Gerry,
When you bugged out the script would you please share it with me.  We tried
that, and it looks easy, but somehow I lost my patience to bug the system
out.  I just wanted to use it ones or twice to calibrate the reference gas,
but it would be good to have a script like that in the future.  Actually,
it would be good to have it as an alternative in the library, so everybody
could chose it if one needs it.

hI Anthony--

Yeah, you don't get the bellow adjustment option when using continuous
flow devices--that would be the easiest way out. But you should be able
to us a short ISL script with bascically just the _SetBellowVolt
command, and run it in the extra script section of the method. Ok, so
you'll probably need to incorporate the DualInlet_lib.isl and make use
of the open_right_side and other routines. This is one of those things
on my list for "next month" so I don't have the bugs worked out.

good luck

gerry
