Hello,
I've recently picked up the responsibility for the control charts we use to track our refernce and working standards. The method they were using was to record each reading in an excel spreadsheet and graph the results. Seems like there has got to be better way, especially when using that method to track the performance of a Fluke 5720 or Agilent 3458.
I am considering narrowing the scope and maybe tracking the top and bottoom readings for each range. Still a lot of data but a little better.
Any suggestions on a better method?
Thanks,
Rick

, but I just keep general data on the test instruments to determine a trend. If the process is stable, obviously less data is needed than the new processes/less-stable processes.
