Calibration Document; A customer asked how calibration is performed in PowerChrom.

The obvious answer is the PowerChrom Manual which describes the calibration procedure.

A video teaching about calibrations is available at https://www.edaq.com/wiki/Method_and_Calibration_Tables

A sample calibration file: File:Calibration is performed in PowerChrom.zip


Why can I see steps in my data instead of getting smooth curves?

It is likely that you have chosen a recording range which is too big and you are seeing digitization. If your peaks are only a few millivolts high, and you have left the default 10 volt range, you will see stepped peaks; the signal and areas will be inaccurate. You should select a recording range slightly higher than the largest signal you will record. Have a look at the Basics of Data Acquisition application note.
