Nice one, Did you go the MET/CAL route as well?
Yes, we are running some scripts for 34470A right now.
I noticed it doesn;t like the USB hub (I only have 1 usb ports on my laptop) so from time to time I am getting VISA error.
also if the laptop goes to sleep, seem metcal loses connection to all GPIB resources (the calibrator) so I have to reset everything.
Get a dedicated PC for the job, it will make things easier in the long run. Use a VNC program if you like to connect to it.
I would spend a bit of time messing around with the leads so that you can avoid external influences on them. Do a 10 or 100 MΩ test and grab the leads with your hand, does it affect the readings? Do some tests at the DC mV end as well, as I found a twisted pair of PTFE wires worked much better than the Silicone ones we got with the calibrator (not Fluke). Record these findings and revisit them from time to time as its a great self-learning thing and if an auditor asks you can show them you have looked into various issues.
Also worth buying some fuses for the meters you are about to calibrate because you will blow one at some point as you get overconfident and forget to swap the leads from 3A to 10A. I know a true voltnut would never do such a thing but in reality, it happens easily enough.
As a side comment now that you have the stuff to do the calibration you can now put any meter that fails on a list to be recalibrated in 3 or 6 months to see if it has got an issue. Plus a list of meters that is a high risk from the business side of things, you know the final inspection one and give that a shorter frequency.
IIRC you were going to get a posh meter to go with the calibrator. Start thinking about how you will do regular checks between them to check the calibrator isn't drifting out of spec early.
Have fun. I know work isn't keen on that but try your best to not let them know it.
