Title: Professionals on ISS hard at work troubleshooting with DMM
Post by: Messtechniker on May 26, 2016, 09:59:10 am
At this moment professionals on the ISS are hard at work troubleshooting a connector with a DMM.

See current NASA live stream. Great to see that they have the same sort of problems as we mortals. :)

Now they've got them plugged into an electronic pressure readout.
This is cool, they're expanding A blow-up-module.

Due to NASA budget cuts, they had to use those 3usd dt830 cllones bought off eBay, :)

Apparently they don't know how to turn APO off on their Flukes, so they're having a highly trained astronaut turn it off and on again every few minutes.

@ Fluke experts:

These Fluke 87s - are these off-the-shelf units or have these
been ruggedized in view of rocket launch vibrations?

Looks like the original Fluke 87, I dont see any 'Intrinsically Safe' markings.  Like most space electronics once a version is space qualified they will stick with that version.
A standard Fluke 87 would withstand a lot more vibrations than an person, so I doubt there is anything special done to them, except for extra testing/inspection for faults before launch.
