5.1 Cable extension

Extension cables must be shielded and of low capacitance. The supply lines in
particular should have large cross‐sections.
HBM recommends and supplies extension cables and measurement cables by
the meter.
With cable extensions, you must make sure that there is a proper connection
with minimum contact resistance and good insulation between leads and
ground. This is why all the connections should be soldered, made at least with
secure, stable terminals and given a waterproof routing. In the open air and in
a damp environment, the terminal boxes should be encapsulated.
If ordered so that is already a longer cable attached to the transducer when it
leaves the factory, then this, like the 3 m long standard cable is included in the
calibration.
Measurement cables should not be routed parallel to power lines and control
circuits (in shared cable pits, for example). If this cannot be avoided, protect
the measurement cable with a rigid steel conduit and keep it at least 50 cm
away from the other cables. Avoid stray fields from transformers, motors and
contact switches.

5.2 TEDS transducer identification

TEDS stands for "Transducer Electronic Data Sheet". An electronic data sheet
is stored in the transducer as defined in the IEEE 1451.4 standard, making it
possible for the measuring amplifier to be set up automatically. A suitably
equipped amplifier imports the transducer characteristics (electronic data
sheet), translates them into its own settings and measurement can then start.
HBM provides you with the TEDS Editor for storing your data. This is included
in the software for the MGCplus Setup Assistant.
The Editor also makes it possible to manage the different user rights to protect
the fundamental transducer data from being inadvertently overwritten.
Contents of the TEDS memory as defined in IEEE 1451.4:
The information in the TEDS memory is organized into templates 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.
