KERN ALS Series User Manual

24 TALJG_A/TALSG_A/TPLJG_A/TPLSG_A-BA-e-2011
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 supervision
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).
