7. Using the Command % option in the T

UNE

menu, enter a 100

percent command and verify that the position follows to
within 0.5 percent.

8.

If the unit fails either of the tests above, perform a Stroke
calibration in the C

ALIBRATE

menu.

9. Use the S

TATUS

menu and set the Row Two variable to be

“ISA upstream pressure.”

10. Verify that the unit is correctly indicating the ambient

pressure.

11. Use the S

TATUS

menu and set the Row Two variable to be

“ISA downstream pressure.”

12. Verify that the unit is correctly indicating ambient pressure.

13. If the unit fails the above tests, re-zero the transducers using

the P1 & P2 option in the C

ALIBRATE

menu. You may also

need to pressurize the sensors and verify the Span if the
calibration is suspect.

14. Use the S

TATUS

menu and set the Row Two variable to be

“process temperature.”

15. Verify that the unit is correctly indicating ambient

temperature.

16. If the unit fails the above test, re-calibrate the transducer

using the thermocouple option in the C

ALIBRATE

menu. (This

calibration requires a Type-K thermocouple simulator or a
temperature bath.)

17. Use the C

ALIBRATE

menu to check the analog channels that

you will be using.

18.

Finally, use the T

UNE

menu to select the process variable

that you will be controlling and set the range.

Putting the Unit on line - After installing the unit, use the T

UNE

menu to configure the setpoint signal to the proper source for your
DCS system. If you will be using the system in the Automatic mode,
adjust the Proportional-Integral-Derivative (PID) parameters so the
loop responds satisfactorily.

Backing up the system - When you have your unit calibrated and
working according to your needs, back up the configuration into the
safe memory area. This is done in the Save Backup choice in the
Tech option of the C

ONFIGURE

menu.
