3 Basic Information (General)
Weighing instruments have to be verified for the purposes stated
below in accordance with Directive 90/384/EEC. 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.”
Indication
Determining the body weight in the medical practice area.
Operated as “non-automatic weighing instrument” which
means that you have to carefully put he baby in the centre of
the weighing pan. Once a steady display value is shown, you
can read the weight value.
Contra-
indication
No contraindication known
Scales fitted with a serial interface may only be connected to
appliances in compliance with Directive EN60601-1.
To prevent babies lying on the weighing pan from falling off the
scale, they must be watched all the time. Please observe note
on weighing pan!
3.1 Specific function
3.2 Proper use
These scales serve as a means of determining the weight of babies in medical
treatment rooms. The scales are suitable for recognising, preventing and controlling
illnesses.
MBB-M-BA-e-1314 7
3.3 Improper Use
Do not use these scales for dynamic weighing processes.
Do not leave permanent load on the balance. This may damage the measuring
system.
-Impacts and overloading exceeding the stated maximum load (max) of the weighing
pan, 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. It should be noted that a flammable mixture of anesthetics 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.
3.4 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
3.5 Monitoring of Test Resources
In the framework of quality assurance the measuring-related weighing properties of
the balances 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 balances with height measuring rods, we recommend a metrological examination
of the accuracy of the height measuring rod, however, this is not mandatory as the
determination of human body height involves rather large, intrinsic inaccuracies.

4 Basic Safety Precautions
4.1 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.
4.2 Personnel training
The medical staff must apply and follow the operating instructions for proper use
and care of the product.
4.3 Preventing contamination
To prevent cross-contamination (fungal skin infections, …), clean the seating surface
or weighing platform every time.
Recommendation: after a weighing procedure that could potentially result in
contamination (e. g. after weighing that involves direct skin contact).
