0 % = (-45) PSI = 4 mA
25%= (-22.5) PSI= 8 mA
50%= 0 PSI = 12 mA
75%=22.5 PSI = 16 mA
100% 45 PSI = 20 mA

Calculation :
LRV = (-45) PSI
URV = 45 PSI
SPAN = URV - LRV = 45-(-45) = 90
Calculate % of SPAN for e.g. 0 PSI is {(0-(-45))/SPAN}*100 = (45/90)*100 = 50% of SPAN
mA= [{(% of SPAN)/100}*16]+4 or in other terms ...
1% of SPAN = 4+0.16 = 4.16 mA
2% of SPAN = 4+0.32 = 4.32 mA
3% of SPAN = 4+0.48 = 4.48 mA
.

.
.
50% of SPAN = 4 + 8 = 12 mA
.
.
.
100% of SPAN = 4 + 16 = 20 mA


Hope this will be helpful to you.
