Operation 67
6.3.6.2 Certification data log
The certification data log is activated as standard but can also be disabled.
The corresponding parameters will then be protected by the calibration
lock.
Using the "certification data log" as per PTBA 50.7, several parameters
subject to calibration regulations can also be adjusted when the calibration
lock is closed. This is subject to the following conditions:
The administrator's lock (see below) must be open.
There are at least three free entries in the certification data log.
The following parameters are set as default:
"CP.I1" cp value for input 1
"MPer" measurement period
"Md.K" K-factor mode
"Clr.A" delete measurement archive
"Md.I1" mode for input 1
"qMax" maximum flow (plausibility check in encoder mode)
For every change of a parameter listed under "CDL" when the calibration
lock is closed, one row of data will be entered for the value before and after
the change.
If the certification data log is full, it can be deleted using the command
“ClCDL” if the calibration lock is open (see chapter 5.3.1.16).
If the calibration lock is opened when the certification data
log is full, it can only be closed again after the certification
data log has been deleted.
6.3.6.3 Administrator and customer locks
Administrator and customer locks are used to protect data which is not sub-
ject to calibration regulations, but which should also not be modified without
authorization.
These locks can be opened by entering a code (i.e. the "key") under
“Cod.A” or “Cod.C” and are closed by entering "0" for “St.AL” or “St.CL” .
These values can be found under the following path:
Admin Device settings Access
or Serv. Device settings Access
A time (in minutes) can also be set here for each lock, after which it will au-
tomatically close.
