9.3.6.2 Certification data log
The certification data log is activated by default but can be deactivated as an option. The
parameters affected are then below the calibration lock.
Using the certification data log in accordance with PTB-A 50.7, some calibration law-relevant
parameters can also be changed when the calibration lock is closed. The requirements for this
are:
•
The administrator lock must be opened (see below).
•
At least three free entries must be available in the certification data log.
The parameters affected according to the factory settings are:
•
CP.I1 cp value for input 1,
•
MPer measurement period
•
Md.K K number mode
•
Clr.A delete measurement archive
•
Md.I1 mode for input 1
•
QMax maximum load (plausibility check in encoder mode)
For every change of a parameter under CDL with a closed calibration lock, a data row for the
value is entered before and after the change.
If the certification data log is full, it can be deleted when the calibration lock is open using the
ClCDL command. (see section 6.3.1.13)
If the calibration lock is opened while the calibration logbook is open, it can only be
closed again after deleting the certification data log.
9.3.6.3 Administrator lock and customer lock

but that should not be changed without authorization.
The locks can be opened by entering a code (the "key") under Cod.A or Cod.C and closed by
entering "0" for St.AL or St.CL.
These values can be found under the path:
Admin Device settings Access or
