2 Basic Information (General)
2.1 Proper use
These balance is used to calculate the weight of people in the private sphere.
Utilisation of this balance in the medical field is not permissible.
A person must stand on the weighing plate for the weighing procedure. As soon as a
stable weighing value is reached the weighing value can be read.
When using balance with height measurement, ensure that the top flap is turned
downwards immediately after use in order to avoid risk of injury.
The balance should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.
2.2 Improper Use
Do not use balance for dynamic weighings. In the event that small quantities are re-
moved or added to the material to be weighed, incorrect weighing results can be dis-
played due to the “stability compensation“ in the balance. (Example: Slowly draining
fluids from a container on the balance. )
Do not leave permanent load on the weighing plate. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the balance,
minus a possibly existing tare load, must be strictly avoided. This could cause dam-
age to the balance.
Never operate balance in explosive environment. The serial version is not explosion
protected.
The structure of the balance may not be modified. This may lead to incorrect weigh-
ing 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.
2.3 Warranty

MPB / MXS -BA-e-0810 5

2.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the bal-
ance and, if applicable, the testing weight, must be checked regularly. The responsi-
ble user must define a suitable interval as well as type and scope of this test. Infor-
mation 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 rec-
ommended for personal balances with body height measurement but is not abso-
lutely essential as the calculation of the human body height is always subject to a
great deal of inaccuracy.

3 Basic Safety Precautions
3.1 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.
3.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
4 Transportation & Storage
4.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appli-
ance itself when unpacking for possible visible damage.
4.2 Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.

5 Unpacking, Setup and Commissioning
5.1 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.
Therefore, observe the following for the installation site:
- Place the balance on a firm, level 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, vapors and dust;
- Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (condensation 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.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.

5.2 Unpacking
Remove the individual components of the balance or the complete balance from the
packaging with care and install at the intended location. When using the power pack,
ensure that the power cable does not produce a risk of stumbling.

5.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage. Only KERN original power packs should be used.
5.4 Battery operation (insertion and removal)
On models where the back of the display unit is not directly accessible, remove the
two black rotary knobs from both sides of the display unit in order to open the battery
compartment and remove the display unit from the holder. Remove battery cover
from under the display unit. Insert 6 x 1.5V AA batteries into the holder. Replace bat-
tery cover and screw the display unit back into the holder using the black rotary
knobs.
In order to save the battery, the balance switches automatically off after 3 minutes
without weighing. Further shutdown times can be set in the Menu
(Function "A.OFF"), see chapter 5.7.
If the batteries are run down, "LO" appears in the display. Press [ON/OFF] -key and
replace the batteries immediately.
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.
5.5 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 warm-
ing up time the balance must be connected to the power supply (mains, accumulator
or battery) and be switched on.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
5.6 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance 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 balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out during the initial start-up, after change in lo-
cation and variation of surrounding temperature. To receive accurate measuring val-
ues it is also recommended to adjust the balance periodically in weighing operation.
Use the adjustment weight (See Technical Data) to check and adjust the accuracy of
the balance at any time.
5.6.1 Procedure when adjusting
Observe stable environmental conditions. A warming up time (see chapter 1) is re-
quired for stabilization.
