2 Basic Information (General)
2.1 Proper use
These balance is used to calculate the weight of people in the private sphere.
Utilisation of this balance in the medical field is not permissible.
A person must stand on the weighing plate for the weighing procedure. As soon as a
stable weighing value is reached the weighing value can be read.
When using balance with height measurement, ensure that the top flap is turned
downwards immediately after use in order to avoid risk of injury.
The balance should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.
2.2 Improper Use
Do not use balance for dynamic weighings. In the event that small quantities are re-
moved or added to the material to be weighed, incorrect weighing results can be dis-
played due to the “stability compensation“ in the balance. (Example: Slowly draining
fluids from a container on the balance. )
Do not leave permanent load on the weighing plate. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the balance,
minus a possibly existing tare load, must be strictly avoided. This could cause dam-
age to the balance.
Never operate balance in explosive environment. The serial version is not explosion
protected.
The structure of the balance may not be modified. This may lead to incorrect weigh-
ing results, safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
2.3 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 and damage caused by media, liquids
natural wear and tear
The appliance is improperly set up or incorrectly electrically connected
The measuring system is overloaded

2.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the bal-
ance and, if applicable, the testing weight, must be checked regularly. The responsi-
ble user must define a suitable interval as well as type and scope of this test. Infor-
mation is available on KERN’s home page (www.kern-sohn.com) with regard to the
monitoring of balance test substances and the test weights required for this. In
KERN’s accredited DKD calibration laboratory test weights and balances may be
calibrated (return to the national standard) fast and at moderate cost.
Using measuring technology to check the accuracy of the measuring device is rec-
ommended for personal balances with body height measurement but is not abso-
lutely essential as the calculation of the human body height is always subject to a
great deal of inaccuracy.

3 Basic Safety Precautions
3.1 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.
3.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
4 Transportation & Storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appli-
ance itself when unpacking for possible visible damage.
4.2 Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts e.g. weighing platform,
power pack, stand, operating panel etc. against slipping and damage.

5 Unpacking, Setup and Commissioning
5.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
- Place the balance 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 balance against direct draughts due to open windows and doors;
- Avoid jarring during weighing;
- Protect the balance against high humidity, vapors and dust;
- Do not expose the device 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 the balance and of the person to be weighed.
- Avoid contact with water.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.

5.2 Unpacking
Remove the individual components of the balance or the complete balance from the
packaging with care and install at the intended location. When using the power pack,
ensure that the power cable does not produce a risk of stumbling.
