Here I'll be posting various test results from random electrical metrology instruments I come across.
For starters - INL sweep of Fluke 5500A calibrator on DC Voltage function using tandem of two good HP 3458A DMMs.
1 V test (5500A on 3V range, 3458As with NPLC10)
10 V test (5500A on 30V range, 3458As with NPLC1)
10 V test (5500A on 30V range, 3458As with NPLC50)
100 V range test (points on lower 30 V of 5500A are not tested in this run
Methods and scripts are explained in good details in this article.
If you have your own INL sweeps that you can share, please join and post in this thread.
