4 Basic Information (General)
4.1 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.
4.2 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“ 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 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.
4.3 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
4.4 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 Basic Safety Precautions
5.1 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.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
6 Transportation & Storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
6.2 Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts, e.g. weighing plate,
power unit etc., to prevent slipping and damage.
7 Unpacking, Setup and Commissioning
7.1 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, 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, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
• Avoid static charge of goods to be weighed or weighing container.
AES/AEJ-BA-e-0912
14
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.
7.2 Unpacking and erection
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.

Ö Levelling balance
Level balance with foot screws until the air bubble of the
water balance is in the prescribed circle.
Ö 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.
7.3 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 accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.

7.4 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).
To adapt the balance to ambient conditions, open wind screen doors.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
8 Basic Operation
8.1 Switching on/off
If the (*) sign can be seen, the balance is being supplied with power via the mains adaptor.
Turn on balance by pressing the ON/OFF key. The
balance will carry out a self-test The balance is ready
for weighing when the weight display appears.
The weighing balance will start in the mode it was in
when last switched off, e. g. piece counting.
Turn off balance by pressing the ON/OFF key.
Symbol (*) appears.

8.2 Simple weighing
Ö Place goods to be weighed on balance.
Ö Wait until the stability display appears [|].
Ö Read weighing result.
If the display shows the stability display [|] the balance is in a stable status. If the status is instable the
[|] display disappears.
Observe stable environmental conditions.

8.7 Underfloor weighing
Objects unsuitable for placing on the weighing scale due to size or shape may be
weighed with the help of the flush-mounted platform.
Proceed as follows:
• Switch off the balance
• Remove the weighing pan and carefully turn over the weighing balance.
• Loosen screw, turn cover plate (1) by 90º and reattach with the help of
the screw.
• Suspend hook for underfloor weighing carefully and completely.
• Place weighing balance over an opening.
• Attach load to hook and carry out weighing procedure.
Fig. 1: Setup of balance for underfloor weighing
CAUTION
▬ Always ensure that all suspended objects are stable enough to
hold the desired goods to be weighed safely (danger of breaking).
▬ Never suspend loads that exceed the stated maximum load (max)
(danger of breaking)
▬ Always ensure that there are no persons, animals or objects that
might be damaged underneath the load.
After completing the underfloor weighing the opening on the bottom of
the balance must always be closed (dust protection).

9 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.
Observe stable environmental conditions. A warming up time (see chapter 1)
is required for stabilization. Ensure that there are no objects on the weighing
plate.

9.7 Verification
General introduction:
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 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 officially 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!
Verification of the balance is invalid without the "seal".
Balances with obligation to verify must be taken out of operation if:
• The weighing result 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.

9.7.1 Verification switch and seals
Prior to verification you will have move the calibration switch to verification position
(See direction of arrow, fig. 1). In this position the display shows a bracket around
the last display point.
After verification the balance is sealed at the indicated positions.

11.2 Parts counting
During piece counting parts can either be counted into a container or out of 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.
The process has four steps:
• Tare the weighing container
• Determine the reference unit
• Original weighing of reference weight
• Count the items

11.5 Density determination of solids (hydrostatic weighing)
Density is the relationship of weight [g] : volume [cm3]. The weight is determined by
weighing the sample in air. The volume results from the ascending force [g] of the
sample dipped in a liquid. The density [g/cm3] of that liquid is known (principle of
Archimedes).
1. How to prepare the weighing balance
The density is determined with help of the underfloor
weighing device.
Prepare the balance as follows:
• Switch off the balance
• Remove the weighing pan and carefully turn
over the weighing balance.
• Screw-in hook for underfloor weighing (option)
• Place weighing balance over an opening.
• Attach sample holder (1)
• Fill measuring liquid (2) in a vessel e.g. beaker
and temper it.

11.7 Weighing with tolerance range
11.7.1 General
This balance can be used as dispensing as well as sorting balance; the respective
lower tolerance limit as well as upper tolerance limit can be programmed. An acoustic signal supports portioning, dispensing or sorting.
Tolerance weighing function in menu (see chpt. 10.1):
[2.SEL.2]
or activate the combination tolerance weighing/adding (tolerance control on
the respective poured quantity):
[2. SEL.3]
Entering limits is possible for the following functions:
• Weighing
• Parts counting
• Percent determination
• Weighing with freely programmable weighing unit
There are two different ways to carry out evaluation of limits:
1. Evaluation of absolute values [24. TXP.1]:
An exact reference value (e.g. 1 kg) is set.
2. Evaluation with difference values [24. TXP.2]:
An upper limit and a lower limit for a reference value are set.
Example:
Reference value Lower limit Upper limit
Poured quantity 100.0000 g 97.0000 g 105.0000 g
Evaluation of absolute
values
100.0000 g 97.0000 g 105.0000 g
Evaluation with
difference values
100.0000 g -3.0000 g 5.0000 g
AES/AEJ-BA-e-0912
55
There are two different ways to set the tolerance limits:
1. By weighing, that is by placing item on weighing balance and saving this
value.
2. Numeric entry of values via keyboard
• If a limiting value was set it remains saved until the balance is turned off.
• For the functions weighing, counting, percent individual limits can be set.
• When entering limits, pay particular attention to the type of classification
set (absolute/differential values).
11.7.2 Display of the results

Remarks:
• The performance delivered by the output control via the commands “O0~O7” or
setting the weighing balance functions is the same.
• Models “O8 and O9“ are specifically designed for input commands.
• Once a command of "O0~O9” has been executed its status will remain enabled
until the next command is given. However, after turning off the weighing balance
output control returns to initial setting.
15 Printer mode
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 (Baudrate, bits and parity) of weighing balance
and printer have to match, see chpt. 10.1.5 “Settings for serial interface”.
