Dave reviewed the video and has approved it to be released. I will allow Dave to comment on the findings.
Thanks Joe, I commented on the Youtube video but will repeat that here:
SPOILER ALERT:
Thanks for the testing Joe. We think we may have uncovered a potential cause of failing at the 2kV impulse and will be looking into that. It was most likely the 2kV impulse on the ohms range that caused the failure at that point, as there is no mechanism whereby the Volts range could potentially fail at that voltage.
The meter is still under development as you mention, so changes are still on-going.
Even if it passed all the impulse tests, it will never be the best choice for those looking for the best high energy rated industrial meter (hence the lack of CAT IV rating, only CAT III, 600V max).
It is also being ETL certified to ensure full safety compliance of course.?
