Calibration
Before starting the Cal Low data collection:

Check that the correct parameters (vessel inner diameter, engineering
units, measurement span, and source type) are correct.

Power up gauge one hour before start of calibration.

Fill vessel or pipe with low process.

Prepare to draw a sample while the gauge is collecting data.
Procedure 3.4: To set the cal low density
Note: Perform the data collection for the low and high density within 10
days of each other for a good calibration. The low and high
values must be more than 10% of the process span apart for the
most accurate calibration. Increasing the process span usually
increases the gauge accuracy.
