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.
The weighing process requires that the person stands on the weighing plate in a way
that provides even weight distribution over the entire weighing plate. As soon as a
stable weighing value is reached the weighing value can be read.
2.2 Improper Use
Do not use balance for dynamic weighings. The removal or addition of small amounts
of load may result in the display of inaccurate weighing results! (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.
Take care to avoid impacts and overloading of balance above the specified maximum
load (max) under all circumstances. This could cause damage 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
weighing 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

3 Basic Safety Precautions
3.1 Pay attention to the instructions in the Operation Manual
Caution: There is a danger of slipping when stepping on the glass weighing plate.
If required, stick the self-adhesive rubber strips included in the delivery to the
weighing plate.
Stepping on the edge of the weighing plate may cause tilting of balance or fall of
person.
Carefully read this operation manual before setup and commissioning, even if you
are already familiar with KERN balances.
4 Transportation & Storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance 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.
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, vapours 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 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
Take the whole balance out of their packaging and place them at the intended
position.
In addition to the balance, delivery also includes the operating instructions and a
battery.
5.3 Battery operation (insertion and removal)
To insert your battery, open the battery compartment at the rear of the balance (by
unscrewing the cover with the help of a coin) and insert a 3V lithium battery ( CR2032
) in the correct direction of the pole, then close the battery compartment. (Put on
cover and turn it in reverse direction of the arrow until the cover locks)
If the balance is not used for a longer time, take out the batteries and store them
separately. Leaking battery liquid could damage the balance.
In as-delivered condition a paper strip is inserted under the battery contact in order to
prevent switching on during transport. You will have to remove this strip before initial
use by removing the inserted battery.
6 Using the balance
You can change the balance’ weighing unit from “kg“ to “lb“ at the rear of the
balance.
To turn on the balance, tap the glass plate briefly with your foot.
The display briefly shows " - - - - " several times, followed by 0.0 kg and 0.0 lb
respectively.
The weighing process requires that the person stands on the weighing plate in a way
that provides even weight distribution over the entire weighing plate.
„ - - - - “ flashes several times on the display.
After reaching a stable weighing value, the latter will be displayed and can be read.
After determining the weighing value, the latter will be visible on the display for
another 6 seconds before the balance switch off automatically.
Notice: The typical weight of a person will vary over the day, and equally from one
day to the next. Minor weight variations are considered normal.
