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 add-on weighing procedures, if small amounts of
goods to be weighed are removed or added. The “stability compensation“ installed in
the balance may result in displaying an incorrect measuring value! (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 dammage or dammage by media, liquids, natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
Page 9
PLT-BA-defsi-0510
78
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 Transport and 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, vapours 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.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.
7.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
Page 11
PLT-BA-defsi-0510
80
7.2.1 Setup
Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.
Models d = 10 mg Models d = 1 mg
7.2.2 Scope of delivery
Serial accessories:
• Balance
• Weighing plate
• Mains power supply
• Operating Manual
• Glass wind screen
7.3 Mains connection
Power is supplied via the external mains power supply. The stated voltage value
must be the same as the local voltage.
Only use original KERN mains power supplies. Using other makes requires consent
by KERN.
7.4 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.
7.5 Initial Commissioning
A warming up time of 15 minutes 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.

8.3.1 P1 Calibration (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.
Using the inbuilt adjusting weight the balance automatically carries out an adjustment
after any temperature change of 3 °C or any time it was disconnected from the power
supply.
Of course it is also possible to check the accuracy of the balance manually any time.
You can choose between two options:
1. Adjustment is started by pressing the F-key three times.
After successful adjustment the balance automatically returns to weighing
mode.
2. Under menu item “P1 01 Adjustment with internal weight” (see table below)
Procedure when adjusting:
Observe stable environmental conditions. A warming up time of ca. 1 hour is required for stabilization.
Note!
During the adjustment process no objects should be on the weighing plate.

8.3.1.1 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 verifyable. 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!
After verification the balance is sealed at the indicated positions.
Verification of the balance is invalid without the "seal".

Position of the “official seals“:
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.

8.3.2 P2 GLP (Good laboratory practice)
Quality assurance systems require printouts of weighing results as well as of correct
adjustment of the balance stating date and time and balance identification. The easiest way is to have a printer connected.

9.1.1.2 Underfloor weighing
Underfloor weighing enables you to weigh objects that cannot be placed on the
weighing plate due to their size or shape.
Proceed as follows:
• Switch off balance.
• Open the closing lid on the bottom of your balance.
• Suspend hook for underfloor weighing carefully and completely.
• Place your balance over an opening.
• Suspend the goods to be weighed from the hook and carry out the 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.
NOTICE
After completing the underfloor weighing the opening on the bottom of the balance
must always be closed (dust protection).

9.1.2 Parts Counting
Before the balance can count parts, it must know the average part weight (i.e. reference). This is either entered manually or determined by weighing. 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 so-called 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.

12 Instant help
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:
Fault Possible cause
The displayed weight does
not glow.
• The balance is not switched on.
• The mains supply connection has been interrupted
(mains cable not plugged in/faulty).
• Power supply interrupted.
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.
•
Electromagnetic fields / static charging (choose
different location/switch off interfering device if
possible)
Should other error messages occur, switch balance off and then on again. If the error
message remains inform manufacturer.
