5.1.5 Operation access authorisation
To protect the transmitter against an unintended or undesired change in the
configuration and calibration data, functions can be protected using four-digit access
codes.
Access authorisation has the following levels:
Display level (accessible without a code):
The complete menu can be viewed. The configuration cannot be altered. No calibration
is possible. On this level, only the control parameters for new processes can be
changed in the "DIAG" menu branch.
Maintenance level (can be protected by the maintenance code):
This code allows access to the calibration menu.
Use this code to operate the temperature compensation item. The factory functions and
the internal data can be viewed.
Factory setting Code = 0000, i.e. the levels are not protected.
In case you have mislaid/forgotten the supplied maintenance code, contact your E+H
service office.
Specialist level (can be protected by the specialist code):
All menus can be accessed and changed.
Factory setting Code = 0000, i.e. the levels are not protected.
In case you have mislaid/forgotten the supplied specialist code, contact your E+H
service.
To activate the codes (= functions locked) see the item "PARAM"
codes" (s. page 33). Enter your desired codes here. If the code is activated, you can
only edit the protected areas with the rights mentioned above.
