3 Basic Information (General)
3.1Utilisation in accordance with specification
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 pan. 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 add-on weighing procedures, if small amounts of
goods to be weighed are removed or added. The “stability compensation“ installed
in the balance may result in displaying an incorrect measuring value! (Example:
Slowly draining fluids from a container on the balance.)
•Donotleavepermanentloadon theweighingpan. Thismaydamagethemeasuring
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.
•Neveroperate balancein explosiveenvironment.Theserialversionisnot 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 applications
•The appliance is modified or opened
•Mechanical damage or damage by media, liquids, natural wear and tear
•Improper setup or incorrect electrical connection
•The measuring system is overloaded

12 CIB-BA-e-2010
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
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 Transport and storage
5.1 Testing upon acceptance
When receiving the appliance,please checkpackagingimmediately, andthe 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.

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.
On the installation site observe the following:
•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 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 approx. 2 hours at
room temperature.
•Avoid static charge of goods to be weighed or weighing container.
•Do not operate in areas with hazard of explosive material or in potentially
explosive atmospheres due to materials such as gasses, steams, mists or
dusts.
•Keep away chemicals (such as liquids or gasses), which could attack and
damage the balance inside or from outside.
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, Scope of delivery
Remove device and accessories carefully from packaging, remove packaging material
and place device at the planned work place. Check if that there has been no damage
and that all packing items are present.

6.2.1 Placing
Level balance with foot screws until the air bubble of the
water balance is in the prescribed circle.
Check levelling regularly.
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.
If the LED next to this power supply unit symbol glows green, the power supply
unit is connected correctly.
6.4 Rechargeable battery operation
The optionally supplied battery is charged with the supplied power supply.
Before the first use, the rechargeable battery should be charged by connecting it to
the mains power supply for at least 14 hours. The rechargeable battery has a service
life of approx. 160 hours without background illumination or 90 hours with
background illumination. Charging time until complete recharging is approx. 14 h.
The appearance of the battery symbol in the weight display indicates that the
rechargeable battery is almost exhausted. If no load is placed during the red LED
display, the balance will switch off automatically after about 20-30 minutes. Connect
the mains adapter as soon as possible to charge the rechargeable battery.
•The appearance of the battery symbol in the weight display indicates that the
rechargeable battery is soon exhausted. Charge the battery with the help of the
supplied power pack.

6.5 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.

6.5.1 Start-up
Start balance by pressing .
After switch-on, the software version will appear shortly:
(example)
Afterwards the balance will carry out a segment test:
After that the balance will change automatically into the weighing mode, the zero
display appears in all three display windows and the balance is now ready for
operation:
If is pressed longtime during the segment test, the software date will
appear. Example: 2020-04-01.

16 CIB-BA-e-2010
6.5.2 Switch Off
Switch off balance using .
6.5.3 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 pops up next to the
symbol on the display.
6.5.4 Stability display
If in the display next to the symbol a triangle appears, the balance is in a
stable status. If the status is instable the display disappears.
6.6 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.
•Prepare adjustment weight, see chap. 1.
The adjustment weight you use is dependent on the capacity of the balance.
Perform adjustment as close as possible to the maximum load. Info about test
weights can be found on the Internet at: http://www.kern-sohn.com
•Observe stable environmental conditions. A warm up time (see chapter 1) is
required for stabilization.

7 Piece counting
With piece 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.
7.1 Determination of the reference weight by weighing
Set balance to zero and tare, as
required. Place a known number of
single parts on the balance as reference
weight. If the balance is stable, enter
the quantity of the placed parts on the
numeric keyboard. The input is shown
in the reference weight window; press
, the total weight of the parts, the
piece weight and the number of parts
are displayed.
(example)
Unload the weighing plate and place the
parts to be counted on the weighing
plate.
The weight of all parts, the piece weight
and the number of parts are displayed.

20 CIB-BA-e-2010
7.2 Numeric input of the reference weight
Unload the balance, enter the reference
weight via the numeric keyboard and
confirm by .
Now place the parts to be counted on
the weighing plate. All piece quantity
parameters are displayed.
(example)
7.3 Delete reference weight
Unload the weighing plate and press , the reference weight is deleted.
7.4 Automatic reference optimization
If it was impossible to determine a reference due to instable goods to be weighed or
an insufficient reference weight, the [] display will appear in the reference weight
window during reference calculation.
The overlay

indicates:
Placed number of pieces insufficient for reference calculation
< 40 d
Placed reference weight insufficient for reference calculation
< 4/5 d
Add additional parts now until the [] display disappears.
An audio signal indicates that reference optimization has been carried out.
At every reference optimisation, the reference weight is calculated anew. As the
additional parts increase the base for the calculation, the reference also becomes
more exact.
