2 Basic instructions about weighing system
2.1 Proper use
The weighing system 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
loading fork. As soon as a stable weighing value is reached the weighing value can
be read.
5 VFB-BA-e-1310
2.2 Improper Use
The weighing system is not suitable 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 weighing system.
(Example: Slowly draining fluids from a container on the weighing system.)
Do not leave permanent load on the loading fork. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. The weighing
system could be damaged.
Never operate the weighing system in an explosive environment. The serial version
is not explosion protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the weighing
system.
The weighing system unit may only be operated in accordance with the described
default settings. Other areas of use must be released by KERN in writing.
2.3 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 and damage caused by media, liquids
Natural wear and tear
Improper setup or incorrect electrical connection
The measuring system is overloaded
2.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
weighing system 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.
VFB-BA-e-1310 6
Carefully read this operation manual before setup and
commissioning, even if you are already familiar with KERN
balances.
All language versions contain a non-binding translation.
The original German is binding.
Keep all parts of the original packaging for a possibly
required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.

5.2 Proper use of the lifting device
VFB-BA-e-1310 10
Incorrect lifting of a load
Correct lifting of a load
5.3 Installation site, location of use of the weighing system
The weighing system is designed to achieve reliable weighing results under normal
conditions of use.
You will work accurately and fast, if you select the right location for your weighing
system.
Therefore, observe the following for the installation site:
The load must be lifted clear of the display unit’s case and other pallets.
The accuracy of the weighing system is falling by approximately 0.1 % per
degree if there is a slant of more than 2°. Holes and unevenness, too, have
this effect. A smooth floor is ideal.
Optimum accuracy in weighing results is achieved if the load centre is
between the forks. The forks are easily bent and twisted when the load is offcentre. This may result in diminished accuracy.
In verifiable models off-centre loads, or slants affecting accuracy, activate the
inclination switch which in turn disconnects the display.

Non-optimal positioning of load
Optimal positioning of load
Pallet
Load
Temperature range: The maximum deviation for 0.1% of the weighed load is
between -10 and +40°C. Outside this temperature range deviations of up to
0.3% may occur.
Avoid jarring during weighing
Protect the weighing system 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.
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.

5.6 Rechargeable battery operation
Before the first use, the battery should be charged by connecting it to the mains
power supply for at least 12 hours.
The appearance of the rechargeable battery symbol in the weight display indicates
that the battery is almost exhausted. The unit will be ready for operation for approx.
another 10 hours before switching off automatically. Charge the battery with the help
of the supplied power pack. During the loading process the rechargeable battery
symbol is displayed flashing.
The rechargeable battery symbol shows the charge status of the rechargeable
battery:

6 Linearization
Carrying out linearization is restricted to specialist staff possessing well
acquainted with the workings of weighing scales.
The test weights to be used must be adapted to the weighing scale’s
specifications; see chapter 2.4 “Testing instruments control”.
Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
After successful linearization you will have to carry out an adjustment.
Linearity shows the greatest deviation of a weight display on the scale to the value of
the respective test weight according to plus and minus over the entire weighing
range.
If linearity deviation is discovered during a testing instrument control, you can
improve this by means of linearization.

After the linearization the weighing system should be adjusted as
follows:
VFB-BA-e-1310 20
7 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. A warming up time (see chapter 1) is
required for stabilization. Ensure that the system is not loaded. The system should
be lifted by approximately 2 lifting index markings and stand absolutely free.

10 Servicing, maintenance, disposal
10.1 Clean
Please do not use aggressive cleaning agents (solvents or similar agents), but a
cloth dampened with mild soap suds. Ensure that no liquid penetrates into the device
and wipe with a dry soft cloth.
10.2 Servicing, maintenance
The same maintenance guidelines apply to the chassis of the mobile weighing
system as those for simple manual pallet trucks. Experience has taught us that the
integrated weighing system continues to function even if the chassis was damaged
by overloading.
General rules:
As the steering wheels are mounted at the front, it is better to pull rather than
push the pallet truck scale.
If the lifting device is not used, the manual lever should be left in centre
position. This prolongs the life span of the seals.
To prevent damages to the electronic system and weighing cells it is
necessary that welding work on the entire weighing system is carried out
exclusively by technical specialists.
The bearings of the wheels (with the exception of polyurethane) as well as the
joints in the load roller section should be regularly cleaned and greased.
10.3 Disposal
Disposal of packaging and appliance must be carried out by operator according to
valid national or regional law of the location where the appliance is used.
