4 Basic Information (General)
4.1 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.
4.2 Improper Use
Do not use balance for dynamic weighings. 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.
4.3 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
CXB/CXP-BA-e-0711
13
4.4 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.
5 Basic Safety Precautions
5.1 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.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
6 Transport and storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
6.2 Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts, e.g. weighing plate,
power unit etc., to prevent slipping and damage.

7 Unpacking, Setup and Commissioning
7.1 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.
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.
7.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.

Operating Manual Operating Manual
7.3 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.
7.4 Battery power supply The optionally supplied battery is charged with the supplied power supply.
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 15 hours. The battery has a service life of c. 200 hours
without background lighting or 60 hours with background lighting. The charging period for total charge is c. 8 hours
The appearance of the battery symbol in the weight display indicates that the
battery is almost exhausted. If no weighing process is carried out during the red LED
display, the balance will switch off automatically after about 20-30 minutes. Connect
the power adaptor as soon as possible to change the battery.
The LED display provides information about the battery's charging status.
red: Battery is almost discharged
green: Battery is completely discharged
7.5 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.

7.5.1 Start-up
Turn on scales with ON/OFF switch (left).
The balance will carry out a self-test As soon as the weight display shows "0" in all
the three display windows your balance is ready to weigh.
On CXP models (with RS 232) an internal number appears before the balance counts
down to zero.

7.5.2 Turn off – CXB models
• Turn off balance by operating the ON/OFF switch (left)
7.5.3 Turn off/standby mode – CXP models
• To turn off the balance for a long period of time use the ON/OFF switch
(left).
• To turn off the balance for a short period of time use the key.
To do this, press the key until "OFF" is displayed. Balance is in
standby mode (this avoids the required warm-up time). Restart the balance by
pressing the key.

7.5.4 Balance zero display
Environmental influences can lead to the exact figure of zero not being displayed in
spite of an empty weighing dish. It is, however, possible to reset your balance to zero
at any time and thus ensure that weighing really does commence at zero. Setting to
zero when a weight is applied is only possible within a certain type-dependent range.
In the event that the balance cannot be reset to zero with an applied weight, this
range has been exceeded (± 0,2 % max).
To reset the balance to zero, press key . A triangle [W ] pops up next to the [ a ]
symbol on the display.
7.5.5 Stability display
If a triangle [W ] pops up next to the [ ] symbol on the display,
the balance is in a stable state. If the status is instable the [W ] display disappears.
18
CXB/CXP-BA-e-0711
7.6 Adjustment with external weight
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.

The balance returns automatically into weighing mode. An error message will ap-
pear on the display should a adjustment error occur or should the adjustment
weight be incorrect. Turn balance off, then restart it and repeat the adjustment
process.
* The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data"). Weights of different nominal values may be used for adjustment but are not optimal for technical measuring.
Info about adjustment weights can be found on the Internet at: http://www.kernsohn.com

8 Parts counting
With parts 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.
8.1 Determination of the reference weight by weighing
