Performing a digital zero trim (option DZ)
A digital zero trim (option DZ) provides the same function as a zero/lower sensor trim, but can be
completed in hazardous areas at any given time by simply pushing the zero trim button when the
transmitter is at zero pressure. If the transmitter is not close enough to zero when the button is pushed,
