Step 3: Determine the linearization
Nuclear Measurements are inherently non-linear. The heavier the loading, the more the
measurement becomes non-linear. Since the gauge calibrates near the ends of the
measurement span, the gauge reads correctly there. However, you must load the correct
linearization curve into the Smart Pro before the gauge reads the correct weight in the middle
of the span. This curve depends on the following components:
•
Measurement span
•
Geometry of the source and detector
Procedure 24: Verify the curve is loaded into Smart Pro
1. From the 052 ENTER PASSWORD screen, enter the password for the appropriate
access level
2. Go to screen 528 CURVE # , to view the current values from 1-40
3. Enter the item number and press ENTER to view the specific data point.
4. Check items 0 to 40. If the data is between 0 and 10,000 (0–100%) in increments
of 250, then Linearization is not present
5. Several loadings between 0–100% must be run on the belt or simulated in a static
condition to derive data for this curve. Upon completing the data collection, provide
Ohmart with the collected data points. Ohmart calculates the curve and supplies
41 linearization points.
