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, the command may fail due to excess correction. If ordered, a Digital Zero Trim
can be performed by utilizing external configuration buttons located underneath the top tag of
the transmitter, see
for DZ button location.
1.
Loosen the top tag of the transmitter to expose buttons.
2.
Press and hold the Digital zero button for at least two seconds, then release to perform
a Digital Zero Trim.

trim of an absolute pressure unit or inaccurate pressure source.
