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 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“. (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.
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. 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 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.
RPB_D-BA-e-1425 11
6 Unpacking, Setup and Comm issioning
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.

6.4 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 Battery power supply (option) 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 15 hours.
• If an arrow appears on the weight display [] above the battery symbol , 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. Charge the battery with the help of the supplied
power pack.
• If in the weight display appears „bat Lo“ followed by a flickering display, the
capacity of the rechargeable battery is below the prescribed minimum. The
balance will be ready to operate for about another 5 minutes, then it will switch off
automatically. Charge the battery with the help of the supplied power pack.
The LED display informs you during loading about the loading status of the
rechargeable battery.

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.
RPB_D-BA-e-1425 14
6.7 Adjustment
The adjustment is locked for verified balances. Carrying out adjustment
be reused for applications subject to verification.
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.
requires that the seal is destroyed and the adjusting switch is confirmed in
step 3 when turning on the scale. For position of adjusting switch, see chpt.

6.8 Verification
•
•
UUGeneral:
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 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 wi th obl i gation to verify must be taken out of operation if:
The weighing re sult 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.
