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 Instruction manual MBC
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
under http://www.kern-sohn.com

Observe stable environmental conditions. For warm-up time required for
stabilisation see Instruction manual MBC chpt 1.
Access to service menu „tCH“is
locked in verified balances.
To disable the access lock, destroy the seal and actuate the adjustment
switch. Position of the adjustment switch see nstruction manual MBC chap.
13.
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.
