4 Basic Information (General)
Balances have to be verified for the purposes stated below in
accordance with Directive 2014/31/EU. Article 1, paragraph 4.
“Determination of mass in the practice of medicine that is, weighing
patients for reasons of medical supervision during medical
surveillance, examination and treatment.”
4.1 Specific function
4.1.1 Indication
•Determining the body weight in the medical practice area
•Using as „non-automatic balance“
➢The person steps carefully on the center of the weighing platform.
Once a steady display value is shown, you can read the weight result.
4.1.2 Contraindication
No contraindication known.
4.2 Proper use
This weighing scale is designed for determining the weight of a person whilst standing,
such as in medical treatment rooms. The regularly used function of the balance
consists of recognizing, prevention and treatment of illnesses.
•On personal weighing scales, the person should step onto the center of the
weighing platform and remain standing without moving.
Once a steady display value is shown, you can read the weight result. The weighing
scale is designed for continuous duty.
The weighing platform may only be stepped on by persons
capable of standing on both feet on the weighing platform.
•The weighing platforms are fitted with an anti-slip surface that must not be
covered during weighing a person.
•The balance should be checked for correct condition prior to each utilization by
a person familiar with proper operation of the balance.
•When using balances with mounted body height measuring rod, ensure that the
top flap is turned downwards immediately after use in order to avoid risk of
injury.
The WIFI interface allows a wireless transfer of the measurement results to a PC.
Scales fitted with a serial interface may only be connected to
appliances in compliance with Directive EN60601-1.

TMPN_A-BA-e-2213 17
If the balance doesn’t have any contact with the transfer cable,
do not touch the transfer port in order to avoid an ESD-failure.
4.3 Non-intended product use / contraindications
•Do not use these scales for dynamic weighing processes.
•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. This could cause
damage to the balance.
•Never operate the balance in explosive environment. The
serial version is not explosion protected. It should be noted
that a flammable mixture of anaesthetics and oxygen or
laughing gas may occur.
•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.
•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.
•The balance may only be used for weighing persons.
Persons who are heavier than the indicated maximum load,
may not step onto the balance.

18 TMPN_A-BA-e-2213
Non-intended use of the optional
body height measuring rod
•The body height measuring rod may only be assembled as
specified in the operating instructions.
•The structure of the body height measuring rod may not be
modified. This may result in incorrect measuring results,
safety-related defects as well as destruction.
•The body height measuring rod may only be used according
to the described conditions. Other areas of use must be
released by KERN in writing. For more details please see
the user manuals of the body height measuring rod.
4.4 Warranty
Warranty claims shall be voided in case:
•Our conditions in the operation manual are ignored
•The appliance is used beyond the described uses
•The appliance is modified or opened
•Mechanical damage and damage caused by media, liquids,
•Natural wear and tear
•Improper installation or faulty electrical connection
•The measuring system is overloaded
•Dropping the balance
4.5 Monitoring of Test Resources
In the framework of quality assurance the measuring-related weighing 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.
For personal balances with body height measuring rods, we recommend a metrological
examination of the accuracy of the body height measuring rod, however, this is not
mandatory as the determination of human body height involves rather large, intrinsic
inaccuracies.
4.6 Plausibility check
Please make sure that the measurement values computed by the appliance are
plausible and are allocated to the respective patient, before storing and using the
values for further purposes. This applies especially also for values transferred via
interface.

TMPN_A-BA-e-2213 19
4.7 Reporting serious incidents
All serious incidents appeared related to this product must be reported to the
manufacturer and the responsible authority of the member state where the user and/or
the patient are residents.
„Serious incident“ that means an incident which directly or indirectly had, could have
or could have had one of the following consequences:
➢the death of a patient, a user or another person,
➢the temporary or permanent fatal deterioration of the health status of a patient,
a user or other persons,
➢a serious danger for public health.

20 TMPN_A-BA-e-2213
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 medical staff must apply and follow the operating instructions for proper use and
care of the product.
The balance must be set up via the interfaces and integrated into a network only by
experienced administrators or hospital technicians.
5.3 Preventing contamination
The prevention of cross-contamination (fungal skin infections,……) requires regular
cleaning of the weighing platform. Recommendation: After any weighing procedure
that could potentially result in contamination (e. g. after weighing that involves direct
skin contact).
5.4 Preparation for use
•Check the personal balance for damage before any use
•Maintenance and reverification (in Germany MTK): The personal balance must
be serviced and reverified at regular intervals.
•Do not use the appliance on slippery surfaces or in facilities with risk of vibration
•During installation the personal balance must be levelled
•If possible, the product must remain in its original packaging for transportation
purpose. Should this not be possible, make sure that the product is protected
against damage
•Step onto and leave the personal balance only when a qualified person is
present
