OPERATOR - INITIATED AUTOCALIBRATION

MANUAL CALIBRATION

An operator can initiate an automatic calibration at any time provided that the unit is equipped with calibration solenoids.

Autocalibration using HART

To initiate an automatic calibration using HART/AMS, perform the following steps on the HART menu tree. Refer to Section 4, Using HART Communications, for the HART menu tree.

1.Select DIAG/SERVICE from DEVICE SETUP menu.

2.Select CALIBRATE from the DIAG/SERVICE menu.

3.Select PERFORM CAL from the CALIBRATE menu.

4.Select CAL METHODS from the PERFORM CAL menu.

5.From the CAL METHODS menu, select the type of calibration desired: O2 Calibration, COe Calibration, or O2 and COe Calibration.

If a unit is not equipped with calibration solenoids, a calibration must be performed by an operator following prompts from the unit. Refer to the following paragraphs for manual calibration.

Manual O2 Calibration using HART

To perform a manual O2 calibration using the HART communicator or AMS, use the following procedure. If necessary, refer to Section 4, Using HART Communications, for the HART menu tree.

NOTE

To select a menu item, either use the up and down arrow keys to scroll to the menu item and press the right arrow key or use the number keypad to select the menu item number.

To return to a preceding menu, press the left arrow key.

1.From the DIAG/SERVICE menu, select CALIBRATION. From the CALIBRATION menu, select PERFORM CAL.

2.From the PERFORM CAL menu, select CAL METHODS. Select O2 CALIBRATION to start O2 calibration.

3.In the first O2 Calibration screen, a Loop should be removed from automatic control warning appears. Remove the OCX 8800 from any automatic control loops to avoid a potentially dangerous operating condition and press OK.

4.The main Calibration screen should look like the following. Press OK to continue.
