Re: [TCML] SRSG question

[Scott Bogard <sdbogard@xxxxxxxxx>]

Steve,
     In the past I've used a black light and fluorescent tape, it
makes seeing the pattern easier.  I lined up the middle of the glowing
band to the electrodes, but results may vary from one fixture to
another, like John said trial and error is necessary, I never had
great luck with the SRSG, but my cap was way too small to use it
effectively...
