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.

10 Unpacking, Setup and Commissioning
10.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
On the installation site observe the following:
• Place scales on a stable, even surface;
• Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight;
• Protect the balance against direct draughts due to open windows and doors;
• Avoid jarring during weighing;
• Protect the balance against high humidity, vapours and dust;
• Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (co ndensation of air humidity on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
• Avoid static charge of the balance and of the person to be weighed.
• Avoid contact with water.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. Change location or remove
source of interference.
10.2 Unpacking
Remove the individual components of the balance or the complete balanc e from the
packaging with care and install at the intended location. When using the pow er pack,
ensure that the power cable does not produce a risk of stumbling.

10.8 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1). During this
warming up time the balance must be connected to the power supply (mains,
accumulator or battery) and be sw i tc hed on.
The accuracy of the balance depends on the local acceleration of gravity.
The value of gravity acceleration is shown on the type plate.

You can print weighing data automatically via the RS 232 interface or manually by
pressing mit (MPE) bzw. (MPC) via the interface according to the setting
in the menu.
This data exchange is asynchronous using ASCII - Code.
The following conditio n s must be met to provide successful communication between
the weighing balance and the printer.
• Use a suitable cable to connect the weighing balance to the interface of the
printer. Faultless operation requires an adequate KERN interface cable.
• Communication parameters (baud rate, bits and parity) of balance and printer
must match. For detailed description of interface parameters see chap. 12.1)
In a medical context only auxiliary equipment in compliance with Directive
EN 60601-1 may be connected to the interface.
• Excess load, during zero setting of weighing scale
• Incorrect adjusting process
• Fault on load cell
Value outside the A/D converter range
• Damaged weighing cell
• Damaged electronics
Should other error messages occur, switch balance off and then on again. If the error
message remains inform manufacturer.

Clean weighing platform (such as seat) as well as casing with household detergents
or commercially available disinfectants. Please follow manufacturer’s instructions.
Do not use abrasive or aggressive cleaners such as spirits or alcohol or similar as
they might damage the high-quality surface.
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).
Do not spray disinfectants onto appliance.
Make sure that disinfectant does not penetrate the interior of

17 Verification
General introduction:
According to EU directive 2009/23/EC balances must be officially verified if they are
used as follows (legally controlled area):
a) For commercial transactions if the price of goods is determined by weighing.
b) For the production of medicines in pharmacies as well as for analyses in the
medical and pharmaceutical laboratory.
c) For official purposes
d) For manufacturing final packages
In cases of doubt, please contact your local trade in standard.
Verification notes:
An EU type approval exists for balances described in their technical data as
verifiable. If a balance is used where obligation to verify exists as described above, it
must be verified and re-verified at regular intervals.
Re-verification of a balance is carried out according to the respective national
regulations. For verification validity period, s. chap. 17.1.
The legal regulation of the country where the balance is used must be observed!
Verification of the balance is invalid without the seal.
The seal marks attached on balances with type approval point out that the
balance may only be opened and serviced by trained and authorised
specialist staff. If the seal mark is destroyed, verification looses its validity.
Please observe all national laws and legal regulations. In Germany a reverification will be necessary.
The weighing result of the balance is outside the error limit. Therefore, in
regular intervals load balance with known test weight (ca. 1/3 of the max.
load) and compare with displayed value.
The reverification deadline has been exceeded.

18 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate must be coordinated - in compliance
with the underlying physical weighing principle - to the existing acceleration due to
gravity at its place of location (only if the weighing system has not already been
adjusted to the location in the factory ) . This adjustment process must be carried out
for the first commissioning, after each change of location as well as in case of
fluctuating environment temperature. To receive accurate measuring values it is also
recommended to adjust the display unit periodically in weighing operation.
•Prepare the required adjustment weight. The adjustment weight to be
applied depends on the capacity of a weighing scale, see chap. 1.
Carry out adjustment as closely as possible to admissible maximum
load of weighing scale. Information about test weights you will find in the
internet under http://www.kern-sohn.com
•Observe stable environmental conditions. For warm-up time required for
