3. Basic Information (General)
3.1. Proper use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the mate-
rial to be weighed is manually and carefully placed in the centre of the weighing plate.
As soon as a stable weighing value is reached the weighing value can be read.
3.2. 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 damage 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 incor-
rect 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.
The appliance may only be opened by trained service technicians according to
KERN standards.
Before opening, disconnect appliance from power supply!
Warranty claims will be voided when appliance is opened.
The PES/PEJ weighing system may not be used in explosive areas or areas
with explosive substances.
3.3. Warranty
Warranty claims shall be voided in case
our conditions in the operation manual are ignored
the appliance is used outside the described uses
when 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

PES/PEJ-BA-defsi-0510 97
3.4. 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.
4. Basic Safety Precautions
4.1. 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.
4.2. Personnel training
The appliance may only be operated and maintained by trained personnel.
5. Transport and storage
5.1. Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2. Packaging
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts, e.g. glass windshield,
weighing plate, power unit etc., to prevent slipping and damage.

6. Unpacking, Setup and Commissioning
6.1. 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 install-
ing 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 (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 appli-
ance for ca. 2 hours at room temperature.
Avoid static charging of the material to be weighed, weighing container
and windshield.
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.
6.2. Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.

6.5. Mains connection
Power is supplied via the external mains power supply. The stated voltage value
must be the same as the local voltage.
Only use original KERN mains power supplies. Using other makes requires consent
by KERN.
In the menu you can activate the AUTO-SLEEP function !A. A.u.1".In net operation
the balance after 3 min without load change or key pressure passes in a sleep mode.
Automatic activation of the display by load change or by pressing any key.
6.6. Internal battery operation (cannot be reequipped)
The optionally supplied battery is charged with the supplied power supply.
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 15 hours. The operating time of the battery is about. 6h;
charging time until complete recharging ca. 15h.
In the menu you can activate the AUTO-OFF function !y A.P.1". After 3 min without
load change the balance switches automatically off in order to spare the battery.
When the balance is in battery mode the following symbols appear on the display:
Battery charge sufficient
Battery very low. To charge the battery, connect it to the mains
as soon as possible (re-calibration not possible).
flashes
Voltage has dropped below prescribed minimum. Plug in the
mains adapter, to charge the balance via the electrical network
(15h).
6.7. Terminal for external devices
The output for the external devices is situated under the cover plate on the rear of the
balance. To remove the cover platte, loosen the two fastening screws.

6.8. Initial Commissioning
A warming up time of 10 minutes after switching on stabilizes the measuring values.
The accuracy of the balance depends on the local acceleration of gravity.
Please be sure to observe the information in the chapter on adjusting in chap. 6.9.

The weighing range of the balance is divided into 40 graphic cuboids. Zero (0) will
appear on the graphic display if there is no weighing value on the balance. 20 graphic
cuboids are displayed if the balance is loaded up to one half of its weighing range.
6.8.3. Stability display
Stable
Unstable
If the display shows the stability display []the balance is in a stable status. The []
indication disappears if the condition is unstable.
6.8.4. Balance zero display
Environmental influences can lead to the exact figure of “000.0“ not being displayed
in spite of an empty weighing dish. It is, however, possible to reset your balance to
zero at any time and thus ensure that weighing really does commence at zero. Set-
ting to zero when a weight is applied is only possible within a certain type-dependent
range. In the event that the balance cannot be reset to zero with an applied weight,
this range has been exceeded. [o - Err ] will appear on the display.
If an exact zero reading is not displayed on the balance in spite of the weighing dish
being empty, press the TARE key and the balance will start resetting to zero. Your
balance will be set to zero after a short standby time.
In addition to this, the sign for the balance zero setting will be displayed [#0$].

6.9. 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 for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To re-
ceive accurate measuring values it is also recommended to adjust the balance peri-
odically in weighing operation.
6.9.1. Adjustment with external weight (only PES)
Adjustment is possible with the delivered check weight, but for reasons of measuring
technique, not always optimal. We recommend the following adjustment weights:
Model Recommended adjustment
