4 Basic Information (General)
4.1 Proper use
The digital weighing transmitter acquired by you is used in combination with a
platform 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.
4.2 Improper Use
Do not use weighing system (YKV and platform) 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 device.
(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. The weighing
system could be damaged.
Never operate the weighing system in explosive environment. The serial version is
not explosion protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the weighing
system.
The weighing system may only be operated in accordance with the described default
settings. Other areas of use must be released by KERN in writing.
4.3 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

4.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
weighing system 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 digital
weighing platforms may be calibrated (return to the national standard) fast and at
moderate cost.
5 Basic Safety Precautions
5.1 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.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
6 Transport and storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
6.2 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.

7 Unpacking and placing
7.1 Installation Site, Location of Use
The weighing system is designed to achieve reliable weighing results under normal
conditions of use.
You will work accurately and fast, if you select the right location for your weighing
system.
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 weighing system against direct draughts due to open windows and
doors;
•Avoid jarring during weighing;
•Protect the weighing system against high air humidity, vapours and dust;
•Do not expose the weighing system 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 weighed items 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.
7.2 Unpacking and checking
Take the weighing transmitter out of the packaging, remove the packaging material
and install at the designated workstation. Check if that there has been no damage
and that all packing items are present.
Scope of delivery / serial accessories:
•Weighing transmitter
•Net adapter EU/UK/US
•USB A to USB B cable
•These installation instructions
•Software KERN BalanceConnection

7.3 Transport Securing
Please note: if the YKV is used together with platform with transportation lock, this
transportation lock must be released prior to use.

7.4 Installation Weighing transmitter - Platform
Installation / configuration of a weighing system must be carried out by a well
acquainted specialist with the workings of weighing balances.
7.4.1 Weighing system design
The digital weighing transmitter is suitable for connection to any analogue load cell in
compliance with the required specifications.
The following data must be established before selecting a load 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 (± 2%) and the zero
setting range available to the user via the ZERO-function (2%). The total
zero setting range equals therefore 4 % of the scale’s capacity.
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.
