4 Basic Information (General)
Weighing instruments have to be verified for the purposes stated
below in accordance with Directive 2009/23/EC.
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.”
4.1 Specific function
Indication

Determining the body weight in the medical practice area.
Use as „non-standalone weighing scale“, that is, a person
steps carefully onto the weighing platform‘s centre. Once a
steady display value is shown, you can read the weight value.
Contra-
indication

No contraindication known
4.2 Proper use
This weighing scale is designed for determining the weight of a person whilst
standing, such as in doctor’s surgeries. The balance is 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.
On personal weighing scales, the person should step onto the centre of the weighing
platform and remain standing without moving.
As soon as a stable weighing value is reached the weighing value can be read.
The weighing scale is designed for continuous duty.
The weighing platform may only be stepped on by persons
capable of standing on both feet on the weighing platform.
The weighing platforms are fitted with an anti-slip surface that must not be covered
during weighing a person.
The balance should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.

4.3 Improper Use
Do not use these scales for dynamic weighing processes.
Do not leave permanent load on the weighing pan. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of 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.
The structure of the balance may not be modified. This may lead to incorrect
weighing results, safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
4.4 Warranty
Warranty claims shall be voided in case
•Our conditions in the operation manual are ignored
•The appliance is used outside the described uses
•The appliance is modified or opened
•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 the balance
4.5 Monitoring of Test Resources
In the framework of quality assurance the measuring-related weighing properties of
the balance 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.

5 Basic Safety Precautions
5.1 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.
All language versions contain a non-binding
translation. The original German is binding.
5.2 Personnel training
The medical staff must apply and follow the operating instructions for proper use and
care of the product.
5.3 Preventing contamination
The prevention of cross-contamination (fungal skin infections,……) requires regular
cleaning of the weighing platform. Recommendation: after a weighing procedure that
could potentially result in contamination (e. g. after weighing that involves direct skin
contact).

6 Electromagnetic compatibility (EMC)
6.1 General hints
The installation and use of this electrical medical device requires
special precautionary measures as outlined in the EMC information
below.
This device complies with the limits set for medical electrical devices of group 1,
class B (as per EN 60601-1-2).
Electromagnetic compatibility (EMC) describes a device’s ability to perform reliably
within an electromagnetic environment without causing inadmissible electromagnetic
interference at the same time. Amongst other things, such disturbances may be
emitted by connecting cables or the air.
Inadmissible disturbances from the environment may result in incorrect displays,
inaccurate measured values or incorrect behaviour of the medical device. By the
same token the medical device may in some cases cause such disturbances in other
devices. To eliminate problems of that kind, we recommend you to take one or
several of the measures listed below:
•Change the alignment or distance of the device to the source of EMI.
•Install or use the personal scale MPD-M at a different location.
•Connect the personal scale MPD-M to a different power source.
•For further questions please contact our customer services.
Disturbances may be caused by improper modification or add-ons to the device or
not recommended accessories (such as power units or connecting cables). The
manufacturer will not be responsible for these. Modifications may also result in a loss
of authorisation relating to the use of the device.
Devices emitting high frequency signals (mobile telephones, radio
transmitters, radio receivers) may cause interference in the medical
device. For that reason do not use them near the medical device.
Chapter 6.4 contains details about recommended minimum distances.
