An adjusting step corresponds to 20 µA. The complete adjusting range is ± 0.62 mA (31 steps). If the
adjusting range does not suffice, change to display F32 or F33 by pressing ENTER when display shows F32
31 or F33 31, press ENTER again and continue adjusting at F32 00 or F33 00.
3 wire connection:
At this the ranges 0-20 mA and 4-20 mA are possible. At a switch over between the two ranges with F31 the
current output is automatically adjusted at equipment as of firmware version 1.4 . (s.F 61). A perhaps
necessary fine adjustment can be carried out with F32 or F33.
2 wire connection:
At this only the range of 4-20 mA is meaningful. The range of 0-20 mA is not closed however. At the change
to 0-20 mA with F31 the equipment assumes a remodelling on 3 wire connection and the current output is
adjusted according to this. A perhaps necessary fine adjustment can be carried out with F32 or F33.
WARNING
Since YOKOGAWA doesn’t have any influence on the custom-designed connection the current output is not
automatically adapted, if the connection is changed from 2 wire to 3 wire or vice versa .This must be manually
carried out with the functions F32 and F33.
