6 Basic Information (General)
Weighing instruments have to be verified for the purposes stated
below in accordance with Directive 2014/31/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.”
6.1 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

MPE_HM / MPE_PM-BA-e-2255 15
6.2 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.
When using balance with body height measuring rod, ensure that the top flap is
turned downwards immediately after use in order to avoid risk of injury.
If the balance doesn’t have any contact with the transfer cable,
do not touch the transfer port in order to avoid an ESD-failure.

16 MPE_HM / MPE_PM-BA-e-2255
6.3 Non-intended product use / contraindications
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 overload 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.
If the balance is not used for a longer time, take out the batteries
and store them separately. Leaking battery liquid could damage
the balance.
Improper use of the optional height meter
The height meter may only be assembled such as described in
the operating instructions. The structure of the body height
measuring rod may not be modified. This may cause incorrect
measurement results, safety-related faults as well as destruction.
The height meter may only be used according to the defined
specifications. Other areas of use must be released by KERN in
writing.

MPE_HM / MPE_PM-BA-e-2255 17
6.4 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
6.5 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.
Using measuring technology to check the accuracy of the measuring device is
recommended for personal floor scales with body height measurement but is not
absolutely essential as the calculation of the human body height is always subject to
a great deal of inaccuracy.

18 MPE_HM / MPE_PM-BA-e-2255
6.6 Plausibility check
Please make sure that the measurement values computed by the appliance are
plausible and are allocated to the respective patient, before storing and using the
values for further purposes. This applies especially also for values transferred via
interface.
6.7 Report of serious incidents
All serious incidents appeared related to this product must be reported to the
manufacturer and the responsible authority of the member state where the user
and/or the patient are residents.
„Serious incident“ that means an incident which directly or indirectly had, could have
or could have had one of the following consequences:
the death of a patient, a user or another person,
the temporary or permanent fatal deterioration of the health status of a patient,
a user or other persons,
a serious danger for public health,

MPE_HM / MPE_PM-BA-e-2255 19
7 Basic Safety Precautions
7.1 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.
7.2 Personnel training
The medical staff must apply and follow the operating instructions for proper use and
care of the product.
7.3 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).
7.4 Preparation for use
•Check the personal balance for damage before any use
•Maintenance and re-verification (in Germany MTK)
The personal balance must undergo maintenance and re-verification at regular
intervals.
•Do not use the appliance on slippery surfaces or in rooms with risk of vibration
•During installation the personal balance must be levelled.
•If possible, the product must remain in its original packaging during the
transport. Should this not be possible, make sure that the product is protected
against damage.
•Step onto and leave the personal balance only when a qualified person is
present

8 Electromagnetic compatibility (EMC)
8.1 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 floor scales MPE at a different location.
•Connect the floor scales MPE 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 floor scale
MPE. For that reason do not use them near the floor scale MPE.
Chapter 8.4 contains details about recommended minimum distances.
