4 Basic instructions
4.1 Intended use
The scale you bought is intended for weighing the weighed material. It should be
considered a “non-automatic scale”, e.g. the weighed material should be carefully
placed manually on the scale plate center. The weight can be read after it has
stabilized.
4.2 Non-intended use
Do not use the scale for dynamic weighing. If the amount of the weighed material is
reduced or increased significantly, the scale’s “stabilizing and compensating”
mechanism can result in displaying erroneous weighing results! (Example: slow
outflow of the liquid from the container placed on the scale.)
Do not subject the plate to long-term load. This may damage the weighing
mechanism.
Avoid any scale impact and overload higher than the stipulated maximum load (Max),
deducting the tare from the existing load. This could damage the scale.
Never operate the scale in explosive atmospheres. The standard version is not
explosion-proof.
Never introduce any structural modifications to the scale. This may result in
displaying erroneous weighing results, violating the technical safety conditions, and
also in scale damage.
The scale should always be operated in line with the provided guidelines. Other
operation ranges / areas require a written consent of KERN .
4.3 Warranty
The warranty expires:
• if you fail to follow our guidelines included in the user manual;
• if you fail to use the device in line with the intended use;
• if you introduce any modifications or open the device;
• if the device gets damaged mechanically or damaged by the utilities, liquids and
ordinary wear and tear;
• if the device is not set correctly or the electrical system is not as required;
• if the weighing mechanism gets overloaded.
4.4 Testing equipment super vi s ion
Within the quality assurance system, you must check the technical measurement
properties of the scale and possibly of the available reference weight regularly. To
that aim, the responsible user should define a relevant cycle, as well as the type and
scope of such an inspection. The information on the supervision of the testing
equipment, i.e. scales, and the required reference weights, can be found on the
home page of KERN (www.kern-sohn.com). The reference weights and scales can
be calibrated fast and for a low cost in the KERN calibration laboratory (against the
national reference) approved by DKD (Deutsche Kalibrierdienst).

7 Unpacking, positioning and start-up
7.1 Installation plac e, operat ion place
The scales are designed to ensure reliable weighing results in standard operating
conditions.
The choice of a correct scale location ensures its accurate and fast operation.
This is why you should follow the following rules in the location site:
• Place the scale on stable, flat surface.
• Avoid extreme temperatures and temperature fluctuations, occurring e.g. when
you place it at the radiator or in a place exposed to direct sun rays.
• Protect the scale from the direct draft present at open windows and doors.
• Avoid impact when weighing.
• Protect the scale from high humidity of air, vapors and dust.
• Do not expose it to long-term heavy moisture. Any forbidden condensation of
the air moisture on the device may occur when a cold device is placed in a
much hotter environment. In such circumstances, leave the device not
connected to the mains for 2 hours to adapt to the ambient temperature.
• Avoid static discharge from the weighed material and scale container.
If there are any electromagnetic fields, static discharge and unstable power supply,
high readout deviations (erroneous weighing results) may occur. In such
circumstances, change the location.

7.2 Unpacking and check
Remove the device and accessories from the packaging, remove the packaging
material and place the device in the target location. Check if all components included
in the delivery are present and not damaged.
Scope of delivery / standard accessories
• Scale, see chapter 3.1
• Power supply
• Dust cover

7.2.1 Setting
The correct location is decisive for the accurate weighing results of highresolution analytical and precision scales (see chapter 7.1).
Removing transport protection
Models with an internal adjustment weight:
Follow the description in the information leaflet, either
Replace the brass screw [A] with the steel one [B], to the left of the scale bottom
(follow the description in the yellow information leaflet).
