Test Equipment Repair - 1 MASSIVE FAIL, 1 success!

Editor's note: The rating at which an MOV begins to conduct is called the "clamping voltage" which is different from the "voltage rating."
Today we take a look at two pieces of failed test equipment. First up, I have a hard time understanding what the adapter does for an Eaton secondary injection test set (part number 140D481G03). Eventually, I confirm my suspicion that the wiring has been tampered with in the field, but I find another hidden problem along the way. Easy fix though!
Second up, I have a look at the Phenix PAD10-25 AC/DC hi-pot which is just... awful. It's not even worth fixing. Don't buy this hunk of junk and don't support companies that shill low effort garbage like it.

No comments after a year ? wth ? anyway I enjoyed it . just goes to show you , you don't always get what you pay for. Some people just don't take any pride in their work. Oh well , thanks for the insight on the rising phenix LOL

Yeah I've been extremely anti-phenix since getting to cold shoulder from their customer service for months on end.
