Suppose the range of process variable is
(0-150)PSI.So when the input is zero,the value in
instrument,say a transmiter connected to measure the
pressure,will shows 4mA.This is live zero.i.e,even if the
input is zero,output has some value.
Lets assume the instrument is faulty or the
power supply to the instrument is cuts off.Then it will
show zero reading.This is called dead zero.i.e,when the
instrument is faulty,it will shows the real zero value.
