Calibration
6.1
Overview
During calibration, the operator applies two calibration gases with known O
concentrations and one calibration gas with a known COe concentration to the
transmitter. Slope and constant values are calculated to determine if the
transmitter is correctly measuring net concentration of O
the industrial process.
Before calibrating the transmitter, verify that the calibration gas parameters are
correct by setting the test gas values to use when calibrating it. Refer to
Configuration and
There are three calibration methods available to the transmitter: automatic,
operator-initiated, and manual. You can access calibration commands and menus
with the Field Communicator or the optional local operator interface (LOI).
6.2
Fully automatic calibration
If the transmitter is equipped with calibration solenoids, you can program it to
automatically calibrate without any operator action.
