3 Basic directions (general information)
According to the Directive 90/384/EEC 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
3.1.1Indication
- Determination of body weight in the course of medical practice.
- Used as a non-automatic scale i.e. a person is to be placed carefully in the centre 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. The weighing value can be read off after a stable weighing value has been
obtained.
3.1.2Contraindication
No contraindications.
3.2 Intended use
These scales are used to determine weight of people in standing and sitting position or
babies in lying position depending on the model in rooms intended for carrying out
medical care. 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 care-
fully in the centre of the scale plate and left at rest or in the case of chair scales, a per-
son should be seated in the centre of seat and left at rest.
In the case of wheelchair scales, place a wheelchair entirely on the platform and then
lock its wheels before carrying out weighing procedure.
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 se-
curely with both feet, or sit calmly (in the case of 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.

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.
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 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 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 weigh-
ing 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.

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 of 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 (pay attention to information label on the platform scales).
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 (Deutsche Kalibrierdienst) calibration laboratory (return to na-
tional 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 Operating Instructions
Please read these Operating Instructions carefully before erecting and commissioning
the balance, even if you already have experience with KERN medical scales.
4.2 Staff training
The device may only be operated and maintained by trained members of staff.
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 unpacking
for any visible signs of external damage.
5.2 Packaging / return transport
ÖKeep all parts of the original packaging for a possibly required re-
turn.
ÖOnly use original packaging for returning.
ÖPrior to dispatch disconnect all cables and remove loose/mobile
parts.
ÖReattach possibly supplied transport securing devices.
ÖSecure all parts such as the glass wind screen, the weighing plat-
form, 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 un-
der normal application conditions.
By selecting the correct location for your scale, you will be able to work quickly and pre-
cisely.
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 discon-
nected from mains supply;
•Avoid static charge build-up on 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 posi-
tion the scale in its intended working location. When the mains adapter is used, be care-
ful not to cause the danger of falling over the power cable.

6.2.1 Installation and Scale Setup

General direction concerning setting up the previously mentioned scales
Place a personal weighing scale in the intended location and level it with the adjustable
rubber feet until the air bubble in the spirit level (located in the centre of the scale plate)
is in the centre.
When scales with large and heavy platforms are installed and transported (a scale plate
folded upwards), take care not to drop a scale as this could cause its damage.
The following information label is located on the platform side.
Attention should be paid to lower the platform slowly on the floor and avoid
its falling down during this operation.
When the mains adapter is not used (and wall holder not installed), put the mains
adapter into the compartment located on the back wall of the operating panel to store it.
