Interference frequency for 4-channel mode is "All"
1)
Interference frequencies 50/60/400 Hz are designated as "All"
2)
Series-mode rejection for 8-channel mode is reduced as follows:
3)
50 Hz > 70 db
60 Hz > 70 db
400 Hz > 80 dB
50/60/400 Hz > 90 dB
In 4-channel mode, the converted value tunes to 100% within 80 ms. The value
4)
established in this process is set every max. 10 ms.
