What is Zero suppression & Zero Elevation?

Zero suppression & Zero elevation are values that correspond to the 4-20mA transmitter range for level measurement using Differential pressure transmitter (DPT). In signal conditioners, in particular, zero suppression and zero altitudes relate to a reduction (deletion) or angle (altitude) of the nominal “zero” yield so that it is not at zero volts (or milliamps). …
