The use of TEDS is not yet supported by the current firmware version.
It will be in one of the future versions however.

Important: Connect the sense leads to the corresponding excitation
voltage leads by wire bridges (2 at 2' and 3 at 3') if you are not using
a 6-wire configuration (with 5 wires assigned). Otherwise a sensor er-
ror will be signaled, and you will not be able to measure (invalid mea-
sured value).
