6.3 Battery operation and change
In order to save the battery, the balance switches automatically off after 30 seconds
without weighing.
If the balance is not used for a longer time, take out the batteries and store them
separately. Leaking battery liquid could damage the balance.
6.4 Initial Commissioning
The warm-up period after the start stabilises the measured values.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter “Adjustment”.
6.5 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
location and variation of surrounding temperature. To receive accurate measuring
values it is also recommended to adjust the balance periodically in weighing
operation.
6.6 Adjusting
With an adjustment weight, the weighing accuracy can be checked and re-adjusted
at any time.
Procedure when adjusting:
Observe stable environmental conditions.
 Switch on scale by and wait for “0.0“ to appear
on the screen
 Press and hold until “ZERO“ appears flashing
 Confirm by pressing and the value of the
adjustment weight will be shown flashing
 Position the adjustment weight; after a while “PASS“
appears; this concludes the adjustment process.
Afterwards the scale switches off automatically.
