* Minimum piece weight when counting the number of pieces in laboratory conditions:
There are optimum ambient conditions to count pieces with high resolution
No diversification of the counted pieces’ weight
**Minimum piece weight when counting the number of pieces in standard conditions:
There are unsteady ambient conditions (wind gusts, vibrations)
There is diversification of the counted pieces’ weight

4 Basic instructions (general information)
4.1 Intended use
The scale you bought is intended for weighing the weighed material. It should be con-
sidered 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” mecha-
nism can result in displaying erroneous weighing results! (Example: slow outflow of the
liquid from the container placed on the scale.)
Do not subjectthe 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 explo-
sion-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 oper-
ation 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.

4.4 Testing equipment supervision
Within the quality assurance system, you must check the technical measurement prop-
erties of the scale and possibly of the available reference weight regularly. To thataim,
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) ap-
proved by DKD (Deutsche Kalibrierdienst).
5 Basic safety instructions
5.1 Compliance with the instructions included in the user manual
Before you set and start the device, read this user manual thoroughly
even if you are familiar with KERN scales.
All language versions contain non-binding translation.

Always use the original packaging for the return transport.
Before you dispatch the device, disconnect any connected cables as
well as loose/moving parts.
Reinstall any transport locks, if present.

Protect all the parts, e.g. wind breaker, scale plate, power supply etc.
from slipping and damage.
