Every access party has a lock and a matching key.
The access rights apply for both inputs by keyboard and for access via the optical, electrical
(fixed-wired) or integrated modem interface. If the lock is closed, all attempts to set values
prompt a corresponding error message (see chapter 6.3.5, Error messages when entering
values).
Reading values via the interfaces is also only possible within the meaning of data protection if
a lock is open.
6.3.6.1 Calibration lock
The calibration lock serves to secure calibration law parameters. These include all values
that influence volume counting and volume conversion.
The calibration lock is designed as a key that is placed within the EK205 housing below the
circuit board cover. It can be secured with an adhesive label (see chapter 5.3.1.1, Opening
the
calibration lock
).
The calibration lock is opened by actuating the key (the P symbol flashes in the display) and
closed again by actuating it a second time (P symbol extinguishes). Closing is also possible
by deleting the St.ES value (see chapter 6.4.6, Strg. tab (control)) via the keyboard or
interface. Using the enSuite software, it is also possible to set a time in minutes after which
the calibration lock closes automatically.
In particular for applications outside the German calibration obligation or the MID, the
protection degree of all parameters can be changed on request.
As such, parameters that are below the calibration key by default can also be protected with
the administrator key or calibration logbook.
