4 Startup and operation
4.1 Overview
Interface to the Rosemount Xi for setup, calibration, and diagnostics can be via a Field
Communicator or Asset Management System.
Setup, calibration, and diagnostic operations differ depending on the selected interface
for communications with the transmitter.
4.2 Startup
The O
2
probe takes approximately 45 minutes to warm up to the 1357 °F (736 °C) heater
setpoint. The 4-20 mA signal remains at a default value of 3.5 mA through this warmup
period. Once warm, the O
2
reads oxygen, and the 4-20 mA signal's reading is based on the
default range of 0-10% O
2
.
NOTICE
The Rosemount Xi offers optional advanced features, such as elevated process
temperature capability to 1472 °F (800 °C), autocalibration via an SPS solenoid vox, a
stoichiometer feature for indicating the level of oxygen defiency in reducing conditions,
and programmable reference to enhance accuracy at near ambient levels of O
