Hi, Off-shore trying to set up Packer Testing gear ... pressure gauges (GDG) have arrived with glycerin leaking out! It's the weekend so GDG is closed for queries!
There's a top-up hole on the top of the gauge (so I can refill if I can source some glycerin) BUT there's a grub-screw at the bottom of the gauge:
[ul]
[li]what's it for?[/li]
[li]some guys say it should be screwed IN some say left LOOSE ... any suggestions.[/li]
