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 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 system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
plate, 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
SFB-BA-e-1324
14
3.4 Monitoring of Test Resources
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 glass wind screen, weighing
platform, power unit etc. against shifting and damage.
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.
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 Transportation & Storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.

Instruction Manual
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, vapors and dust;
Do not expose the balance to strong humidity for extended periods. 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.
Being of protection type IP 67 as per DIN EN 60529, the weighing scale is
suitable for short-term use in wet conditions.
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.
6.2 Unpacking/implantation
Scope of delivery / serial accessories:
Carefully remove the balance from the packaging, remove plastic cover, assemble
the tripod and the display unit (see chap. 6.2.1) and setup balance at the intended
workstation.
SFB-BA-e-1324
16
Remove the transportation lock:
As the air bubble is located under
the weighing plate, remove it.
Level balance with foot screws until
the air bubble of the water balance
is in the prescribed circle.
1. Models platform size 300 x 240 mm
Remove the marked screws.
2. Models platform size 400 x 300 mm
Remove the screw marked by the label .
Attention: The sealed screws must not be unscrewed.
Accurate weighing results require a weighing bridge with perfect horizontal
alignment. During initial installation and after each change of work area it is
necessary to level the weighing bridge.

6.3 Mains connection
red:
Voltage has dropped below prescribed minimum.
green:
Rechargeable battery is completely charged
yellow:
Charging storage battery
IP65 protection is only ensured during operation on battery
power.
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.
6.4 Rechargeable battery operation
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 12 hours.
The symbol appearing on the weight display indicates that the battery is
getting low. Approximately 10 h of instrument usage are left; afterwards it will shut
off automatically. Use the supplied battery charger for charging the battery.
Charge status of rechargeable battery is indicated by the LED display.
To save battery life, you can enable the automatic switch-off function "AUTO OFF",
see chap. 7.14.
6.5 Protection type IP65
Designed for temporary contact with liquids. Use a damp cloth for cleaning.
Dustproof.
SFB-BA-e-1324
21
In weighing systems with a resolution of < 15 000 dividing steps an
adjustment is recommended.
In weighing systems with a resolution of > 15 000 dividing steps a
linearisation is recommended (see chap. 6.6).
Prepare the required adjustment weight. The weight to be used
depends on the capacity of the scale. Carry out adjustment as near as
possible to the scale’s maximum weight. Info about test weights can be
found on the Internet at: http://www.kern-sohn.com.
Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
6.6 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate 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 weighing system 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 display unit periodically in weighing operation.
SFB-BA-e-1324

6.6.1 Verified models
In verified weighing systems the menu item for adjustment „P2 mode“ is
blocked.
To override the blocked access you will have to destroy the seal before calling
up the menu and to short-circuit the two contacts on the circuit board [K2],
using a jumper (See chap.6.7).
Attention:
After destruction of the seal the weighing system 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.

6.7 Linearization
In balances with a resolution of > 15 000 dividing steps carrying out a
linearisation is recommended.
Carrying out linearization is restricted to specialist staff possessing
well acquainted with the workings of weighing scales.
The test weights to be used must be adapted to the weighing scale’s

6.8 Verification
Verification of the weighing system is invalid without the "seal".
[K1]
[K2]
General introduction:
According to EU directive 90/384/EEC or 2009/23EG 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.
Verification notes:
An EU Qualification Approval is in existence for verified weighing systems. If a
balance is used where obligation to verify exists as described above, it must be
verified and re-verified at regular intervals.
Reverification is carried out according to the relevant national statutory 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!
Notes on verified models
Access to conductor plate:
Remove seal
Open display unit
The application of the display unit as a weighing system able to be verified
requires that the contacts of the circuit board are short-circuited with the help
of a jumper [K1]. For non verifiable models remove the jumper.
To adjust, short-circuit the contacts of the circuit board, using a jumper [K2].

demanded by the set reference quantity and confirm by
The weighing scales calculate the reference weight. The
current quantity (such as 100 items) will be displayed.
Remove reference weight. The balance is from now in parts
counting mode counting all units on the weighing plate.
Back to Weighing mode by .
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 socalled reference quantity. Counting is then carried out on the basis of the calculated
average piece weight.
As a rule:
The higher the reference quantity the higher the counting exactness.

Weighing data can be issued according to menu settings either via the RS 232C
interface or by pressing via the interface.
This data exchange is asynchronous using ASCII - Code.
The following conditions must be met to provide successful communication between
the weighing balance and the printer.
Use a suitable cable to connect the weighing balance to the interface of the
printer. Faultless operation requires an adequate KERN interface cable.
Communication parameters (baud rate, bits and parity) of balance and printer
must match. For detailed description of interface parameters see chap. 8,
menu block „P1 COM“ or „P2 COM“.

Fault
Possible cause
The displayed weight does
not glow.
The balance is not switched on.
Mains power failure (mains cable defective).
Power supply interrupted.
(Rechargeable) batteries are inserted incorrectly or
empty
No (rechargeable) batteries inserted.
The displayed weight is
permanently changing
Draught/air movement
Table/floor vibrations
Weighing plate has contact with other objects.
Electromagnetic fields / static charging (choose
different location/switch off interfering device if
possible)
The weighing result is
obviously incorrect
The display of the balance is not at zero
Adjustment is no longer correct.
Great fluctuations in temperature.
Warm-up time was ignored.
Electromagnetic fields / static charging (choose
different location/switch off interfering device if
possible)
In case of an error in the program process, briefly turn off the balance and
disconnect from power supply. The weighing process must then be restarted from
the beginning.
Help:
Should other error messages occur, switch balance off and then on again. If the error
message remains inform manufacturer.
