Answer / mithilesh kumar
zero elevation.
when TX range is -100 to +100 mmwc.
during calibration tx shows 0(zero).it's called zero
elevated.
ie. when we get zero value which is greater than LRV.
Zero Suppression:
when TX range is 20 to 100 mmwc.
during calibration TX shows 0(zero) value.it's called as
zero suppression.
ie. when get zero value but it's below of LRV.

ZERO ELEVATION MEANS WHITE FIXING THE TRANSMITTER LOWER
THAN THE PROCESS LINE IT GOES NEGATIVE .TO CHANGE FROM

ZERO SUPPRESSION IS WHILE FIXING THE TRANSMITTER ABOVE THE
PROCESS LINE IT SHOWS ABOVE 4MA THEN WE ADJUST TO 4MA
