   NOTE:

   • Wrap a piece of tin foil around the tip of the negative (-) tester probe as shown in Fig 6. Press the foil against the wire's lines with your finger without damaging the wire, and inspect the wire.
   • If foreign matter on the glass needs to be cleaned, use a soft, dry cloth to wipe the glass along the wire's lines without damaging the wire.
   • Do not use standard detergents or glass cleaners.
   1. Move the tin foil wrapped probe along the wire's lines, and check for line breaks.
