4.3 Optional templates
In addition to the essential templates required for describing the transducer,
the Standard IEEE 1451.4 also provides for optional templates which allow
the opportunity to store further information about the transducer in the TEDS
memory. Further optional templates can be provided manufacturer-specific by
HBM.
HBM template: Signal Conditioning
When the transducer manufacturer (or user) creates the template, a definition
is entered about the possible settings for which entries may be stored in the
TEDS memory. As an example it is possible to create the template in such a
way that the only value which may be stored in TEDS is the cut-off frequency
for the lowpass filter.
This has the advantage for users who prefer to carry out a manual zero
balance that the Zero Compensation Value parameter will not be overwritten
next time the TEDS memory is imported.

Lowpass Filter Frequency 1.000 Hz USR If the TEDS memory contains values
which the measuring amplifier can-
not adopt - because filter settings
are only possible in certain fre-

is set up.
