2.3 Important notices
2.3.1 Ambient conditions
The items of equipment are constructed to provide reliable
weighing results under normal ambient conditions in a
functioning laboratory. A suitable location for the balance will
make it easier to obtain fast, reliable results with the balance.
The following steps must be taken when siting the balance:
Place the balance on a flat, stable surface;
Prevent extreme heat due to placement near a heat source
or direct sunlight;
− Protect the balance from direct air currents due to open
doors or windows;
− Prevent strong vibrations during weighing;
− Protect the balance from harsh chemical vapours;
− Do not use the balance in areas where there is any risk of
explosion.
Do not expose the apparatus to high humidity for extended
periods of time. Dew (condensation due to moisture in the
apparatus) may result when transferring the apparatus from
a cold area to a noticeably warmer environment. In this
case, acclimatise the apparatus to the ambient temperature
for about 2 hours.
Avoid magnetic and electric fields around the balance.
Check the balance with the verification weights at least once
a day.
The warranty is voided if the balance is opened.
ABS/ABJ-BA-e-1019

2.3.2 Operating instructions for the balance
Remove the product from the weighing plate after
weighing it.
Do not force the balance to open.
Do not allow the balance to come into contact with water
or metal shavings.
If the balance is not used for an extended period of time
(7 days), unplug the power supply.
Do not weigh magnetic objects.
Do not exert any pressure on the weighing plate.
2.4 Balance installation
Remove the adhesive sheeting, adhesive strips and foam
material.
2.4.1 Prepare the weighing chamber.
Place the following parts on the balance in sequential
order:
- Protective ring (4)
- Plate holder (3)
- Plate (2)
10
ABS/ABJ-BA-e-1019
2.4.2 Power connection
The balance is powered by an external power supply. The
voltage printed on the device must match the local mains
voltage.
Note!
Use only original power supplies. The use of other brands,
even if authorised by official agents, must be approved by a
specialist.
Plug the balance into the power outlet.
Turn on the power supply at the mains voltage.
Make sure there are no objects on the weighing plate.
The balance will work through a check procedure. In
addition, ABJ series balances carry out calibration using a
fitted calibration weight.
The “oFF“ message will appear on the display.
The balance will then be in standby mode. Press the
"ON/OFF" key to turn on the balance.
2.4.3 Connection of electrical components (peripherals)
Unplug the balance from the power outlet before connecting
or removing additional devices (printer, PC) from the data
interface.
2.4.4 Levelling the balance with the level
Use the support screws to level the balance until it is
horizontal and the air bubble is inside the red circle.

Standby
CHE 5
In order for the balance to provide accurate results, the
device must be warmed up for at least 4 hours after being
plugged for the first time or after an extended power
outage. After this time, the balance will have reached the
necessary operating temperature.
To turn the display on and off, use the ON/OFF/ESC key.
An automatic function test of the balance electronics is
carried out after switching on from standby mode. At the
end of the test, the display will indicate zero. The balance is
now ready to be used.
The following symbols will appear in the display window of
the balance for information purposes:
The balance is in OFF mode.
The balance is not plugged into the power mains.
(New connection, power outage above 1 second)
The balance is in standby mode.
The display was turned off by pressing the ON/OFF/ESC
key and is now available. The balance is ready to run when
turned on and does not require a warm-up period. In
addition, the time is displayed on the ABJ model in standby
mode.
The CHE display appears after the power is turned on.
The balance will work through a check procedure (5, 4, 3, 2,
and then switch to OFF mode.

2.5.4 Taring
2.5.5 Simple weighing (weight measurement)
2.5.6 Unit change-over
Accurate weighing is only possible if the display indicated
0.0000 g before the objects were weighed. Press the
TARE/ key to zero the weight display. Taring can be
done over the entire weight range of the balance.
Place the item to be weighed on the plate. Read the weight
when the standby symbol appears on the display.
The units set in the balance operation menu can be called
up by pressing the UNIT/ key.
2.6 Data interface
The interface connection is located at the rear of the
balance.
Note!
Unplug the balance from the power outlet before connecting
or removing additional devices (printer, PC) from the data
interface.
To output data, press the PRINT/

2.7 Care and maintenance
2.7.1 Cleaning
2.7.2 Safety check
Always unplug the device from the power outlet before
cleaning the apparatus.
Do not use harsh cleaning products (solvents or similar)!
Use a damp cloth, moistened with a mild soapy solution.
Make sure no moisture enters the apparatus, wiping with a
soft, dry towel.
Remove any test residue/dust with care by using a fine
paintbrush or hand vacuum cleaner.
If risk-free service is no longer guaranteed, you must place
the apparatus out of service by unplugging it from the power
outlet and protecting from further use.
Risk-free service of the power supply is no longer
guaranteed in the following cases.
- If the power supply is obviously damaged
- If the power supply no longer works
- After extended storage under adverse conditions.
In such cases, you must contact the supplier.
Any repairs must be performed by specialised technicians
with access to the necessary repair documentation and
instructions.
