of the scale plate or in the suitable supporting device in the case of wheelchair or
chair scales. In the case of baby scales, a baby is to be always laid down or seated
on the scale pan. For wheel chair scales, a wheel chair together with the person sit-
ting in it is pushed over the ramp into the center of the weighing plate and/or the
electric wheel chair is moved electrically driven onto the weighing plate.
The weighing value can be read off after a stable weighing value has been obtained.
3.1.2Contraindication
No contraindications.
3.2 Intended use
Depending on the model, the scale is used to determine the weight of standing per-
sons, sitting persons and/or persons sitting in the wheel chair at a wheel chair scale
and the weight of lying babies in medical treatment rooms The scales are intended to
diagnose, prevent and monitor diseases.
The scales equipped with serial interface can only be connected to the
equipment compliant with EN60601-1 standard.
In the case of personal weighing scales, a person to be weighed is to be placed
carefully in the centre of the scale plate and left at rest or in the case of chair scales,
a person is to be sat in the centre of seat and left at rest.
The whole wheel chair is to be pushed onto the weighing plate and/or the electric
wheel chair is moved onto the weighing plate and the wheels have to be fixed for
weighing.
The weighing value can be read off after a stable weighing value has been obtained.
The scale is designed for continuous operation.
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.
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 measur-
ing 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 explosion-
proof. 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 ar-
eas of application/planned use must be approved by KERN in writing.
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

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 be-
cause 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 Operating Instructions
Carefully read this operation manual before setup and commission-
ing, 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 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).
5 Transport and storage
5.1 Check upon delivery
Please check the packaging immediately upon delivery and the device during un-
packing for any visible signs of external damage.
5.2 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.

6 Unpacking, installation and starting
6.1 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.
6.2 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.
