeable battery operation (optional)
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 12 hours. The operating time of the battery is
about. 70h. Charging time until complete recharging ca. 12h.
AUTO-OFF function can be selected after 3, 5, 15, 30 min. to save the rechargeable
battery (see chap.12).
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 hours, 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: Battery is almost discharged
green: Battery is completely discharged
6.5 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.
6.6 Initial Commissioning
A warming up time of 2 hours after switching on stabilizes the measuring values.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
CPB-N / CPB-DM-BA-e-1424 14
6.7 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.
Provide calibration weight, for details, see chapter 1 "Technical Data. "

CPB-N / CPB-DM-BA-e-1424 18
6.8 Linearization (non-verified models only)
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 testing instrument control, 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 test weights to be used must be adapted to the weighing scale’s
specifications; see chapter 3.4 “testing instruments control”.
• Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
• After successful linearization you will have to carry out calibration; see
chapter 3.4 “Testing instruments control”

6.9 Verification
General introduction:
According to EU directive 90/384/EEC balances must be verified if they are used as
follows (legally controlled area):
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the
medical and pharmaceutical laboratory.
c) For official purpose.
d) For manufacturing final packages.
In cases of doubt, please contact your local trade in standard.
After verification the balance is sealed at the indicated positions.
Verification of the balance is invalid without the "seal".
Verification notes:
An EU type approval exists for balances described in their technical data as
verifiable. If a balance is used where obligation to verify exists as described above, it
must verified and re-verified in regular intervals.
Re-verification of a balance is carried out according to the respective national
regulations. The validity for verification of balances in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
Balances with obligation to verify must be taken out of operation if:
•
The weighing result of the balance is outside the error limit. Therefore, in
regular intervals load balance with known test weight (ca. 1/3 of the max. load)
and compare with displayed value.
•
The reverification deadline has been exceeded.

2. Cover
3. Verification switch
4. Verification wire
6.10 Checking the balance verification settings
For the adjustment, the balance must be switched over to service mode.
In the service mode the parameters of the balance can be modified.
The service parameters may not be modified, as this could damage the
balance settings.
In calibrated scales the service mode is locked individually for each switch. To
disable the access lock, destroy the seal and actuate the switch. For position of
switch see chap. 6.9.1.
Attention:
After destruction of the seal the balance must be re-verified by an authorised agency
and a new verification wire/seal mark fitted before it can be reused for applications
subject to verification.

8 Piece counting
With pieces counting you can either count parts into a container or remove parts
from 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.
