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.

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.

9 Verification
General introduction:
According to EU directive 90/384/EEC balances must be 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 instructions
An EU type approval exists for balances described in their technical data as
verifyable. If a balance is used where obligation to verify exists as described above,
it must verified and re-verified in regular intervals.
Re-verification of a balance is carried out according to the respective national regulations. The validity for verification of balances in Germany is e.g. 2 years.
The legal regulation of the country where the balance is used must be observed!
After verification the balance is sealed at the indicated positions.
Verification of the balance is invalid without the "seal".
Position of the “official seals“:
Balances with obligation to verify must be taken out of operation if:
- 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.

13 Descri pt ion of individual functi ons
13.1 Stability filter
Generally, data processing for greater stability slows the response and processing
for higher response reduces stability. Balances of the series ABT are designed to
ensure both qualities, that is, fast reaction time and high stability.
Most measurements can be carried out using default settings, that is, standard
mode. In specific environmental conditions and for specific measuring purposes anticonvection, high stability or apportioning mode is available for you to use. The currently set mode is shown on the setting control display (see ch. 12.6).
13.1.1 Standard mode
This is the default setting. Use this mode unless stability or response has to be increased or reduced.
Repeatedly press the [CAL] key until "Stnd".
To set standard mode, press the [TARE] key.
Setting of this mode can be confirmed only in settings check dis-
play (see ch. 12.6).

13.1.2 Anti-convection mode
If measurements have to be taken under unavoidable ambience conditions, (e. g.
changing air condition systems) convection occurring within the weighing space may
result in fluctuations in the display on the balance after the stability display has appeared. The small range (readability 0.01 mg) of series ABT is particularly susceptible to this effect.
Anti-convection mode adjusts the timing of appearance of the stability mark. Note
that the stability mark will then appear at a late timing.
Repeatedly press the [CAL] key until "ConvECt" appears.
To set anti-convection mode, press the [TARE] key.
Setting of this mode can be confirmed only in settings check
display (see ch. 12.6).
13.1.3 High-stability Mode
The balances of series ABT are designed to react only minimally to the effects of
vibrations and drafts. However, if it must be set up in a location with poor conditions,
use this function to reduce the effects of vibration or air current even further. There is
a slight increase in the reaction time of the balance but the display itself is stabilized.
Repeatedly press the [CAL] key until "ConvECt" appears.
To set high stability mode, press the [TARE] key.
Setting of this mode can be confirmed only in settings check

14 Application Functions
14.1 Parts counting
With parts counting you can either count parts into a container or remove parts from
a container. To count a greater number of parts the average weight per part has to
be determined with a small quantity (reference quantity). The larger the reference
quantity, the higher the counting exactness. High reference must be selected for
small parts or parts with considerably different sizes.
The process has four steps:
• Tare the weighing container
• Determine the reference unit
• Weigh in the reference unit
• Count the items
Condition: Function "U- PSC" activated (ch. 11.3)
(When PCS is used for the
first time)
Repeatedly press the [UNIT] until display is in percentage
mode. The display symbol PCS pops up.
If you are using a weighing container use the [TARE] key for
taring.
To determine the reference piece number, place 10, 20, 50 or
100 counting parts on the balance.
Press the [CAL] key
Repeated pressing of the [CAL] key allows the change between
the following reference piece numbers "Ld 10", “Ld 20”,“Ld 50”
and “Ld 100”.
Important: The larger the reference quantity, the more accurate
the parts counting.
(When loading 20 pieces)
When standstill control ( ) is complete, confirm your reference
piece number by pressing the [TARE] key.
The display shows "SEt" for several seconds and the stored
reference piece number is displayed.
ABT-BA-e-1312
55
Remove reference weight.
Now you can fill the items to be counted into the container.
The respective quantity is shown in the display.
Repeated pressing of the [UNIT] key changes the display value,
e. g.: [g] → [%] → [Pcs] → [ct]
Note:
Error message "Err 20" indicates that the weight for the reference piece number is
too low.
14.2 Percent determination
Percent weighing allows to display weight in percent, in relation to a reference
weight. The displayed weighing value is stored as a standard percent value
(default setting: 100%).
Condition: Function "U- %" is activated (ch. 11.3)
(When PCS is used for the
first time)
Repeatedly press the [UNIT] key until the display is in percent-
age determination mode. The display symbol % pops up.
If you are using a weighing container use the [TARE] key for
taring.
Put on reference weight (=100%)
(minimum weight: Readability d x 100)
When standstill control ( ) is complete, press the [CAL] key.
The reference weight is saved.
Remove reference weight.
From now on the placed weight will be shown as %.
Repeated pressing of the [UNIT] key changes the display value,
e. g.: [g] → [%] → [Pcs] → [ct]
