Calibration
48 LFXG-H Installation and Operation Guide
Table - Non-linear
Use this type for a standard method calibration. It takes into account the
inherent non-linearity of a nuclear transmission measurement, so it is more
accurate than the linear table.
The non-linear table can use data from:
• Linearizer lookup table (data points that you collect and enter during the
calibration process)
• Linearizer data from an earlier model VEGA level gauge
Table - Linear
Use this type for a simple method calibration. This type lets you use a linear
(straight-line) set of data for a linearizer lookup table. You do not need to
collect linearizer table data points. The straight-line linearizer calculates
from the high and low-level calibration points.
This requires you to:
1. Perform a two point calibration.
2. Calculate the calibration.
It is less accurate because it does not compensate for the non-linearity of a
radiation transmission measurement.
