2 Setting the high level and collecting Cal High data
You must:
• Use the gauge to measure the high process condition.
• Enter the actual level.
This sets the gain of the calibration curve. Perform this procedure before or
after setting the low level.
Before starting the Cal High data collection:

Fill vessel with high process, or close the source holder shutter to
simulate high process.

Have the actual level value ready to enter.
Procedure 3.5: To set the cal high level
3 Collecting the linearizer table data
4. Enter the actual value in engineering units.
5. Click OK .
Note: You must perform a data collection for the low and high level
within 10 days of each other for a good calibration. The low and
high values must be > 10% of the process span apart for the
most accurate calibration. Increasing the process span usually
increases the gauge accuracy.
