0x46(Zero adjusting), 0x47(Span adjusting)
Zero adjusting , Span adjusting
Zero adjusting (hereinafter referred to as F_1) corresponds to set the
minimum pressure, Span adjusting (hereinafter referred to as F_2) to set
the maximum pressure. F_1 and F_2 have setting ranges of 0-90%F.S.
and 10-120%F.S., respectively. However, the set pressure exceeds
rated output; 100％F.S. is out of warranty. (refer to Fig.2,3)
The values are necessary to satisfy "F_1 + 10%F.S. < F2". If not, the
previous values are reflected in this function.
Default of Zero adjusting: 0x0000
