3.3.2 Editing TEDS in the Template view
The Template view uses the definitions in the Standard IEEE 1451.4 and
displays the entered values in the same way that they are stored in the TEDS
memory. The main templates for use with HBM transducers are listed in the
following chapter. This includes, in addition to the templates defined in the
Standard IEEE 1451.4, those that have been supplemented in definition by
HBM based on the standard.
The Template view displays the structure of the TEDS memory on the left
screen side in the form of a tree structure. If you click in this diagram on the
icon for the basic memory (Basic TEDS) or one of the subordinate icons for
individual templates, these are shown on the right screen side in table form.
The table entries can then be easily edited. Editing options are restricted
when working with user rights in the hierarchies USR (operator) or CAL
(calibrator).
When creating completely new TEDS contents, the individual templates must
first be generated via the command sequence ”Edit” – ”New” – ”New
template”. The minimum requirement is at least one template created that
describes the respective transducer type (e.g. ”Bridge Sensor” for SG-based
transducer). Supplementary optional templates (e.g. ”HBM Channel Name”,
”Calibration Curve”) can be added at any time (please note the information on
Page 10).

The main templates
The following detailed information about the content of individual TEDS
templates is to facilitate writing of TEDS contents in the Template view (see
Chapter 3.3.2 ). This procedure is however generally not necessary. Most
entries can be made more easily via the self-explanatory input fields in the
HBM view (see Chapter 3.3.1 ).
All the terms and expression in a template are in English, since they are
defined in this language only in the IEEE 1451.4 standard.
Occasionally the number of bits specified by the standard is so low that the
numeric values entered cannot be adopted exactly.
Additions for units of measurement such as m (for milli-...), k (for kilo-...), u
standing for
µ
(micro-...) etc. are in the value column, not the unit column.
