Hi!
I am soldering some cables and using 2 or 3 layer of heat shrink hoping that it will serve as well as water insulator. So I decided to do an experiment, in which I covered the end of a 22awg led strip cable with heat shrink and I sunk it into water. My idea was that if water manages to get in, I could measure conductivity with my tester.between the cables. But then I decided to go ahead and measure the conductivity of the water right away, expecting to hear the beep of my multitester, but the multitester doesnt beep, which for me means that even if water gets into the heat shrink I will never be able to know with this method.
How can I then test the waterproofness of my insulation?
