Select "AUTO 2 RANGES" (Automatic two range transfer) in parameter
number "B10".
Forward second range can be set by calling up parameter No. B33 .
Setting restrictions: First range
≤
2nd range.
Further second range span should be set in the same number of places of decimals
as first range span in parameter No. B03 .
Example: First range : 1.000 then second range should be
4.000
Hysteresis width at switching range can be set in parameter No. B34 .
It is the rate (%) of first range span.
