Product specifications (from provided source text)

Setup and use

1. Select the place of use: choose a location meeting the environment requirements and stable operating conditions.
2. Prepare installation: bring the device and the required scope-of-delivery parts/tools/documentation to the place of use.
3. Remove transport safety lock: do not remove screws other than those of the transport safety lock. Remove the transport safety lock according to the model’s lock type. Ensure corner load stops are not removed (where applicable).
4. Install weighing plate and level the device: position and level the scale by adjusting the levelling feet until the level indicator’s air bubble is within the specified circle.
5. Choose power method:
   • Mains operation: (a) fit the correct power plug adapter if provided, (b) connect the mains cable to the device, then insert the plug into the socket.
   • Rechargeable battery pack (factory option): charge the battery before first use by connecting the power supply/charger to the scale.
6. Commissioning: allow the scale to reach operating temperature; during acclimatisation, keep the scale connected to the power supply.
7. Open setup menu: in operating mode, press and hold [TARE] and [ON/OFF] simultaneously until the setup menu is shown.
8. Run adjustment (from the setup menu): ensure the weighing plate is free of any load, confirm, place the adjustment weight centrally, confirm, remove the adjustment weight; if an adjustment error occurs, restart and repeat.
9. Return to operating mode: after successful adjustment the scale switches to operating mode.

Intended use of the scale
Improper use of the scale
2.4 Notes on IT security
This device is equipped with an interface for data transmission.
Unauthorised persons may be able to gain access to the
data being exchanged. It is the operator’s responsibility to
identify the potential IT risks at the place of use and to take
appropriate countermeasures where necessary.
2.5 Intended use
This scale is used to determine the weight of items to
be weighed. This scale is a “non-automatic weighing instrument”.
This means that the material to be weighed must be
placed manually, with care and as centred as possible on the
weighing plate. Once a stable weight value is displayed, the
result can be read.
2.6 Improper use
■ Our scales with strain gauges are not intended for use in
dynamic weighing processes.
However, the scales can also be used for dosing applications
after checking the individual area of application and
the accuracy requirements.
You can find out whether your scale is equipped with
strain gauge technology by checking the technical data.
⮫ Chapter 18.1 ‘Technical data’ on page 92
■ To prevent damage, avoid impact loadings and do not
exceed the maximum load limit (Max.) of the scale.
■ Any modification to the design of the scale will invalidate
the warranty and may lead to incorrect weighing results
and safety-related defects. Such modifications are therefore
prohibited.
■ The scale may only be used in accordance with the specifications
described in this document.
■ The scale is not designed for weighing people. It is not
suitable for medical purposes.
2.7 Obligations of the operating company
It is the responsibility of the operating company to comply
with the specifications described in this document as well
as with legal and official regulations at the place of use.
Any failure to comply with the safety precautions and instrucGeneral
safety instructions
TDS-A_TDS-B-BA-e-2620 15
tions described in this document is considered improper use.
KERN & SOHN is not liable for any damage resulting from
improper use.
2.8 Required user qualifications
■ Assembly, commissioning, servicing and maintenance of
the device may only be carried out by qualified personnel.
A qualified person is a person with appropriate professional
training or qualifications for the activities described.
They have in-depth knowledge of the tasks and the relevant
safety standards.
■ Only trained users may operate, handle and maintain the
device. A trained user is a person who has been trained
in the use of the device and in the corresponding safety
instructions.
2.9 Requirements for the environment of use
In addition to the environmental information in the technical
data, observe the following requirements for the environment
of use:
■ The device must not be operated in environments where
there is a risk of corrosion.
■ The device must be protected from excessive humidity,
steam, spray and dust.
■ The device must be protected from excessive moisture
caused by condensation. Condensation can occur if the
device is moved from a cold environment to a much
warmer environment. If such a change of environment
cannot be avoided, allow the device to acclimatise for
approx. 2 hours before starting it up.
■ The device must not be used in environments with aggressive
chemicals, gases or liquids.
■ The device must not be used in potentially explosive
atmospheres or environments where explosives are
present.
■ The device must not be used in environments subject to
severe impacts or vibrations.
■ The device must not be exposed to extreme heat or strong
temperature fluctuations (e.g. by placing the device next
to a heater or in direct sunlight).
■ Protect the device from direct draughts.
General safety instructions
16 TDS-A_TDS-B-BA-e-2620

6.3 Adjustment settings
The acceleration due to gravity varies at different locations
on earth. For exact weighing results, the scale must be
adjusted to the prevailing acceleration due to gravity at the
location where it is installed. The scale must have reached its
operating temperature before it can be adjusted.
Adjustment of the scale is required in the following cases:
■ Before initial commissioning, if the scale has not already
been adjusted to the installation location at the factory.
■ After every change of location.
■ After a significant change in environmental conditions (e.g.
temperature or humidity).
■ If the scale has been disconnected from the power supply.
To ensure accurate measurements, it is also recommended
that the scale is adjusted regularly.
NOTICE
Incorrect weighing results
− Avoid unstable environmental conditions
during adjustment (e.g. vibrations or air
draught).
− Ensure that the scale has reached its operating
temperature. ⮫ Chapter 18.1 ‘Technical
data’ on page 92
− Only carry out the adjusting procedure with
the standard weighing plate in place.
− During external adjusting, ensure that only the
adjustment weight is on the weighing plate
without any other load.
− Only handle adjustment weights with
tweezers, weight handles or gloves. Avoid
direct skin contact between your hands and
adjustment weights.

7.1 Optional software
BalanceConnection enables communication between scales
and peripheral devices. This software supports various interfaces
and protocols to ensure flexible integration into existing
systems. It is particularly useful for applications where centralised
collection and processing of measurement data is
required.
With EasyTouch, your weighing data is sent directly to your
PC, laptop or tablet for immediate further processing. Easy-
Touch also allows you to add other useful functions to your
scale and tailor it perfectly to your specific field of application.
For further information about KERN software, please visit our
website at ⮫ www.kern-sohn.com.

Weighing application
62 TDS-A_TDS-B-BA-e-2620
CAUTION
Risk of breakage due to overloading of the
hook
Falling loads may cause injury.
− Never exceed the scale’s specified maximum
load (Max.).
− Make sure there are no living creatures or
objects under the load that could be damaged.
NOTICE
Damage to the scale caused by dirt getting
inside
Dirt (e.g. dust) entering the measuring system
can cause damage and lead to incorrect results.
− Close the opening for the weigh-below hook
once underfloor weighing is complete (to prevent
dust ingress).
1. Switch off the scale.
2. Turn the scale over.
3. Open the cover on the bottom side of the scale.
⮫ Chapter 3.2 ‘Overview of the device’ on page 17
