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 O2 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 O2probe will be reading oxygen, and the 4-20 mA signal will be reading based on the default range of 0-10% O2.

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 O2.
