14 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.
Prepare the required adjustment weight. The adjustment weight to be
applied depends on the capacity of a weighing scale, see chap. 1.
Carry out adjustment as closely as possible to admissible maximum
load of weighing scale. Information about test weights you will find in
the internet unde
Observe stable environmental conditions. For warm-up time required
for stabilisation see chap. 1.
The adjustment function is locked for verified balances.
To disable the access lock, destroy the seal and actuate the adjustment
switch. Position of the adjustment switch see chap. 11.
Attention:
After destruction of the seal the weighing system must be re-verified by an
authorised agency and a new verification wire/seal mark fitted before it can
be reused for applications subject to verification.
