3 Fundamental information (general)
3.1 Intended Use
The balance you have acquired serves to determine the weighing value of the
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. The weighing value can be read off after a stable weighing value has
been obtained.
3.2 Inappropriate use
Do not use the 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 a permanent load on the weighing plate. This can damage the
measuring system.
Be sure to avoid impact shock and overloading the balance in excess of the
prescribed maximum load rating (max.), minus any possible tare weight that is
already present. This could cause damage to the balance.
Never operate the balance in hazardous locations. The series design is not
explosion-proof.
Structural alterations may not be made to the balance. This can lead to incorrect
weighing results, faults concerning safety regulations as well as to destruction of the
balance.
The balance may only be used in compliance with the described guidelines. Varying
areas of application/planned use must be approved by KERN in writing.
3.3 Guarantee
The guarantee is not valid at the following:
•non-observation of our guidelines in the operating instructions
•use outside the described applications
•alteration to or opening of the device
•mechanical damage and damage caused by media, liquids, natural wear and tear
•inappropriate erection or electric installation
•overloading of the measuring equipment
PLS/PLJ/ALS/ALJ-BA-e-0819 43

3.4 Monitoring the test substances
The metrology features of the balance and any possible available adjusting weight
must be checked at regular intervals within the scope of quality assurance. For this
purpose, the answerable user must define a suitable interval as well as the nature
and scope of this check. 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. Test weights and balances can be adjusted quickly and at a
reasonable price in KERN’s accredited DKD calibration laboratory (return to national
normal).
4 Fundamental safety information
4.1 Observe the information in the operating instructions
Please read the operating instructions carefully before erecting and commissioning,
even if you already have experience with KERN balances.
4.2 Staff training
The device may only be operated and looked after by trained members of staff.
5 Transport and storage
5.1 Acceptance check
Please check the packaging immediately upon delivery and the device during
unpacking for any visible signs of external damage.
5.2 Packaging
Please retain all parts of the original packaging in case it should be necessary to
return items at any time.
Only the original packaging should be used for return consignments.
Before despatch, disconnect all attached cables and loose/movable parts.
Apply any intended transport security devices. Secure all parts e.g. weighing plate,
mains power supply etc. against slipping and damage.
PLS/PLJ/ALS/ALJ-BA-e-0819

6 Unpacking, installation and commissioning
6.1 Place of installation, place of use
The balance is constructed in such a way that reliable weighing results can be
achieved under normal application conditions.
By selecting the correct location for your balance, you will be able to work quickly and
precisely.
Therefore please observe the following at the place of installation:
•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.
Inadmissible bedewing (condensation of air moisture on the device) can occur
if a cold device is taken into a significantly warmer environment. In this case,
please acclimatise the device for approx. 2 hours at room temperature after it
has been disconnected from the mains.
•Avoid static charging of items to be weighed, or weighing container.
Major display deviations (incorrect weighing results) are possible if electromagnetic
fields occur as well as due to static charging, currents and instable power supply. It is
then necessary to change the location.
6.2 Unpacking
Carefully remove the balance from its packaging, remove the plastic wrapping and
position the balance in its intended working location.
PLS/PLJ/ALS/ALJ-BA-e-0819 45

6.2.1 Installation
Use the foot screws to level the balance until the air bubble in the bubble level is in
the prescribed circle.

6.2.2 List of items supplied
Standard accessories:
•Balance
•Weighing plate
•Mains device (Power adaptor)
•Operating Instructions
•Draft shield (only for models up to d = 1mg)
•Protective working cover
6.3 Mains supply
Electric power supply is by means of the external mains supply circuit. The printed
voltage level must comply with the local voltage.
Only use original KERN mains supply circuits. The use of other makes is subject to
approval by Kern.
6.4 Connection of peripheral equipment
The balance must be disconnected from the mains before connecting or
disconnecting additional equipment (printer, PC) to or from the data interface.
Only use KERN accessories and peripheral equipment with your balance. These
have been ideally coordinated to your balance.
6.5 Initial start-up
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).
For verified balances series PLJ…-3M there is warming up time, during which the
display indicates [burn - in].
The accuracy of the balance depends on the local acceleration of the fall.
Instructions in chapter Adjustment must be observed.
6.5.1 Power display
If this character [ : : ] is visible, the balance it supplied with power via the mains
power supply. Actuating the ON/OFF –button will switch the balance into weighing
mode.
This way, the power display in the display overview is no longer visible.
6.5.2 Stability display
If the display shows the stability display [ ] the balance is in a stable status. If the
status is instable the [ ] display disappears (see also chapter 8.2.1). Stable
environment conditions may be reached by using a draft shield.
PLS/PLJ/ALS/ALJ-BA-e-0819 47

6.5.3 Balance zero-display
If the balance does not show exactly zero although the pan scale is unloaded, press
the TARE-button and the balance will be reset to zero [ a].
6.5.4 Auto-zero-function
In the menu you can turn on or off the auto-zero-function. To do so, proceed as
follows:
ÖTurn on balance using the ON/OFF-button
ÖPress the Tare-button; the display shows horizontal lines
ÖWhile this display shows, press the CAL-button, until AUtO is displayed
ÖPress the PRINT-button; the display now shows the current menu item
blinking
ÖUse the F-button to choose between the following settings:
AUtO 0: Auto-zero-function activated
(Display [ /a])
AUtO 1: Auto-zero-function deactivated
ÖUse the PRINT-button to confirm the selected setting
6.6 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. It is
also recommendable to adjust the balance periodically during weighing operation in
order to obtain exact measured values.
PLS/PLJ/ALS/ALJ-BA-e-0819
48

6.6.1 Adjusting with internal weight (only PLJ/ALJ)
The installed adjusting weight allows checking and resetting the weighing accuracy at
any time.
The automatic adjustment function is always active.
You can also start adjustment manually by pressing the Cal-button.
Automatic adjustment is started when the balance is
•cut off from power supply,
•when changing temperature
•after a time interval
Temperature / time controlled adjustment is taking place:
5 minutes before the start of automatic adjustment, this will be announced by a "º C“,
(change of temperature) or a “►“ (after a certain time interval ends) symbol on the
display. The user must complete his/her weighing process within this time. After 5
minutes [ CAL 30 ] appears on the display. This starts a “count down” of 30 seconds
[ CAL 30 ] →[ CAL 0]. During these 30 seconds it is possible to cancel the
adjustment by pressing the TARE key. This makes the balance return to weighing
mode in order to e. g. complete an unfinished measurement.
6.6.2 Adjusting with external weight (only PLS/ALS)
Carry out adjustment with the recommended adjusting weight (see Chapter 1
„Technical Data“).
Procedure for adjustment:
Observe stable environment conditions. A warming-up time of ca. 2 hours for
stabilisation is necessary.
ÖUse the ON/OFF-button to turn on the balance.
ÖPress CAL-button; the display shows NO CAL.
ÖWait until LOAD is displayed, then place adjusting weight (see Chapter
1 „Technical Data“) carefully in the centre of the weighing plate.
ÖThe display shows CAL, adjustment is started.
ÖThe display shows UNLOAD, adjustment is completed.
ÖRemove adjusting weight, the balance will automatically return to
weighing mode.
In case of an adjustment error or wrong adjusting weight CAL Err is displayed;
repeat adjustment process
Keep test weight with the balance. Daily checking of the weighing accuracy is
recommended for quality-relevant applications.
PLS/PLJ/ALS/ALJ-BA-e-0819 49

6.7 Verification
General:
According to the EU guideline 90/384/EEC balances must be verified officially if they
are to be used as follows (legally regulated 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 the production of finished packages
In case of doubt, please contact your local office of weights and measures.
Verification information
An EU qualification approval is available for those balances marked as appropriate
for verification in the technical data. In the event that the balance is applied in an
area subject to verification as described above, it must be officially verified and re-
verified at regular intervals.
Re-verification of a balance is carried out in compliance with the respective legal
provisions of the states. The term of verification validity for balances in Germany, for
example, is normally 2 years.
The legal provisions of the country of use are to be observed.
After verification the balance is sealed at the marked positions.
Verification of the balance is invalid without the seal.
Position of the seal:
Seal
Balances with obligatory verification must be taken out of service if:
- The weighing result of the balance is outside the maximum limits of
operating errors. Therefore load balance is regular intervals with known test
weight (ca. 1/3 of the max. load) and compare with displayed value.
- The date for subsequent or periodical verification has passed.

6.8 Under floor weighing
Using under floor weighing allows weighing of objects that because of their size of
shape cannot be placed on the pan scale.
Proceed as follows:
•Turn off balance.
•Open the closing lid at the bottom of the balance.
•Carefully and completely hook in the hook for under floor weighing.
•Place balance over an opening.
•Suspend the item to be weighed from the hook and carry out weighing.
Fig. 1: Setting up balance for under floor weighing
CAUTION
•Ensure that all suspended objects are stable enough to hold the desired items
to be weighed securely (danger of breaking).
•Never suspend loads that exceed the stated maximum load (Max)
(danger of breaking)
Always ensure that underneath the load there are no living beings or objects that
might be damaged.
!
NOTE
When the under floor weighing the opening in the bottom of the balance must be
closed (protection against dust).
