3 Basic instructions
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 not intended for use as
non-automatic weighing system.
Place load manually but carefully on weighing platform.
Prevent loads from dropping.
Place load in centre.
Prevent lateral stress as well as pushing from the side.
As soon as a stable weighing value is reached the weighing value can be
read.
20 KEN-TM / KET_TM-BA-e-1420
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 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 weighing
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 faults and destruction 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
3.4 Monitoring of Test Resources
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

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.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and 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 against shifting and damage.

Operating and Installation Instructions
6 Unpacking, Setup and Commissioning
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 installation site observe 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 draft from open
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 display unit in a way that facilitates operation
and where it is easy to see.
The display unit is not mounted rigidly on the weighing platform. If
required, it may be placed independently within the vicinity of the weighing
scale as long as the length of the cable allows such a setup.
6.3 Scope of delivery / serial accessories
KEN-TM / KET_TM-BA-e-1420 23
6.4 How to connect the platform
See chap. 21 “Installing display unit / platform“.
Please also follow the instructions for installing a platform, as these contain all the
details for the set-up and first start-up.
6.5 Mains connection
Power supply is achieved via external power units (KET-TM only). 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.
6.6 Commissioning
+ Connect scale to power supply.
Connect display unit to power supply; the red status light will light up.
Press and the operating system will be loaded when the red status light is
flashing.
Wait until the start screen followed by the user interface is displayed.
As soon as the weight display appears, the balance is ready for weighing. On
delivery, the weighing scale will be in a logged-out status, that is, merely the
simplest functions such as Weigh or Tare are enabled, see chap. 6.9.
To obtain full access to the user parameters and to the editing functions of
databases, the user has to log on as administrator by following the steps below:

For data format see chap. 16.4
6.9.2 Zeroing
In order to obtain optimal weighing results, reset to zero the balance before weighing.
Setting to zero requires a range ± 2% max. Values greater than ± 2% max will trigger
the error message “Err2“.
Unload the balance
Press and zero display as well as indicator will appear.
