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 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.

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.

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 Battery power supply
The balance is fitted with rechargeable NiMH R6 (AA) batteries and plug-in power
pack as standard.
Use the provided power pack for battery charging.
During initial operation it is very important to charge the batteries for c. 12 hours.
Afterwards discharge the batteries completely 3 times (watch display message and
automatic disconnection) and recharge. If this is done, the life of the batteries will be
increased and the nominal capacity of the batteries reached.
For operation with rechargeable batteries the balance has some functions which can
be activated or deactivated in the menu; see Section 12.4.
If the AUTO-OFF function is activated, the balance switches off automatically to save
the rechargeable batteries after 5 minutes without load change.
If the symbol
or “bat lo" appears in the display when switching on the balance, this
means that the capacity of the rechargeable batteries will soon be exhausted, charge
the rechargeable batteries as soon as possible.

6.6 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.
6.7 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.

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.
Procedure when adjusting:
Adjustment should be carried out by using a recommended adjustment weight.
(See chpt. 1 “Technical specifications“):
Observe stable environmental conditions. A warm-up time of 2 hours is necessary for
stabilisation.

This function is used to tare small variations in weight automatically.
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. (e.g. slow flow of liquids from a container placed on
the balance, evaporating processes).
When apportioning involves small variations of weight, it is advisable to switch off this
function.

13.2 Quantities (Function P4.3 PcS)
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.

Input of minimum weight "P2.2 S_Lo"
The minimum weight affects the following functions:
Automatic taring (chap.13.5):
In order to apply this function, the weight of the weighing plate must have dropped
below the entered weighing value first, before another greater weight can be tared
automatically.
Automatic output function "rEPL" (chap. 14.2.2):
If the current weighing value exceeds the entered weighing value, a weighing value
will be issued automatically. The next weighing value will not be issued unless the
weighing value has meanwhile dropped below the entered weighing value.
For animal weighing see chap. 13.8
If the minimum weight is exceeded, weighing starts automatically.
