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.”
3.1 Specific function
Indication
Determining the body weight in the medical practice area.
To be used as “non-automatic weighing instruments“, that is,
a person will step or sit down carefully onto the centre of the
seating surface or weighing platform. The weighing value can
be read after a steady display value has been achieved.
Contra-
No contraindication known.
indication
3.2 Proper use
These scales serve as a means of determining the weight of people in a seated or
standing position, in medical treatment rooms. The scales are suitable for
recognising, preventing and controlling illnesses.
Scales fitted with a serial interface may only be connected to
appliances in compliance with Directive EN60601-1.
The person to be weighed should be seated in the centre of the seating surface or
step onto the weighing platform and sit or stand still.
As soon as a stable weighing value is reached the weighing value can be read.
The scales are designed for long-term usage.
Scales may only be used for people who are able to sit or stand
still.
The balances should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.
MCB_MPT-BA-e-1217 7



The chair scales may not be used for the transport of people!
As long as the patient is remaining on the chair scales, the
wheel brakes must be locked without fail.
Do not step onto the foot rests when stepping or leaving the
chair scales!
3.3 Improper Use
Do not use these scales for dynamic weighing processes.
Do not leave continuous loads on the seating surface or weighing plate. This may
damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the seating
surface or 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.
Do not modify the construction of the scales. This may lead to incorrect weighing
results, safety-related faults and destruction of the balances.
The balances 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
Modification or opening of appliances
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 of scales
8 MCB_MPT-BA-e-1217

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.

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.
Versions in other languages are non-binding translations.
The only binding version is the original document in German.
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).

8 Transportation & Storage
8.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
8.2 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.
Secure all parts such as the weighing platform, power unit etc.
against shifting and damage.
MCB_MPT-BA-e-1217 15

9 Unpacking, Setup and Commissioning
9.1 Place of installation / place of operation
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, 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.
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.
9.2 Unpacking
Remove the individual components of the balance or the complete balance from the
packaging with care and install at the intended location. When using the power pack,
ensure that the power cable does not produce a risk of stumbling.
9.3 Scope of delivery chair scales

9.4 Installing the chair scales
In delivery state the balance is adjusted in a manner that when placed on an
even surface the air bubble of the water balance is in the prescribed circle.
To check place scales on an even surface.
Check if the air bubble of the level is within the prescribed circle.
If the air bubble in the level is not within the prescribed circle, the
wheel height has to be adjusted, see chap. 9.4.1.
Check levelling regularly.
MCB_MPT-BA-e-1217 17

9.4.1 Levelliing
