Balance zero display
Environmental influences can lead to the exact figure of “

“ not being displayed
in spite of an empty weighing dish. It is, however, possible to reset your balance to
zero at any time and thus ensure that weighing really does commence at zero. Set-
ting to zero when a weight is applied is only possible within a certain type-dependent
range. In the event that the balance cannot be reset to zero with an applied weight,
this range has been exceeded.

Operation
Display
If the balance does not show exactly zero
although the pan scale is unloaded, press the
-button and the balance will be reset to
zero.
After a brief waiting time your balance is
reset to zero.
In addition to this, the sign for the balance
zero setting will be displayed

6.9 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 for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To re-
ceive accurate measuring values it is also recommended to adjust the balance peri-
odically in weighing operation.
6.9.1
Adjustment with external weight (only FES)
Procedure when adjusting:
Observe stable environment conditions. A warming-up time (see cap. 1) for stabilisa-
tion is necessary. Ensure that there are no objects on the weighing plate.
At verified balances, the adjustment is locked by a switch. In order to adjust, open the
locking switch see chap.6.11.
