OVERVIEW
Interface to the Xi for setup, calibration and diagnostics can be via a 375/475
Field Communicator or Asset Management System.
Setup, calibration and diagnostic operations will differ depending on the
selected interface for communications with the transmitter.
STARTUP
The O
2
Probe will take approximately 45 minutes to warm up to the 736
°
C
heater setpoint. The 4-20 mA signal will remain at a default value of 3.5 mA
through this warm-up period. Once warm, the O
2
probe will be reading
oxygen, and the 4-20 mA signal will be reading based on the default range
of 0-10% O
2
.
NOTE
The Xi offers optional advanced features such as elevated process
temperature capability to 800
°
C, autocalibration via an SPS solenoid box, a
stoichiometer feature for indicating the level of oxygen deficiency in reducing
conditions, and programmable reference to enhance accuracy at near
ambient levels of O
