4 Basic Information (General)
4.1 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 material 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.
4.2 Improper Use
Do not use balance for dynamic add-on weighing procedures, if small amounts of
goods to be weighed are removed or added. The “stability compensation“ installed in
the balance may result in displaying an incorrect measuring value! (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. Balance may be damage by this.
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 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.
4.3 Warranty
Warranty claims shall be voided in case
• Our conditions in the operation manual are ignored
• The appliance is used outside the described uses
• The appliance is modified or opened
• Mechanical damage or damage by media, liquids, natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
ABT-BA-e-1312
12
4.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related 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.
5 Basic Safety Precautions
5.1 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.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
6 Transport and stora ge
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
ABT-BA-e-1312
13
6.2 Packaging / return transport
Keep all parts of the original packaging for a possibly re-
quired return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.
Reattach possibly supplied transport securing devices.
Secure all parts such as the glass wind screen, the weighing
platform, power unit etc. against shifting and damage.

7 Unpacking, Setup and Commissioning
7.1 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 i nstallation site:
• Operate the device only indoors.
• 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, 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 appliance for ca. 2 hours at room
temperature.
• Avoid static charge of goods to be weighed or weighing container.
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.
7.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.

in the figure.
• Carrier of weighing plate, attach
weighing plate and circular screen in
order.
• Level balance with foot screws until
the air bubble of the water balance is
in the prescribed circle.
• When the key panel and the display
must be protected from dirt and wear,
place the cover over the key panel.

7.3 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.
7.4 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.
Terminal for external devices:
1 RS -232 interface

7.5 Initial Commissioning
A warming up time of 4 hours after switching on stabilizes the measuring values.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
7.5.1 Turning On the Power
1. Supply power to balance via mains
adapter. After the balance performs a
self check, calibration will be automatically executed. During this process, the
display will change as follows. “CHE 5”,
“CHE 4”...... “CHE 0”, “CHE 2”, “CHE 1”
, “CAL 2 – CAL 0” , “CAL-End”, “oFF”.
This adjustment can be interrupted immediately after switching-on the power
supply by actuating the [ON/OFF]-key.
However, at least one adjustment must
be carried out before the balance can
be used.
2. Actuate the [ON/OFF] key. After all dis-
plays appear, the gram (g) symbol ap-
pears.
3. Pressing the [ON/OFF] key again turns
on the standby symbol and puts the
balance in standby (warm up) status.
Current time (see ch. 13.5) will be displayed.
ABT-BA-e-1312
20
8 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 receive accurate measuring values it is also recommended to adjust the balance periodically in weighing operation.
Observe stable environmental conditions. Stabilisation requires a warm-up period of
1 or 4 hours (for models d = 0.01 mg). Ensure that there are no objects on the
weighing plate.
8.1 Automatic adjustment via PSC
The default setting for balances of the series ABT ("PSC ON") prompts automatic
adjustment via the PSC function.
The moment a change in temperature is detected this function uses the internal tare
weight to carry out fully-automatic adjustment with the help of a temperature sensor.
If PSC is left ON, when there is a temperature change that would influence sensitivity, span calibration executes automatically to maintain the sensitivity of the balance.
Adjustment in weighing mode is carried out automatically under the following conditions:
(1) If a change in environmental temperature (0.5 °C) occurs;
(2) When about four hours has passed since the previous calibration.
(3) When the balance is switched from standby status to weighing mode
and condition (1) or (2) has been met.
(4) When balance was disconnected from the mains.
If one of the above conditions was met in weighing mode, the weight symbol flashes
for about two minutes in order to notify the pending adjustment; afterwards the display will show "PSC run". During operation, the display will automatically change and
the motor sound of the weight loading system is heard. In order to ensure proper
PSC operation, prevent vibrations and air flow. As soon as the display in grams reappears after completing adjustment via PSC, the balance returns to weighing mode.
The sensitivity before and after adjustment is slightly different. Also, no measurements can be made during adjustment. To prevent a start-up of adjustment during a
measuring process you have to actuate the [ON/OFF] key as soon as the weight
symbol starts flashing. This will interrupt automatic adjustment.

8.2 Automatic adjustment via Clock-CAL
(only models ABT 100-5M, ABT 120-5DM, ABT 220-5DM)
With the help of its internal adjusting weight and integrated clock the balance can be
set to carry out automatic adjustment at set times (up to three times daily). ClockCAL is a very convenient function, when calibration reports are desired to be made
for regular calibrations, or when wishing span calibrations during break times to avoid
interruption of measurement work.
The weight symbol blinks for about two minutes as notification of span calibration
before it begins. Automatic adjustment can be stopped by actuating the [ON/OFF]
key during this message.
