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 (return to the national standard) fast and at moderate cost.

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.

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.

The automatic zero point adapter (auto zero) provides continuous correction for minor weight variations such as contamination on the weighing platform. 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“. (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.

7.9 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.
The adjustment of this menu item is locked in calibrated weighing systems. It is not shown on the menu.
To disable the access lock, destroy the seal and actuate the service switch. For position of service switch see chap. 7.10.
Attention: After destruction of the seal the weighing system must be re-verified by an authorised agency and a new verification wire/seal mark fitted before it can
+ For execution of “adjust weighing system“ see chap. 21.4
7.10 Verification
General introduction:
According to EU directive 2009/23/EC 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 purpose. d) For manufacturing final packages.
In cases of doubt, please contact your local trade in standard.
Verification notes:
An EU Qualification Approval is in existence for verified weighing systems. If a balance is used where obligation to verify exists as described above, it must be verified and re­verified at regular intervals. Reverification is carried out according to the relevant national statutory 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!
