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 weighing. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed 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. 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
CWS-BA-e-0610
11
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 storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.
6.2 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. weighing plate,
power unit etc., to prevent slipping 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 installation site:
• 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.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change location or remove source
of interference.
7.2 Unpacking
Carefully remove the balance from the packaging, remove packing material and
place balance at the intended workstation.
CWS-BA-e-0610

Mass terminal
7.2.1 Placing
Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.
7.2.2 Scope of delivery
Serial accessories:
• Balance
• Weighing plate
• Detachable display part
• Mains power supply
• Operating Manual
7.3 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage.
Only use original KERN mains adapters. Using other makes requires consent by
KERN.
Connect the housing to earth, if there is a suspicion that static electricity could pose a
problem.
7.4 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1). During this warming up time the balance must be connected to the power supply (mains, accumulator
or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.

7.5 Storage battery operation (optional)
Installation:
1. Disconnecting the power pack from the balance
2. Unscrew both M3 screws and remove the cover of the battery compartment.
3. Connect wires in the battery compartment to the battery
Connect red wire to positive (+/red) terminal and black wire to negative
(-/black) terminal. Otherwise there is a danger of explosion.
4. Insert battery in compartment and reattach the cover with the help of the
screws.
5. Turn on the balance and check whether the balance is working normally.
Loading the battery
Use the provided power pack for battery charging.
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 15 hours.
• The display [Lo BAT] indicates that the capacity of the battery is nearly exhausted. Connect the power adaptor as soon as possible to change the battery.
• Whilst working in battery mode, [ T ] will be displayed above the battery
symbol
• It is possible to use the balance during charging
• Charge the battery at a temperature ranging between 5°C and 35°C
• Charge the battery at regular intervals (every 3-6 months), when the balance
is not put to use for a longer period of time.
7.6 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.

8.2 Automatic switch-off function AUTO OFF
To save battery life, the balance is equipped with an Auto OFF function.
This switches off the balance after a time of approximately 5 minutes after the last
weighing or key operation. It is possible to enable/disable the Auto OFF function (F04-05) in the menu (see chpt. 14.2).
8.3 Balance zero display/zero tracking
Environmental influences can lead to the exact figure of zero 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. Setting 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.
To reset the balance to zero, press key . A triangle [W ] pops up next to the [ a ]
symbol on the display.
Notice:
The balance has an automatic zero reset function (zero tracking). This function (F04-01) is activated by the factory in order to compensate the normal zero shift due to
variations in temperature, air pressure etc.
In the event that small quantities are removed or added to the material to be
weighed, incorrect weighing results can be displayed due to the “stability compensation“ in the balance. (Example: Slowly draining fluids from a container on the balance).
When apportioning involves small variations of weight, it is advisable to switch off this
function.
If Zero-Tracking however is switched off, the weighing display becomes more busy.
8.4 Stability display
If in the display next to the [ ] symbol a circle [c] appears, the balance is a stable
status. If the status is instable the [c] display disappears.

8.5 Taring
The dead weight of any weighing container may be tared away by pressing a button,
so that the following weighings show the net weight of the goods to be weighed.
Place empty tare container on the weighing plate. The total
weight of the container is displayed.
Press the TARE key.
After dead stop control was carried out, the display is reset
to "0". The weight of the container is now internally saved.

Information:
The balance is able to only store one taring value at a time.
When the balance is unloaded the saved taring value is displayed with negative
sign.
To delete the stored tare, unload the weighing plate and then press the TARE
key; the [W ] display next to "(PRE)-TARE" disappears.
The taring process can be repeated any number of times. The limit is reached when
the whole weighing range is exhausted.
8.6 Simple operating mode
If desired, the balance can be installed in simple operating mode. For this purpose
enable function F-01-01 ( "1"-) in the menu (see chpt. 14.2)
In this mode the use of keys is restricted as follows:
-
In addition the reference weight can be determined by simply weighing (see chpt.
9.2).
CWS-BA-e-0610

9 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.
9.1 Start of add-up process
Turn on balance by pressing the ON/OFF
key. If the display is not on zero, press the

11 Storing a reference weight
11.1 Storing by ID numbers
The balance is able to store up to 99 reference weights with 2 digits ID numbers from
01 – 99. For recall see chpt. 9.4.
The factory default setting of the weighing balance only stores the reference weight.
In addition it is possible to store the container weight and/or the tolerance limits. For
this purpose function F-01-05 must be enabled accordingly (see chpt. 14.2).
1. Input of a reference weight; either nu-
meric or by weighing (chpt. 9.2 -9.3)

12 Adding
The balance is equipped with a summation memory used for adding up of identical
counted parts to total quantity and total weight.
The balance is set by the factory for manual adding-up (by pressing the M+ key). For
automatic adding-up the function F-03-01 must be set to “1” (see chpt. 14.2) in the
menu.
Likewise you can activate the summation data (positive/negative weighing values) in
the menu, see function F-03-02 (chpt. 14.2).
12.1 Manual adding-up by pressing the M+ key
1. Select reference weight and place
number of parts for first weighing.
2. After carrying out a rest position control
add the display value to the summation
memory by pressing the key.
The stored value is indicated by a bleep
and the flashing [W ] display next to
"M+". After dead stop control was carried out the balance will return automatically to counting mode.
123
Place the piece number on the balance for a second weighing and add them to the
memory by pressing the M+ key.
Add and weigh more parts if needed as described above.
Please note that the balance must be unloaded between the individual weighing pro-
cedures (display < +5d).
Note:
If the balance issues four bleeps or if the [W ] display next to "M+" does not flash, the
balance was not unloaded between the individual weighings or the weighing value is
not stable (see also function F-03-02)
Deleting the last M+ sum up
1. Keep pressing the key, press the key, then let go of both.
2. The balance issues a bleep and deletes the last M+ sum up.
If 4 bleeps are sounded, there are no M+ sum ups to delete.
CWS-BA-e-0610
30
12.2 Automatic adding-up
When the automatic summation function F-03-01 is enabled (for setting "1", see chpt.
14.2.), the individual weighing values will be automatically added to the summation
memory without having to press the M+ after a rest position control was carried out.
An acoustic signal indicates when all the weighing values have been added to the
summation memory.
• Same procedure as for manual adding-up, see chpt. 12.1 but without pressing
the M+ key.
• Please note that the balance must be unloaded between the individual weighing procedures (display < +5d).
• If function F-03-02 is set to "1" it is only possible to add positive counts (see
chpt. 14.2.)
12.3 Displaying a sum total
1. Press the key and the total piece
number as well as the number of weighings will appear.
Indicated by the [W ] display next to
"TOTAL" and "N"
2. Press the key again.

12.4 Deleting all stored weighing data
1. Keep pressing the key, press the key, then let go of both.
2. This deletes the M+ memory.
The [W ] display next to "M+" and „TOTAL“ disappears.
Notes:
Pressing the key will delete merely the display but not the data in the sum-
mation memory.
Data remains stored even after the balance was disconnected from the mains.
12.5 M- function
• The balance can subtract summation data from the M+ memory by
pressing the key
• For this purpose enable function F-09-01 in the menu (for setting "1",
see chpt. 14.2).
• This function is not used to delete the last M+ addition but to subtract
the summation data instead of adding. The sum total of the number of
weighings will be increased.
• There is no automatic function M-.

13 Weighing/counting with tolerance range
This function enables weighing of a certain weight or piece number within fixed tolerances, e. g. for control weighings. The achievement of tolerance limits is indicated by
an optical/acoustic signal.

15 Description of individual functions
15.1 ACAI function (automatic counting accuracy improvement = automatic
reference optimisation)
In order to improve add-up accuracy, the
ACAI function calculates the reference
weight anew each time new pieces are
added.
At every reference optimisation, the reference weight is calculated anew. As the
additional pieces increase the base for
the calculation, the reference also becomes more exact.

Kg
111.000
g
28
ACAI notes
• The ACAI procedure must be carried out after setting the reference weight. For
this purpose the piece number must still be on the weighing plate.
• Do not remove the piece number before the ACAI procedure is complete.
• If the pieces remain within the ADAI range, they must not be counted during add-
ing.
• If you want to have the most accurate add-up results for each different batch of
identical pieces, use the ADAI each time when starting a count for a new batch.
• The ACAI function is set by the factory to manual operation if the reference weight
is entered digitally via the keyboard, the ID memory or via PC via serial interface.
This can be converted to automatic mode. The ACAI mode during the input of the
reference weight via ID or digital input is controlled via function F-02-02 (see chpt.
14.2).

the range, the triangle T
will pop up during adding.
When adding is stopped
and the display becomes
stable, the triangle T will
start flashing.
Once the new reference
weight has been calculated, the triangle T will
disappear.
3. Add more pieces within the ACAI range until you have reached a piece number
that is as great as the greatest piece number you wish to count.
4. When you have added the maximum number of required pieces, remove the
pieces and start the add-up procedure.

15.1.2 ACAI manual mode
• During the manual ACAI procedure the reference weight will only be re-calculated
after pressing the ENTER key.
• Setting in menu (chpt..14.2): F-02-01 = „2“
1. Run:
Leave the piece number on the weighing plate after setting the reference
weight
2. Add additional pieces within the next
ACAI range (see table in test passage
above). The triangle T will pop up (
above "AUTO OPTIM." ) as soon as
the weight is within the ACAI range.
3. Wait until the display is stable, then
press the ENTER key. During the calculation of the new reference weight
the triangle T (above "AUTO OPTIM.)
will be flashing for a moment and then
disappear.

15.2 AWA function (audible weighing assist = acoustic fill-to-target)
This function is used to support the approximation to a target piece number (e.g.20
items) by a gradually intensifying acoustic signal.
There are three operating modes. These are selected with the help of the TARGET
key.
Mode off: AWA function disabled
Target mode: Setting a target piece number
Interval mode (int): When in interval mode, a target piece number (e.g. 20
items) for repeat counts may be selected several times
(e.g. 20, 40, 60, 80 items).
• A signal is given starting from "piece number -9". Whilst you are adding pieces
and approach the target piece number the acoustic signal will change the intervals of beeps. These become shorter and will stop as soon as the piece number
has been reached.
• The acoustic signal bleeps again for "target piece number +1, 2, 3 or 4" items.
• The minimum piece number is set to 10.
• If the piece number is set to less than 50 in the interval mode, the acoustic signal
will start sounding at "target piece number -5".
• It is not possible to set a minus target and an interval count at the same time.
However, the AWA function also works for negative piece counts.
• The AWA function must be disabled if the acoustic signal is used for toler-
ance control.
