2 Safety precautions
Product safety plays an important role at KERN & Sohn.
Non-observance of the following instructions can lead to damage to the weighing
platform and/or injuries.
Before using the weighing platform read these instructions. Store these
nstructtions for future use.
Take care when transporting or lifting heavy devices.
Only qualified personnel may install and maintain the weighing platform.
Disconnect the weighing terminal from the power supply before carrying out
cleaning, installation and maintenance.
The weighing platform must have stabilized to room temperature before the sup-
ply voltage is switched on.
Do not use the weighing platform in hazardous environments.

3 Setting up the weighing platform
• The surface must be able to bear
3.1 Selecting the site of installation
3.2 Package volume
the weighing platform under maximum load at the points of support.
At the same time it should be so
stable that no vibrations arise during weighing. This is also to be observed when installing the weighing
platform in conveyor and similar
systems.
• If possible, vibrations from neigh-
boring machines should not occur
at the site of installation.
• Weighing plate (stainless steel)
• Protect screw

Only use original packaging for returning.
Reattach supplied transport securing devices.
Secure all parts against shifting and damage.
No direct sunshine
No strong draught
No excessive temperature fluctuations
Temperature range –10 °C to +40 °C.
3.6 Levelling
Only a weighing platform which is aligned exactly horizontally supplies exact weighing results. The weighing platform has to be levelled during the initial installation and
whenever its location is changed.
As the spirit level is underneath the weighing plat-
form it has to be removed.
Level balance with foot screws until the air bubble of
the water balance is in the prescribed circle.

4 Operating limits
The weighing platform is designed so robustly that an occasional exceeding of the
maximum weighing load does not lead to damage.
The static bearing capacity, i.e. the maximum permissible load, depends on the type
of load carrying (position A – C). The maximum static bearing capacity may not be
exceeded.
Avoid falling loads, shock loads as well as impacts from the side.

Clean the weighing platform with a soft cloth soaked with a mild cleaning agent.
Take off the load panel and remove any dirt and foreign substances which may
have collected underneath it. Do not use any hard objects to do so. Do not open
the weighing platform.
