First isolate HP side of Tx. and open vent port of HP side.
LP Side fill service liquid up to LP tapping and set the
zero.
In this case your HP & LP both sensor working or not it was
clearly identified.
While applying span pressure on LP side in this case if HP
side sensor fails than transmitter will not work after zero
checking.
