Just watch the gauge as you turn it over and hold the bleed open, it will give you a very good idea of whats going on.
Not as good as the factory tester, but not many places have them.

hehehe... that only works on some testers. Others.... it just bounces around at 30psi. Some people claim to be able to read that... i don't.

Ask rex.. you shoulda seen that bitch bounce.
