Adjustment - KERN EOC 30K-4S Operating Manual

6.8 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected weighing plate must be coordinated - in compliance
with the underlying physical weighing principle - to the existing acceleration due to
gravity at its place of location (only if the weighing system has not already been
adjusted to the location in the factory). This adjustment process must be carried out
for the first commissioning, after each change of location as well as in case of
fluctuating environment temperature. To receive accurate measuring values it is also
recommended to adjust the display unit periodically in weighing operation.
•
In weighing systems with a resolution of < 15 000 dividing steps an
adjustment is recommended.
In weighing systems with a resolution of > 15 000 dividing steps a
linearisation is recommended (see chap. 6.10).
•
Prepare the required adjustment weight. The adjustment weight to be
used depends on the capacity of the weighing system. Carry out
adjustment as near as possible to the weighing system's maximum
weight. Info about test weights can be found on the Internet at:

•
Observe stable environmental conditions. Stabilisation requires a certain
warm-up time.
