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

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.

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.

Calibration information (Kern ABJ only)
A security mark must be attached in compliance with the following drawing.
Type plate
Security mark
Important type plate information:
There is a counter on the type plate that counts upwards if the internal adjustment
weight is re-adjusted using service mode. This counter is indicated as follows:
“Log. No. A01”. The display indicates the number A01 after the balance has been
connected to the power supply. If the internal adjustment weight has been adjusted
using the service mode, this counter would count upwards and A02 would appear after
the balance is connected to the power supply. This would invalidate any calibration in
calibrated condition.
The counter on the type plate and the number indicated on the display must coincide
after the balance is connected to the power supply!
If these numbers do not coincide, calibration is not valid.

5 Adjustment
During the set-up, balance sensitivity is adapted to the ambient conditions.
5.1 Adjustment with external weight
Using the recommended adjusting weight (KERN ABS see Chapter 1 „Technical Data“)
or the internal adjusting weight (KERN ABJ), the accuracy of the balance can be
checked at any time and adjusted.
Adjust your new balance at the balance location after a warm-up period before initial
use. If there is any change in location or ambient conditions (particularly temperature),
the balance must be readjusted. This kind of adjustment should be carried out regularly
at all costs due to the high accuracy of the items of equipment.
The weight symbol
becomes necessary.
Sequence:
(1) Remove the items being weighed from the balance plate and press the
TARE/ - key; the display will indicate zero.
(2) Press the CAL/MENU key until E cal appears.
Note: Balances without automatic internal adjustment are set at “E cal” as a
standard, i.e. set for adjustment using an external weight. This setting can
be checked using the “Setting” menu, see chapter 4.4.4, and altered if
necessary.
(3) Then press the TARE/ -key - The display will indicate 0.0000, along with the
weight symbol.
(4) The zero will be flashing. The weight value required for the setting will start to
flash.

9 Important information
These electronic scales are a precision instrument. Electromagnetic fields can cause
major display discrepancies. The scales must then be repositioned away from
electromagnetic fields. All sources of environmental interference, such as drafts and
vibrations, should be avoided. Sudden changes of temperature should be avoided. The
scales must be reset to match changes in temperature.
The scales are not hermetically sealed, therefore avoid high humidity, steam and dust.
Do not bring liquids into direct contact with the scales, as these can penetrate into the
measuring mechanism. Cleaning material should only be dry or barely damp. Do not
use solvents as these can damage paintwork or other plastic parts. Remove damaged
items immediately from the scales.
The measuring mechanism will be stabilised by allowing the scales to warm up for a few
minutes after switching them on. Place items to be weighed carefully on the scales. Do
not place objects on the weighing platform for any period of time, apart from normal
use. Sudden shocks or overloading the scales beyond the maximum permitted weight
should absolutely be avoided, balance could be damaged.
In case of problems operating the weighing program, switch the scales briefly off and
on. The weighing set-up must then be restarted right from the beginning.
Never operate the scales in areas where there is a danger of explosion, the models in
this series are not protected against explosion.
Check the scales regularly against, known, external test weights.
Opening the scales or failing to use them in accordance with the written
instructions will invalidate the warranty.
Please keep all packaging material for possible return of the scales. Scales must only
be returned in their original packaging.
