as 2-wire transducer
as 4-wire transducer
1) Interference frequency for 4-channel mode is "All"
2) Interference frequencies 50/60/400 Hz are designated as "All"
3) The series mode rejection in 8-channel mode is reduced as follows:
50 Hz > 70 db
60 Hz > 70 db
400 Hz > 80 dB
50/60/400 Hz > 90 dB
4)
In 4-channel mode, the converted value settles to 100% within 80 ms. The value determined in this process is returned
at intervals of max. 10 ms.
