In Response To: Re: HELP!!! I Screwed-UP (John Anderson)

I figure I would chime in here for a minute...

As for my gauge..it was error on my part of not follwing routine as I normally do...I left the stop-cock open while using a spark coil to test for leaks after cleaning/re-fitting my manifold and had a moment of brain freeze. My vacuum guage was reading a small fade off and I was trying to diagnose where a leak may have developed. I got ahead of myself and was determined to find the leak (as we as know what a pain it is finding it in a manifold.)and just forgot.

Apparently, it was enough spark to fry the gauge. I sent the sensor tube and gauge to Hastings or repair..Hopefully they can fix it..

I always close the stop-cock when processing..For many years I did this with no problem. I rarely get any flash-back but at one time I grounded the pyrex manifold with and electrode to ground. It created too many problems.

The only thing I have been seriously thinking is going to an digital/battery operated gauge instead. Not as accurate but then again if I am off by a little I do not see how that would create problems with tubes. My system has been about to pump below 1 micron with no problem..
