EEVblog #468 - Uni-T UT513 Insulation Resistance Meter Teardown
Teardown Tuesday. Inside the Uni-T UT513 5KV Insulation Resistance meter. And what happens when you apply 5KV across the range switch of a cheap arse multimeter?
An unboxing anf first impression of the OWON 14bit XDS3202A Oscilloscope.
Note, this was shot as single take for the 2nd channel, but thought it might be better off here but with no EEVblog number. It is NOT a review. If you don't like unboxings and just bumbling around with the scope the first time and ranting then please don't watch it.

Dave show you how to solder a small 3 axis accelerometer LGA surface mount chip "dead bug" style onto a microcontroller prototyping board. This technique allows you to easily prototype projects using tiny SMD components designed only for reflow soldering.
Dave tests the Uni-T UT-513 5000V high voltage insulation resistance tester with the PIntek 15kV HVP-15HF HV oscilloscope probe to see if it's suitable for crude multimeter overload testing, with some spectacular results on the ANENG AN8008
