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 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.
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
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 / return transport
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.
10
PLJ_N-BA-e-0930
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, 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.
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, remove plastic cover and setup
balance at the intended workstation.
PLJ_N-BA-e-0930

6.2.1 Placing
Design layout of weighing balance:
Assemble all parts as per illustration. To ensure earthing of weighing plate,
Place carrier (2) right at rear.
Models readability d = 1 mg: Models readability d = 10 mg:
2
Level balance with foot screws until the air bubble of the water
balance is in the prescribed circle
6.2.2 Scope of delivery
Serial accessories:
• Balance
• Mains power supply
• Operating Manual
• Draught shield (models providing readability of d =
1mg only)
• Hook for underfloor weighing
12
PLJ_N-BA-e-0930
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.
After connection to the power supply the balance will carry out a self-test. The
balance is ready for weighing when the weight display appears. If the display diverts
from zero, press the TARE-key.
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.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
6.5.1 Stability display
The appearance of the stability symbol [ ] on the display indicates that the
balance is in a stable state. If the status is instable the [ ] display disappears.
6.5.2 Balance zero display
If an exact zero reading is not displayed on the balance in spite of the weighing dish
being empty, press the TARE key and the balance will start resetting to zero [ a ]
.
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.

7.1 Automatic adjustment using internal weight
With the internal adjustment weight, the weighing accuracy can be checked and readjusted at any time.
The automatic adjustment function is always enabled. You can start adjustment at
any time by pressing the CAL-key manually.
Automatic adjustment is started each time
• after the weighing balance was disconnected from the mains
• when temperature changes take place
• at the end of a time interval
Temperature / time controlled adjustment is taking place:
5 minutes before the start of automatic adjustment, this will be announced by a "º C“,
(change of temperature) or a “►“ (after a certain time interval ends) symbol on the
display.
or
The user must complete his/her weighing process within this time.
After 5 minutes [ CAL 30 ] appears on the display.
This starts a “count down” of 30 seconds [ CAL 30 ] → [ CAL 0 ]. During these 30
seconds it is possible to cancel the adjustment by pressing the TARE key. This
makes the balance return to weighing mode in order to e. g. complete an unfinished
measurement.
After a further 5 minutes the automatic adjustment will restart and [ CAL 30 ]
appears.

7.3 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!
After verification the balance is sealed at the indicated positions.
Verification of the balance is invalid without the "seal".
22
PLJ_N-BA-e-0930
Position of the “official seals“:
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.

11.2 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.
As a rule:
The higher the reference quantity the higher the counting exactness.
