In ABB model 2000 PGC (on-line Process Gas Chromatogrphs), there are three type of calibration options, External, Internal and Normalizaion. And again there is an option in method table to normalize results to 100%.
When we should use Normalize option in Calibration mode and when in process when it forces the results to 100%.
Please explain or give reference for any website so I can see the details, thank you
