4 Basic instructions (general information)
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
The scale is not intended for dynamic weighing, e.g. for removing or adding small
amounts of the weighed material. 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 impactand 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 introduceany structuralmodifications tothe 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 Guarantee
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.
