You should always try to do a regular calibration before resorting to a
primary calibration in all cases except when you install a new cell. If a
regular calibration doesn’t work correctly, see the Calibration Checks
section in the Troubleshooting chapter for possible calibration setup
problems affecting the calibration. If these checks have been made and
the system still can’t be properly calibrated you should perform a
primary calibration.
Setting Up a Primary Calibration
Make sure you have properly entered your calibration gas values using
the Cal Gas Values option from the Calibrate Key before starting your
primary calibration.
1. Select Primary Calib from the Setup Key.
2. If you have the auto calibration card option (and a remote calibration
unit), you will be prompted to select Auto Calibrate, Remote Calibrate,
or Manual Calibrate. If you don’t have the auto calibration option,
you will be placed into a manual calibration where you will be told to
inject your span gas into the calibration gas inlet port.
From this point, operations work as they do for a regular calibration.
Once the primary calibration is complete, the system will notify you that a
standard calibration is required by displaying a Calibration Required mes-
sage. Oxygen readings on the display will not be accurate until the regular
calibration is performed. In addition, a 15-minute recovery time follows
the thermal calibration to allow the cell to stabilize. Wait an additional 45
minutes, then perform a regular calibration.
During the recovery time immediately following the primary calibration,
you may see some temperature-related error messages. You can ignore
these messages and assume no problem exists. The cell temperature is
adjusted after a primary calibration.
