Content Of The Teds Module As Defined In Ieee 1451.4 - HBM CMA Series Operating Manual

Start‐up
This level concerns entries that a calibration laboratory must be able to
change, if, for example, the sensitivity in a TEDS module has to be updated
after recalibration.
3. Administrator rights (ID level)
Administrator rights in relation to TEDS are needed by the sensor
manufacturer. In the case of a self‐built sensor or subsequent upgrading
with TEDS, HBM customers can of course also make use of these rights.
Different user rights are needed in order to amend the entries in the so‐called
"templates", and these rights may differ from one entry to the next within a
template. However, the software must also support rights management,
otherwise all the entries would be accessible during later use (the hierarchy of
rights specified in the TEDS standard is not monitored by the TEDS module,
and not every software package supports rights management).

Content of the TEDS module as defined in IEEE 1451.4

The information in the TEDS module is organized into areas which are
prestructured to store defined groups of data in table form. Only the entered
values are stored in the TEDS memory itself. The evaluating electronics
firmware assigns the interpretation of the respective numerical values. This
places a very low demand on the TEDS memory. The memory content is
divided into 3 areas:
Area 1:
An internationally unique TEDS identification number (cannot be changed).
Area 2:
The base area (basic TEDS) with a configuration defined in standard IEEE
1451.4. The transducer type, the manufacturer and the transducer serial
number are contained here.
Area 3:
Data specified by the manufacturer and the user are contained in this area.
The physical measurand and the physical unit are also defined when the
