Hi all,
I downloaded labview and compiled the PS350 calib that Dex wrote from a VI into an EXE. You should be able to run it with the LabView runtime only.
I just completed a user calibration on my PS350. I used a B2902A SMU to calibrate current (around 100V) and used a DMM6500 with a caddock HVD5-A50M-050-05 divider to do the high voltage adjustments.
To compensate for the divider error I measured the ratio before starting (mine was 49.978 M over 50.032 K).
Also wrote a text file to record values as I manually tuned them. This was helpful to guide the adjustment procedure.
