Cheap Voltage Tester

[yaputya]

I bought a screwdriver-type tester for a buck, it has a tiny LCD display and
two finger contacts, labelled 'Direct Test' and 'Inductance Break-point
Test'.
The 'Direct Test' works as you would expect and identifies the Active in a
GPO, but I'm not sure how the other one functions.
No instructions came with it - anyone got one of these ?

Yeah, looks the same but no brand-name on it. Mine is sold as a voltage
tester, no mention of audio use.
How can it measure DC????
