Calibration
Standardization on process
This method requires measuring the process in the pipe with the density
gauge and entering the laboratory measured density into the software.
Advantages: Standardization on process is the easiest method. It ensures
the density gauge reads what the laboratory reads at that density.
Disadvantages: It is not the most accurate or repeatable method. In
addition, it requires a laboratory for results.
Standardization on absorber plates
Absorber plates have the following features:
• Usually made of lead.
• Insert into slots in front of the gauge.
• Require a mounting kit from VEGA.
• Require the use of the same plates to ensure a consistent absorption of
radiation (this is a substitute for the radiation absorption of the material in
the pipe.
Requires emptying process from the pipe and access to the measuring
assembly
Note: Select Lab Sample on the Setup | Cal Parameters tab.
Note: This method requires you to select Default Value and enter the
Standardize Default Value on the SetUp | Cal Parameters tab.
