What is a measurement baseline? How do I build it?
When you start working with ChromaChecker™ Instrument Inspector you need to have reference data - in other words you need to know how your instrument measures color. For that purpose, Instrument Inspector Target consists of 42 color patches to assess accuracy and repeatability. Several initial measurements (ideally 10+) are used to create a Baseline - averaged data used as a reference point for all future analysis.
After you have a Target and your customised Baseline, then you can check the accuracy of your instrument at any time by re-measuring the target and comparing against your baseline data.
Baselines
Measured data can be uploaded to one of the following data location/ directories:
This is a place for routine measurement storage. All periodically made measurements can be used for evaluating. File list creates the Easy Mode of Instrument Inspector. On one page all measurement files are listed with some basic analysis results. A quick evaluation of it brings the most important message - Is the instrument valid or not?
Another data location is available in Baseline tab. This location is intended for storing reference files. Every instrument can have more than one baseline.
How to create a baseline?
Each measurement file can be moved to or from the baseline directory. To Move to the directory, select file and press the "Move to baseline" button
Single measurement data may be not accurate to become reliable baseline reference. Therefore, averaging feature can be used to measure files. Select files to average and press "Merge selected"button. Additional dialog box enables to automatically move to Baseline directory and to set it as current. This method creates simple data average.
For better baseline optimisation, Instrument Inspector offers the "Smart baseline" feature. Built-in unique formula will average but scientifically exclude some data, generally measurements with errors.
The Compare function is a flagship Instrument Inspector tool and it requires baselines to work. To compare any instrument to another, the instrument's baseline has to be moved to the baseline directory. It is possible to select up to 5 baselines and compare them to one another. This powerful tool works in both easy and expert mode.
To enter expert mode, choose desired cell in a comparison table and select it. Expert mode can compare selected pairs only.
Partners feature enables to share baselines across system users.
