3 Basic directions (general information)
According to the Directive 2009/23/EC scales must be verified to the following application purposes. Article 1, paragraph 4 „Determination of
weight in the course of medical practice i.e. weighing of patients for the
purpose of health monitoring, diagnosis and medical treatment.”
3.1 Use
3.1.1 Indication
- Determination of body weight in the course of medical practice.
- Used as a „non-automatic scale” i.e. a person
• is placed carefully on the centre of the weighing plate or on a suspended balance in a suitable holding device.
• in a baby scales the baby must also be put or set on the weighing pan.
• For wheel chair scales, a wheel chair together with the person sitting in it is
pushed over the ramp into the centre of the weighing plate and/or the electric
wheel chair is moved automatically driven onto the weighing plate.
• When weighing with transportation stretchers, the person is placed with the
transportation stretcher centrically on the weighing plate.
After reaching a stable display value, the weight value can be read off.
3.1.2 Contraindication
No contraindications.
MPS / MTS / MXS / MWS-BA-e-1417 8
3.2 Intended use
Depending on the model, the scale is used to determine the weight of standing persons, sitting persons and persons lying on a transportation stretcher and the weight
of lying babies in medical treatment rooms, as per model. The balance is suitable for
recognising, preventing and controlling illnesses.
The scales equipped with serial interface can only be connected to the
equipment compliant with EN60601-1 standard.
• On personal weighing scales, the person should step onto the centre of the
weighing platform and remain standing without moving, or on chair scales sit
in the centre of the seating surface and remain seated quietly.
• The whole wheel chair is to be pushed onto the weighing plate and/or the
electric wheel chair is to be moved automatically onto the weighing plate and
the wheels have to be fixed for weighing.
• When persons are weighed on the transportation stretcher, the whole transportation stretcher must be pushed on the centre of the weighing plate and the
wheels have to be fixed for weighing.
As soon as a stable weighing value is reached the weighing value can be read.
The weighing scale is designed for continuous duty.
MPS / MTS / MXS / MWS-BA-e-1417 9
The scale platform can only be walked on by people that can stand on it
securely with both feet, or sit calmly (in the case of chair scale and wheel
chair scale).
Scale platforms or footrests are equipped with anti-slip material which cannot be
removed or covered when people are weighed.
When scales equipped with height measure are used, pay attention that the top flap
is always folded down after their use to avoid danger of injury.
Before any use, the scale must be checked for correct condition by an authorised
person.
When the scale doesn’t connect with the transmission cable,
please do not touch the transmission port to prevent ESD interference occurs.
3.3 Inappropriate use
Do not use the scales for dynamic weighing.
Do not leave a permanent load on the weighing plate. This can damage the measuring equipment.
Be sure to avoid impact shock and overloading the scale in excess of the prescribed
maximum load rating (max.), minus any possible tare weight that is already present.
This could result in damage of the scale.
Never operate the scale in hazardous locations. The series design is not explosionproof. Attention should be paid that flammable mixture may also be formed from
anaesthesiological means that contain oxygen or laughing gas (nitrous oxide).
Construction alterations may not be made to the scale. This can lead to incorrect
weighing results, faults concerning safety regulations as well as to destruction of the
scale.
The scale may only be used in compliance with the described guidelines. Other areas of application/planned use must be approved by KERN in writing.
MPS / MTS / MXS / MWS-BA-e-1417 10
3.4 Guarantee
The guarantee shall become void in the event of the following:
• non-observation of our guidelines in the Operating Instructions,
• use outside the described applications,
• alteration to or opening the device,
• mechanical damage or damage caused by media, liquids,
• usual wear and tear,
• inappropriate erection or electric installation,
• overloading of the measuring equipment,
• scale falling down.
3.5 Monitoring the test substances
The metrology features of the balance and any possible available adjusting weight
must be checked at regular intervals within the scope of quality assurance. For this
purpose, the responsible user must define a suitable interval as well as the nature
and scope of this check. 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. Test weights and balances can be adjusted quickly and at a
reasonable price at KERN’s accredited DKD (Deutscher Kalibrierdienst) calibration
laboratory (return to national standard).
In the case of the scales for weighing people provided with the scale to determine a
body size, it is recommended to carry out the check of its measuring accuracy because determination of the human body size is always connected with a very large
inaccuracy.

4 Basic safety directions
4.1 Observing the directions included in the Ope r ating Instructions
Carefully read this operation manual before
setup and commissioning, even if you are already familiar with KERN balances.
All language versions contain a non-binding
4.2 Personnel training
The medical staff must apply and follow the operating instructions for proper use and
care of the product.
4.3 Avoidance of contamination
To avoid cross contamination (mycosis, ...), the scale plate is to be cleaned regularly.
Recommendation: after each weighing which could result in potential contamination
(e.g. when there is a direct skin contact during weighing).

NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption

6 Transport and storage
6.1 Check upon delivery
Please check the packaging immediately upon delivery and the device during unpacking for any visible signs of external 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.
Secure all parts such as the weighing platform, power unit
etc. against shifting and damage.

7 Unpacking, installation and starting
7.1 Place of installation, place of use
The scale is designed in such a way that reliable weighing results can be achieved
under normal application conditions.
By selecting the correct location for your scale, you will be able to work quickly and
precisely.
Therefore, please observe the following when choosing a place of installation:
- Place the scale on a firm, level surface;
- Avoid extreme heat as well as temperature fluctuation caused by installing the
scale next to a radiator or in the direct sunlight;
- Protect the scale against direct draughts due to open windows and doors;
- Avoid shaking during weighing;
- Protect the scale against high humidity, vapours and dust;
- Do not expose the device to extreme dampness for longer periods of time. In-
admissible bedewing (condensation of air moisture on the device) can occur if
a cold device is taken into a significantly warmer environment. In this case,
please keep the device for approx. 2 hours at room temperature after it has
been disconnected from mains supply;
- Avoid static charge build-up on the scale and people to be weighed;
- Avoid contact with water.
Major display deviations (incorrect weighing results) are possible if electromagnetic
fields occur (e.g. coming from mobile phones or radio equipment) as well as due to
static charging and instable power supply. It is necessary then to change the scale
location or remove disturbance source.
7.2 Unpacking
Carefully remove individual scale parts or the whole scale from its packaging and
position the scale in its intended working location. When the mains adapter is used,
be careful not to cause the danger of falling over the power cable.
