1 Introduction
Thank you for purchasing a KERN WTB scale. These scales are rugged, simple to operate, and can be
used without connection to an external power supply. The scale has a menu system which allows it to
be adapted to your needs.
Please read through these Operating Instructions carefully, and always follow them!
1.1 Safety and the environment
– Read through these Operating Instructions carefully, even if you already have ex-
perience of KERN scales. Only ever use your scale as described in the Operating
Instructions. Be sure to follow the instructions for putting your new scale into
operation.
– Do not use the scale in a explosive environment.
– For connection to the power supply use only the AC adapter delivered with the scale.
Before you connect the scale to the power supply check that the voltage stated on the
AC adapter is the same as the local power supply voltage. If it is not, do not connect
the AC adapter under any circumstances but contact your dealer.
– Although your scale is very ruggedly constructed, it is nevertheless a precision
instrument. Impacts to the weighing pan, or placing excessively heavy loads on it, can
damage the scale.
– Observe local and national environmental regulations when disposing of the scale.
The scale is fitted with a storage battery that contains heavy metals. Do not dispose
of the battery as normal waste! Observe local regulations for disposal of environmen-
tally harmful substances.

Selecting a location

Selecting a suitable location makes a decisive contribution to precise measurement results
and lengthens the service life of the scale:
– Choose a stable, vibration-free surface which is as horizontal as possible.
– Ensure there are no excessive fluctuations in temperature, and no direct sunlight.
– Make sure that the environmental conditions are met (Chapter 9.1).
– Avoid drafts (e.g. from fans or air conditioning).
– After any major change of geographical position, the scale should be newly adjusted
(calibrated) (Chapter 4.3).
