12 TEDS
TEDS (Transducer Electronic Data Sheet) allows you to store the transducer
data (characteristic values) in a chip, that can be read out by a connected
measuring instrument.
There are two TEDS blocks in the T12 digital torque transducer:

TEDS 1 (torque): a choice of voltage sensor or frequency sensor/pulse
sensor

TEDS 2 (rotational speed/angle of rotation): frequency sensor/pulse sensor
The data are written automatically into the TEDS blocks by the T12 Assistant,
when the parameters are stored. The same menu is used to select whether
the device should be presented as a voltage sensor or as a frequency sensor
or as a frequency or pulse sensor. A template is also stored, which provides
the conversion factors for the different physical units.
The T12 is a transducer, that is to say, the T12 does not read the TEDS
blocks, it only writes them. (We therefore strongly advise against editing the
values with the HBM TEDS Editor, for example!)
You can read the data of the TEDS block with the TEDS Editor.
Important
To ensure that the data of the TEDS blocks correspond to the properties of
the T12 torque transducer, you must not overwrite the information from the
measuring amplifier.

Content of the TEDS memory as defined in IEEE 1451.4
The information in the TEDS memory 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 amplifier
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 three areas:
Area 1:
An internationally unique TEDS identification number (cannot be changed).
