The amplifier firmware assigns which template is to contain which data, and
the interpretation of the respective numerical values. This means that the
memory requirement for the TEDS module is very low. All the TEDS tem­
plates are in English.
The memory content is divided into three areas:
Area 1:
An internationally unique TEDS identification number (cannot be changed).
Area 2:
The base area (basic TEDS), to the configuration defined in standard IEEE
1451.4. The transducer type, the manufacturer and the transducer serial num­
ber are contained here.
Area 3:
Data specified by the manufacturer and the user are contained in this area.
HBM has already written the Bridge Sensor template for U93 force transduc­
ers. The physical measurand and the physical unit are also defined when the
template is created.
The available unit for the particular measurand is specified in the IEEE Stan­
dard. For the measurand of force, this is the unit N.
The resolution of the characteristic values mapped in TEDS (characteristic
curve of the transducer) must also be selected when the template is created.
HBM always opts for "Full Precision" here, in order to be able to use maxi­
mum digital resolution. This choice is also recommended to users who pro­
gram the TEDS module themselves.
