3 Basic Information (General)

Intended use

These balance is used to calculate the weight of people

standing upright in the private sphere. Utilisation of this

balance in the medical field is not permissible.

The person must step on the weighing plate for the weighing

procedure. As soon as a stable weighing value is reached the

weighing value can be read.

Non-intended

use

Do not use balance 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 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 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.

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

Dropping the balance

Test device

control In the framework of quality assurance the measuring-related

properties of the balance 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 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.

4 Basic Safety Precautions

Carefully read this operation manual before setup and

commissioning, even if you are already familiar with KERN

balances.

5 Transportation & Storage

Testing upon

acceptance When receiving the appliance, please check packaging

immediately, and the appliance itself when unpacking for

possible visible damage.

Packing/

Return

transport

ÖKeep all parts of the original packaging for a possibly

required return.

ÖOnly use original packaging for returning.

ÖPrior to dispatch disconnect all cables and remove

loose/mobile parts.

ÖSecure all parts e.g. powerpack against slipping and

damage

Installation

location,

Deployment

location

The balance is 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.

On the installation site observe the following:

Place scales on a stable, even surface

Maintain a gap of 30 cm on all sides away from walls and

other objects or obstacles.

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.

Unpacking Remove the individual components of the balance or the

complete balance from the packaging with care and install at

the intended location.
