8.2 Overview verified weighing systems
(contacts of circuit board [K1] short-circuited by means of jumper)
In verified weighing systems the access to „P2 mode and „P4 tAr“ is locked.
KERN KFB-TM:
To disable the access lock, destroy the seal and actuate the adjustment switch.
Position of the adjustment switch see chap. 6.11.
KERN KFN-TM:
In order to unlock the access, the seal must be destroyed and both contacts of the
printed circuit board [K2] must be short-circuited by a jumper, see chap. 6.11.
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.
