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 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 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
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.

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.
5.2 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,
mains adapter etc., to prevent slipping and damage.
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.
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 and weighing container.

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/erection
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
The balance must be installed in a way that the weighing plate is exactly in horizontal
position.
Level balance with foot screws until the air bubble of the
water balance is in the prescribed circle.

6.3 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.

6.4 Operation using a (rechargeable) battery (optional)
Lift-off the battery cover on the lower side of the balance. Connect 9 V compound
battery.
Replace the battery compartment cover.
For battery operation the balance has an automatic switch-off function which can be
activated or deactivated in the menu (chapter 9).
ÖIn weighing mode keep the PRINT-key pressed until [Unit] appears.
ÖPress MODE key repeatedly until „AF“ appears.
ÖUse the SET key, to confirm.
ÖUse the MODE key to choose between the two following settings:
„AF on“: In order to save the battery, the balance switches automatically
off after 3 minutes without weighing.
„AF off“: Switch-off function deactivated.
ÖUse the SET key to confirm. The balance returns to weighing mode.
If the batteries are run down, "LO" appears in the display. Press ON/OFF-key and
replace the batteries immediately.
If the balance is not used for a longer time, take out the batteries and store them
separately. Leaking battery liquid could damage the balance.
If there exists an optional rechargeable battery, it has to be connected in the battery
compartment via a separate plug-in socket. Now the mains adapter delivered with the
rechargeable battery must be applied.
6.5 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.

PCB-BA-e-0914 15
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. 1). 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.
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.
6.8 Adjustment
The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data"). Adjustment is also possible with the weights of other
nominal values (see table 1), but not the optimum for measuring technique.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
ÖTurn on balance by pressing the ON/OFF key.
ÖPress the MODE key and keep it pressed, in the display appears shortly
„CAL“. After that the exact size appears flashing in the display (see
chapter.9.3) of the adjustment weight.
ÖNow set the adjusting weight in the centre of the weighing plate.
ÖPress the SET key. Short time later there appears „CAL F“, then the
automatic return to the weighing mode. In the display there appears the
value of the adjustment weight.
An error during adjustment or the use of an incorrect adjusting weight will
result in an error message „CAL E“. Repeat adjustment.
Keep the adjustment close to the balance. Daily control of the weighing exactness is
recommended for quality-relevant applications.

6.9 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
•Open closing cover at the balance bottom.
•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).

Parts counting
MODE
CAL
SET
M
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 larger the reference quantity, the more accurate the parts
counting.
The process has four steps:
Tare the weighing container
Determine the reference unit
Original weighing of reference weight
Count the items
ÖIn weighing mode press MODE key shortly. Reference
piece number „5PCS“appears flashing.
ÖBy pressing the MODE button several times other reference
quantities 5, 10, 20, 25 and 50 can be called up. Place as
many pieces to count on the weighing plate as the set
reference quantity requires.
ÖUse the SET key to confirm. The balance is now in parts
counting mode counting all units on the weighing plate.
