4 Basic Information (General)
4.1 Intended use
These balances serve as a means of determining the weight of babies in medical
treatment rooms (hospitals or Doctor practices). The frequently used function of the
baby scale is recognising, preventing and controlling illnesses.
The WIFI interface allows the measured results to be transmitted wirelessly to a PC.
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!

TMBA_B-BAPS-e-2010 11
4.2 Improper 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 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 scale is for weighing baby only. Any person with weight over
15 kg, do not step on the scale.
Improper use of optional height meter MBA-A01:
The structure of the height measuring rod may not be modified.
This may result in incorrect measuring results, safety-related
defects as well as destruction.
The height
measuring rod may only be used according to the
described conditions. Other areas of use must be released by
KERN in writing. More details in the instruction manuals of the
height meter.
4.3 Warranty
Warranty claims shall be voided in case of
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

12 TMBA_B-BAPS-e-2010
4.4 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 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.

TMBA_B-BAPS-e-2010 13
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 Preparing for use
•Check the balance for damage before any use
•Maintenance and re-verification
The baby scale must be serviced and re-verified at regular intervals. (see
chapter 12.4)
•Do not use the device on slippery surfaces or in rooms susceptible to
vibrations
•The balance must be levelled during installation
•If possible, the product must be transported in its original packaging when
transporting. If this is not possible, ensure that the product is protected from
damage.

6 Transport and storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
6.2 Packaging / return transport
Keep all parts of the original packaging for a possibly required
return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove loose/mobile
parts.
Reattach possibly supplied transport securing devices.

7 Unpacking, Setup and Commissioning
7.1 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.
On the installation site observe the following:
Place scales on a stable, even 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 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.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. In that case, the location
must be changed.
7.2 Unpacking
Take the balance out of their packaging and place it at the intended position. When
using the power pack, ensure that the power cable does not produce a risk of
stumbling.
7.3 Scope of delivery

7.6 Mains connection (option)
Power is supplied by the external power unit which also serves to isolate the mains
supply from the scale. The stated voltage value must be the same as the local
voltage.
Only approved genuine KERN power supply units may be used in compliance with
Directive EN 60601-1.
7.7 Optional equipment mains adapters
Available mains adapters (optional)
•YKA-43
•YKA-44
7.8 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap.1). During this
warming up time the balance must be connected to the power supply (mains,
accumulator or battery) and be switched on.
The accuracy of the balance depends on the local acceleration of gravity.
The value of gravity acceleration is shown on the type plate.
