6. Press Down key to select COe Out Tracks. Select Yes or No to determine if
the transmitter will update the COe lock value.
7. Press Down to select O2 Cal Interval. Enter the amount of time in days and
hours that is desired between automatic calibrations.
8. Press Down key to select O2 Next Cal. Enter the amount of time in hours
until the next automatic calibration. Press Left three times to move back to
the LOI operating display.
6.2.2 Set up autocalibration using HART
®
Use the following procedure to specify a time interval (in hours) at which the
transmitter will automatically calibrate.
Note
Automatic calibration is only available on transmitters equipped with calibration
solenoids.
Procedure
1. From the DEVICE SETUP screen, select DETAILED SETUP.
2. From the DETAILED SETUP screen, select O2 CALIB PARAMS or COE CALIB
PARAMS.
3. If the transmitter is equipped with calibration solenoids and you want timed
automatic calibrations, select Solenoids; then select Yes. Select No to
disable the calibration solenoids.
4. Select O2 CalIntrvl (O
2
calibration interval) and enter the desired time in
hours between automatic O
2
calibrations. Select COE Callintrvl and enter
the desired time between automatic COe calibrations. To disable automatic
calibration for O
2
and COe, enter 0 for both CalIntrvl parameters.
If you want, you can change the O2 NxtCalTm and the COeNxtCalTm (next
calibration time) parameters to synchronize a calibration at a specific day or
time.
CAUTION
When setting automatic calibration times, set CalIntrvl and NxtCalTm so that O
2
and COe are NOT calibrated simultaneously.
Note
To select a menu item, either press Up and Down to scroll to the menu item and
press Right or use the number keypad to select the menu item number.
To return to a preceding menu, press Left.
5. From the O2 CALIB PARAMS screen, select CalIntrvl (O
2
calibration interval).
6. At the prompt, input a time interval (in hours) at which an automatic O
2
calibration will occur and press ENTER.
7. From the DETAILED SETUP screen, select COE CALIB PARAMS.
8. From the COE CALIB PARAMS menu, select CalIntrvl.
