7.1.4 Universal Input Resistance Measurement 1-8 (30103,
30104-30117, 30118)
In these 16-bit registers the result is expressed in
Ω
or in 0.1
Ω
units for PT1000 and
NI1000 configuration. In the register with the lower number, it is the lower storage part of
the result and the higher register storage part of the result.
7.1.5 Universal Input Configuration 1-8 (40151-40158)
These 16-bit registers are used to configure universal inputs in accordance with the
following table:
