2.3 Dimensions
3 Basic Information (General)
3.1 Proper use
The balance acquired by you serves to determine weight. 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 the goods to be weighed are
placed on the balance and the weight has been displayed.
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 pan. 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.
GAB-P-BA-e-1411 11
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
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.(www.kern-sohn.com). In KERN's accredited DKD calibration laboratory test
weights and balances may be calibrated (return to the national standard) fast and at
moderate cost.
12 GAB-P-BA-e-1411
4 Basic Safety Precautions
4.1 Pay attention to the instructions i n 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 German original document is binding.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and st orage
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 transport securing devices. (see chapter 6.2)
Secure all parts such as the glass wind screen, the weighing
platform, power unit etc. against shifting and damage.
GAB-P-BA-e-1411 13
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 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.
14 GAB-P-BA-e-1411
6.2 Unpacking / installation
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
Make sure that all transport locking devices are removed
To release the transport lock unscrew the transport screw
1 – non verifiable models or
2 –verifiable models
counter-clockwise.
For transportation carefully screw-in transport screw clockwise till to the stopper
and then fix it using locknut.
GAB-P-BA-e-1411 15
6.3 Scope of delivery
Serial accessories:
• Balance, see chap. 2
• Mains adapter
• Rechargeable battery
• Operating manual
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 KERN original mains adapter. Using other makes requires consent by
KERN.
6.5 Rechargeable battery operation
The rechargeable battery is charged via the delivered power supply.
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 12 hours.
The appearance of the battery symbol in the weight display indicates that the
battery is almost exhausted.
To charge the chargeable battery, connect the mains cable.
The LED display informs you during loading about the loading status of the
rechargeable battery.
• If the LED lights green, the rechargeable battery is fully charged.
• When the battery is being recharged, the LED lights red
6.6 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. 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.
16 GAB-P-BA-e-1411
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.
The adjustment is locked for verified balances. To disable the access lock,
requires that the seal is destroyed and the adjusting switch is actuated in
step 3 when turning on the scale. For position of adjusting switch, see chap.
6.10.1.
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.
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 pan.

or incorrect adjusting weight will be indicated by the error
message; repeat adjustment procedure.
6.10 Verification
UUGeneral hints:
According to EU directive 90/384/EEC balances must be officially 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 be verified and re-verified at 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 res ult 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.

6.11 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.
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.

7.7 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
so-called reference quantity). Counting is then carried out on the basis of the
calculated average piece weight.
The higher the reference quantity the higher the counting exactness.
Place reference quantity in weighing mode.
Press and the scales will change to quantity counting
mode; reference quantity of 10, „P 10“ will appear.
