4. Enter the actual value in engineering units.
5. Click OK.
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.
Note: You must perform a data collection for the low and high 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
1. Select Calibration | 2 Point Calibration | Cal High Collect.
2. Select Start.
3. Click Accept.
4. Enter the actual level process value in engineering units.
5. Click OK.
3 Collecting the linearizer table data
Note: The simple method skips this step.

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.
