2 Basic Information (General)
It is absolutely necessary that you read and understand the operating instructions prior to
installation and commissioning and follow the instructions during the process!
2.1 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.
2.2 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“ 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 sys-
tem.
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 pro-
tected.
The structure of the balance may not be modified. This may lead to incorrect weighing re-
sults, 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.
2.3 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 and damage caused by media, liquids
-natural wear and tear
-The appliance is improperly set up or incorrectly electrically connected
-The measuring system is overloaded
2.4 MonitoringofTest 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
de-fine a suitable interval as well as type and scope of this test. Our accredited DKD
calibration laboratory offers fast and inexpensive adjustment for test weights and weighing
balances (reset to na-tional normal weight).

3 Basic Safety Precautions
3.1 Pay attention to the instructions in the Operation Manual
Carefully read this operation manual before setup and commis-
sioning, even if you are already familiar with KERN balances.
3.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
4 Transportation & Storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance it-
self when unpacking for possible visible damage.
In case of visible damage have the damage verified by the messenger’s signature. Do not
alter goods or packaging and do not remove any parts of the delivery. Report the damage
immediately (within 24 hours) in writing to the parcel service.
4.2 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.
5 Unpacking, Setup and Commissioning
5.1 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.

FKA-BA-e-1616 7
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, vapors 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, accli-
matize the disconnected appliance for ca. 2 hours at room temperature.
- Avoid static charging of the material to be weighed, weighing container and wind-
shield.
If electro-magnetic fields or static charge occur, or if the power supply is unstable major de-
viations on the display (incorrect weighing results) are possible. In that case, the location
must be changed.
5.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup balance
at the intended workstation.
5.2.1 Placing
Level balance with foot screws until the air bubble of the water bal-
ance is in the prescribed circle.
5.3 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.
5.4 Battery operation
 To insert the batteries (6 x 1.5 V) remove the battery compartment cover. Remove
it with the help of a coin.
 In the each battery tube insert three batteries in the same polarity sense.
 Screw down again the battery cover.
To save the battery, the background illumination can be switched off (G23).
If the battery voltage drops below a critical value for operational safety, turns off the scale.

5.6 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 acces-
sories and peripheral devices by KERN, as they are ideally tuned to your balance.
5.7 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”.
5.8 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 during the initial start-up, after change in location and variation of surrounding
temperature. To receive accurate measuring values it is also recommended to adjust the
balance periodically in weighing operation.
5.9 Adjustment
With an adjustment weight, the weighing accuracy can be checked and re-adjusted at any
time.
Attention: In the verified balances the adjustment is not possible.
Procedure when adjusting:
Observe stable environmental conditions. A short warming up time of ca. 15 minutes is rec-
ommended for stabilization.
5.10 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 purposes
d) For manufacturing final packages
In cases of doubt, please contact your local trade in standard.
Verification instructions
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!
