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
PFB-BA-e-0912 7
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,
power unit 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.
8 PFB-BA-e-0912
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.
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
Carefully remove the balance from the packaging and setup balance at the intended
workstation.
6.2.1 Placing/ Remove the transportation lock
The balance must be installed in a way that the weighing plate is exactly in horizontal
position.
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 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.
6.5 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.
6.6 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.
6.7 Adjusting
The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data").
10 PFB-BA-e-0912
Procedure when adjusting:
Observe stable environmental conditions.
A warming up time (see chapter 1; Technical Data) is required for stabilization.
Ensure that there are no objects on the weighing plate.
Balance display Operation
Ö In weighing mode press approx. 3 sec. until
When display „LoAd“ appears, put the necessary
adjustment weight (see chap.1; Technical Data) on the
center of the weighing plate.
Adjustment will be carried out automatically after dead
stop control.
„UnLoAd“ appears.
Ö Wait for stability display
„Pass“ appears, the adjustment process has been
finished successfully.
Ö Take away adjustment weight
Wait until the balance is again in the weighing mode.

8.3 Parts counting
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.
The higher the reference quantity the higher the counting
exactness.
Balance display Operation
Ö Start balance by pressing
The balance will carry out a self-test.
Wait for „0.0“ display.

Appears the reference quantity „10“.
By pressing the key several times, the
reference quantities 10, 20, 50, 100, 200 can be set

Ö Press
„ACC 2“ is shortly displayed
Then appears for 2 seconds the weight of both test
items, before the weight of the second test item will
appear again.
In order to delete the stored values, press and as long as the sum
of the test items is displayed, press , the balance will return to
„0.0g“.
