This is the final version of my HV tester. It supplies an adjustable voltage of 0 to 12 kV (or more) high voltage at very low current. It operates from a standard 12Vdc positive 2.1mm center pin wall wart supply.
It has a built in voltmeter, bleeder resistor system, and bright red LED current indicator.
I use things like this for checking coaxial connector installations for stray stands that often will cause future issues, HV low capacitance capacitors such as ceramic, air, or vacuum variables, and for testing tubes for gas or voltage breakdown.
