Inductance Break-Point test

Dec 03, 2006 1 Replies

I picked up a set of screwdrivers from a petrol station and in the kit is a little testing screwdriver.



It has a little LCD type screen on it and two terminals.



The terminals are labelled thus:



Direct Test



and



Inductance Break-Point Test.



The screen reads from 12V to 220V.



I understand the Direct Test is a voltage test, giving the potential difference between the item I test and myself.



I also understand Inductance is the 'electrical field' around a thing that has potential to pass current without direct contact. Does the 'Inductance Break-Point Test' then tell me the potential around the wire etc. and if so what does the 'Break-Point' refer to?



thanks in advance



Inductance is an actual quantified measurement of flux produced by actual current flow.

The inductance break point test uses the detection of magnetic flux to indicate if a wire is broken or disengaged in a sheath. If an extension cord, for example, isnt working because either the hot or neutral is broken - this device will tell you exactly where the break is due to the lack of flux generation.
