7.5 Initial start-up
A warm-up time of 5 minutes stabilises the measured values after switching on.
The accuracy of the balance depends on the local acceleration of the fall.
Please be sure to observe the information in the chapter on adjusting.
7.6 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance 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 balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out during the initial start-up, after change in lo-
cation and variation of surrounding temperature. It is also recommendable to adjust
the balance periodically during weighing operation in order to obtain exact measured
values
7.7 Adjusting
Balance accuracy can be checked and adjusted at any time using an adjusting
weight.
Method of adjusting:
Observe stable ambience conditions. A short warming-up time of approx. 5 minutes
for stabilisation purposes is useful.
Press UNIT key and hold depressed until the exact size of the adjusting weight
flashes on the display panel, “Load” appears on the display panel alternately.
Place the adjusting weight in the centre of the weighing plate. Press UNIT key.
The value of the size of the adjusting weight will stabilise a short time later.
Keep the adjusting weight next to the balance. A daily balance accuracy check is
recommended for applications relevant to quality.
