2 Declaration of conformity
To view the current EC/EU Declaration of Conformity go to:
www.kern-sohn.com/ce
3 Basic directions (general information)
3.1 Intended use
The scales are used for determining the body weight of people in the standing posi-
tion.
The person being weighed shall stand in the middle of the weighing surface and re-
main calm.
The value may be read after the scales stabilizes.
The scales are designed for continuous use.
Only those people who can stand on the scales platform with their
both legs may enter it.
The scales platform is equipped in the anti-slippery surface which shall not be taken
off or covered during the time the people are being weighed.

MPS / MTS / MXS / MWS-BAPS-e-1710
10
3.2 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 are-
as of application/planned use must be approved by KERN in writing.
Do not use the scales for determining body weight in medicine.
3.3 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.

MPS / MTS / MXS / MWS-BAPS-e-1710

3.4 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 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 commissioning, even if you are al-
ready familiar with KERN balances.

MPS / MTS / MXS / MWS-BAPS-e-1710

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 po-
sition 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.
