Yes there are two adjustments in transmitter and
positioners i.e ZERO and SPAN adjustment.
For example, if we calibrate the level transmitter for 4 to
20 mA with the range of 0 mmH2o to 5000 mmH20, for 0 mmH2o
we must get 4 mA and if it not 4 mA(say 4.5mA) means, we
start to adjust the zero adjustment to make 4 mA for 0
mmH2o.
And for 5000 mmH2o we must get 20 mA and if it not 20 mA
(say 19.69 mA) means, we start to adjust the span to 20 mA.
This is the way to calibrate the transmitter with the help
of zero and span adjustment.
