Configuration and Use Manual
Navigate to the Density Offset Calibration wizard: OFF-LINE MAINT > OFF-LINE CAL >
DENS CAL OFFSET and activate Select.
If concentration measurement is enabled, the active matrix is displayed. Activate
Scroll to continue. The current reference temperature is displayed.
Activate Scroll to move to the next step.
Enter the laboratory reference density and save it to the transmitter.
Activate Select to apply the offset, and wait for a few seconds while the calibration
process is performed.
If the calibration succeeded, the calculated density offset is displayed.
If the calibration failed, Density Offset is reset to the original value.
• Verify your laboratory reference value.
• Ensure that your process was stable during the entire procedure.
• Repeat the calibration.
Activate Scroll to view the referred density value.
• For concentration measurement, Referred Density (Concentration) is displayed.
• For API referral, Referred Density (API) is displayed.
To exit the calibration, activate Scroll, then activate Select.
Read Section 9.6 if you have not done so already.
Navigate to the Density Offset Calibration wizard: Device Tools > Calibration > Density
Offset > Density Offset Calibration.
Enter the laboratory reference value for density.
Click Apply Offset and wait for a few seconds while the calibration process is
performed.
For API referral: Check the values displayed in the Density Offset and Referred Density
(API) fields.
If the calibration succeeded:
• Density Offset displays the updated value for this parameter.
• Referred Density (API) shows this process variable with the new density offset
applied. This value should match the laboratory reference value.
If the calibration failed, Density Offset is reset to the original value.
• Verify your laboratory reference value.
• Ensure that your process was stable during the entire procedure.
• Repeat the calibration.
