For transmitter
1)4MA value is Low range value(ie zero percentage)
2)20MA value is upper range value(ie 100 percentage)
3)but span means the difference between the LRV and URV

Example for span

if the range 0 to 100 the span is 100 and the zero value =0.
if the range -100 to 100 the span is 200 and the zero value=-100.
