indication
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.
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.
14 MPC_M / MPE_HM / MPE_PM-BA-e-1414
6.3 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 f ault s and des tr uct ion 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.
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 fl oor scal es 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.

8 Electromagnetic compat ibility (EMC)
8.1 General hints
special precautionary measures as outlined in the EMC information
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. Amo ng st other thi ng s , 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 MPC/MPE at a different location.
• Connect the floor scales MPC/MPE to a different power sour ce.
• 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 pow er units or con nect ing 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.
