Hi Dave, thanks
I'm on a project outside my home so I'm not able to finish my work on the calibration program for a longer time. Thanks for the hint to the faulty numbers. I did a rewrite of the program - but still not finished - with additional measurement tasks. The performance verification is ready but not tested also the counter check.
Not ready is the calibration for DC, AC and Ohms ... I did this all without my HP 4321A.

The program at the moment consists of the two parts: performance and calibration of the main unit and performance and calibration of the MUX board.

If it would help I can PM you the actual version of the program. Maybe we could finish the program as a 'combination' project if you want.

best regards
Erwin
