READY
The PV Bias calibration procedure allows you to align the "zero" of
the process with the "zero" reading of the transmitter. This may be
done in one of two ways:
Apply a pressure that corresponds to the desired zero offset or
bias [SET PV ZERO]
To scale to a value different from zero, calculate the offset or
biasand apply it to the 600T EN [SET PV VAL]
Display
This operation will cause a change in output not cor-
responding to the input. Be sure the control loop is in
manual.
Select YES.
