The new History Curve can monitor the stability of a measurement or a system over hours, days or weeks.
Below a history curve is shown. The curve is setup in such a way that two process variables are monitored.
For every minute the following three user selected values are calculated for each curve Min – percentile, Max – percentile and Median – percentile. This provides 24 hours * 60 minutes = 1440 measurements pr day. It is then easy to watch and prove the stability of your measurement solution.
