3 Basic Information (General)

3.1 Proper use

The display unit acquired by you is used in combination with a load cell and serves to
determine the weighing value of material to be weighed. It is intended to be used as
a “non-automatic weighing system”, 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 weighing system 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 display unit. (Example: Slowly
draining fluids from a container on the balance.)
Do not leave permanent load on the weighing pan. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
plate, minus a possibly existing tare load, must be strictly avoided. Both, the w ei g hi ng
plate and the display unit may be damaged during this process.
Never operate display unit in explosive environment. The serial version is not
explosion protected.
Changes to the display unit's design are not permitted. This may lead to incorrect
weighing results, safety-related faul ts and des tr uct ion of the display unit.
The display unit may only be operated in accordance with the described default
settings. 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

12 KXS/KXG-TM-BA_IA-e-1420

3.4 Monitoring of Test Resources

Keep all parts of the original packaging for a possibly required

and remove loose/mobile

Secure all parts such as the glass wind screen, the weighing

In the framework of quality assurance the measuring-related properties of the display
unit 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 display units’ test substances and the test weights required for this. In
KERN’s accredited DKD calibration laboratory test weights and display units 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.

 All language versions contain a non-binding translation.

The original German is binding.

6 Unpacking and placing

• For display unit, see chapter 2

6.1 Installation Site, Location of Use

The display units are designed in a way that reliable weighing results are achieved in
common conditions of use.
Precise and fast work is achieved by selecting the right place for your display unit
and your weighing plate.
On the installati on site obs erve the following:

• Place the weighing system 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 display unit and the weighing plate against direct dra ft fr om ope n
windows or doors.

• Avoid jarring during weighing;

• Protect the display unit and the weighing plate against high humidity, vapours

and dust.

• Do not expose the display unit 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 and placing

Take the display unit carefully out of its packaging, remove the plastic jacket and
install it at the designated work space. Mount the displ ay unit in a way that facilitates
operation and where it is easy to see.

6.3 Scope of delivery / serial accessories:

• Plug for connection to load cell

• Operating manual

14 KXS/KXG-TM-BA_IA-e-1420

6.4 Transport Securing

Remove the transportation safety device at the four marked positions:

Transport Securing

6.5 Placing

Mount the display unit in a way that facilitates operation and where it is easy to see.

In order to raise the display, the display device can be mounted on an
optional stand.

6.6 Mains connection

Power is supplied via the external power supply unit.
Insert the mains plug into the wall socket.

Once connected, the instrument performs a self check. If the zero display
shows the device is ready for use.

6.7 Rechargeable battery operation (Factory option)

Charge the battery for at least 12 hours before initial use.
The battery symbol indicates the current charge level of the batteries. If the symbol

flashes, the capacity of the battery will soon be exhausted. The weighing scale
will remain ready for operation for a few more hours before switching off in order to
save battery. Fully charge the battery pack.

KXS/KXG-TM-BA_IA-e-1420 15

6.8 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate 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 weighing system 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 display unit periodically in weighing operation.

How to carry out adjustment:

 Unverified weighing systems, see chapter 11
 Verified weighing systems, see chapter 19.3

6.9 Verification

General introduction:

According to EU directive 90/384/EEC or 2009/23EG 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 notes:

An EU type approval exists for the appliance described in its technical data as
verifiable. If the appliance is used where obligation to verify exists as described
above, it must be verified and re-verified at regular intervals.
Re-verification of an appliance is carried out according to the respective national
regulations. Normally the validity for verification in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!

Verification of the device is invalid without the seals.

The seal marks / verification wire attached on verified appliances p oi nt out
that the appliance may only be opened and serviced by trained and
authorised specialist staff. If the sealing (paper seal/ verification wire) is
damaged, the verification validity expires. Please observe all national laws
and legal regulations. In Germany a re-verification will be necessary.

8 Applications:

8.1 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.

Determine the unit weight and count

1. In the weighing mode press the unit key, in order to activate the counting

function. The indicator Pcs is indicated.

2. Press the BG/NET-key repeatedly until the desired reference number of items

(e.g. 100) appears, select between C 10, C 20, C 50, C100, C 200.

3. Place as many items to be counted (such as 10 items) as demanded by the

set reference quantity and confirm by UNIT key. The weighing scales calculate

the reference weight. The current number of items (e.g. 10 pieces) is

indicated.

4. Remove reference weight. The balance is from now in parts counting mode

counting all units on the weighing plate.

KXS/KXG-TM-BA_IA-e-1420 21

Switch between number of items and weight

With the UNIT key you can switch between number of items and weight:

By switching the scale off and then on again the scale starts in the unit
counting mode. The current reference weight remains stored until the
reference is set again or the power supply is interrupted.

The counting function is not active, if the weight is under 20d or if below
the minimum piece weight (< 0.2 D) is reached.

Automatic reference o pt i miz at ion

In order to improve the counting exactness, the referenc e can be opt imised by
adding more pieces. At every reference optimisation, the reference weight is
calculated anew. As the additional pieces increase the base for the calculation, the
reference also becomes more exact.

 If the number of placed parts are 5 pieces more than the reference, then the

automatic reference optimisation starts. The reference weight is calculated anew.

18 Install a ti on display appliance/ load cell

Installation / configuration of the weighing system must be carried out by a
well acquainted specialist with the workings of weighing balances.

18.1 Weighing system design

The display unit is suitable for connection to any analogue platform in compliance
with the required specifications.
The following data must be established before selecting a weighing cell:

• Weighing balance capacity
This usually corresponds to the heaviest load to be weighed.

• Preload
This corresponds to the total weight of all parts that are to be placed on the
weighing cell such as upper part of platform, weighing pan etc.

• Total zero setting range
This is composed of the start-up zero setting range and the zero setting
range available to the user via the ZERO-key.
The addition of weighing scales capacity, preload and the total zero setting
range give the required capacity for the weighing cell.
To avoid overloading of the weighing cell, include an additional safety
margin.

• Smallest desired display division

• Verification ability, if necessary
